All about LED commercial and Industrial LED lighting



    In our last article of things you must know before switching to LED (you can find it here) we learned about wattage, types of tubes, Bulb and tubes bases or connectors, and lenses. We also started understanding the switching to LED business with the first article of this series: read it here

    In this last article of the series, we will learn more concepts to be sure that when it is time to choose our next LED bulbs or fixtures, our decision will be base 100% in knowledge and understanding.

    Please remember that these are informal definitions, not academic ones and this is because our goal is for you to quickly understand the ideas and not to make a scientific dissertation about them.


    This is basically what color we perceive the light to be. It is measured in degrees KELVIN (K). The higher the number the blueish the white tends to be, and, vice versa, the lower the number, the yellowish.

    • 6000K: Typical color of fluorescent tubes. Probably you’ll find 6,000K in a hospital and because it has a blueish hue, it is not the most popular one.
    • 5000K: is considered Natural, hence the name "natural white". This is the color of the light outdoors, on a sunny day. Seems to be, as an average, the most used.
    • 4000K: This is where the color starts tending to yellow, but not quite there yet.
    • 3000K and less: Definitelly a yellowish hue. Typical color light of the old incandescent bulbs. Ideal to create warm decorative effects.
    Know before switching: Color temperature explained Color temperature: A clear approach

    A note on color temperature:
    Terms like "cool white" or "natural" or "soft white" are nothing but marketing attempts to describe what a manufacturer is trying to sell by making it appealing to you.

    This is why their meaning is not consensual and you might find a "Cool white" that is actually 4000K or "Soft whites" that are 5500K. Really important to know before switching to LED!

    We have tried to make a classification according with reality and the actual "look" of the color.

    Regardless, and to avoid confusion, ALWAYS buy by degrees Kelvin which is a standardized measurement and cannot be 2 different ones, independently from the vendor.


    Another must know before switching to LED is the IP. It measures the level of intrusion that a product can stand. IP stands for ingress protection or intrusion protection and this number is especially relevant when it comes to determine whether the product will be installed outdoors or indoors.

    The first digit refer to solids and the second to water:  generally, in LEDs, you will find: IP40, IP64, IP65 or IP67. Take a look at the graphic to see the meaning of each number.

    Know before switching: What is the IP rating? IP Rating and its significance

    Feel free to navigate our website searching by this important attribute, IP40, IP64 or others


    Basically is the amount of light emanating out of the bulb or fixture.

    The higher the number, the more light you get. Even though it seems that this is a good measurement to compare technologies, it is a tricky one:

    KNOW before switching! Fluorescent tubes and HID lamps manufacturers use as "lumen output" the “initial lumen” which is a different measurement than the average, used in LED, hence a lot of confusion comes from comparing with lumens.

    Most of the times is better to stay away from comparing lumens.

    Now you know a little bit about the all the necessary concepts you must know before switching to LED.

    You also probably noticed that, consequently, all our product’s pictures have ALL the information you need to know to make a quick an effective buying decision, much as it is explained in the following picture.

    Welcome back!

    In our last article of things you must know before switching to LED we saw what are the different technologies that we might be replacing and an easy formula to estimate the equivalent wattage for an LED (for an LED technology that generates around 130 lumens per watt).

    Now it is time to review some concepts that you MUST understand in order to make the right decision when it comes to choose LED lamps or fixtures. These are some of the things you must know.

    What follows are informal definitions, not academic ones. This is because our goal is for you to quickly understand the ideas and not to make a scientific dissertation about them.

    Some definitions:


    This is how much energy the lamp uses to function, therefore the smaller the number, the less you spend in your electric bill. In our website, here, on the left hand side, you can search by making a selection by wattage.


    Tubes are measured by how long they are (in feet or inches and from pin to pin)) and how thick they are (the diameter, in 8th of an inch:

    Name Diameter or
    T4: ½” ½”
    T5: 5/8” 5/8”
    T8: 8/8” 1”
    T9: 9/8” 1 1/3”
    T10: 10/8” 1 ¼ “
    T12: 12/8” 1 ½ ”

    You can find more information about tubes in our website following this link.


    The metallic twisting part of the bulb that holds it in place. It can be:

    • E26, Edison or Medium: Is the standard base that you find in a household. The number is due to the diameter in millimeters of the base, in this case 26. Click here to see our products with an E26 Base
    • E39 or Mogul: More often used in an industrial or commercial setting. While it looks the same as the E26, it is a little bit bigger (39 millimeters diameter). A list of all our products with a base E39 can be found here.
    Things you must know: different bases Medium and Mogul Base

    The metallic single, dual or 4 pin connector that is at the end of each side of the tube. It can be:

    • Bi-pin G13: 12.7mm (or 0.5”) from pin to pin. You will find this connectors in almost every T12’s, T10’s & T8’s tubes.
    • Bi-pin G5: 5mm from pin to pin. They are in T4’s & T5’s tubes.
    • FA8, nipple or single pin: In 8 footers tubes.
    • R17d, Recessed double contact: Only in high output lumens tubes, not common.


    Another one of the things you must know is what a lens is and if it has any kind of impact in your buying decision. The lens is the covering or protection of the light that might also provide diffusion or not.

    It can be clear (you can see through) or frosted, milky or white (you cannot see through).

    This is just an aesthetic option. If the light will be at eye level, we suggest buying frosted, otherwise, any of the 2 will do.

    Even though one gives out a tiny bit more of lumens than the other, our eyes are not able to see the difference.

    Stay tuned, since in our next posting, we'll review the concepts of color temperature, IP and lumens and with that you will be ready to buy knowledgeably your next LED's.

    We truly hope this information is helpful for you and, furthermore, helps reducing researching time and ease your transition to LED lighting.

    Since we are here to help, please do not hesitate contacting us for more information or to show you different economical options for your next LED switch.

    Switching to LED

    So, you made up your mind and you said to yourself: "I am switching to LED".

    A lot of people told you about it, you know and you heard about all the benefits yet you have been procrastinating it for quite a while.

    FINALLY, something clicked and you said "ok, it is time", only to find out that it wasn't that easy...Switching to Led: you seem to be loosing the battle.

    Nothing is more frustrating than picking up the phone to realize that you know ABSOLUTELY NOTHING about the subject. There are so many new terms, classifications and options that what you though (and should be) an easy task ends up being a mission you are not really sure you will be able to survive…Switching to LED seems to be a nightmare!

    Therefore, to make your life easier, LEDRadiant have prepare a series of articles which provide an easy explanation of the things you MUST know beforehand so you can make a swift and fast transition to LED. Believe us when we say: Switching to LED is easy

    First: the WHAT

    First of all, if you are REPLACING an old lamp, you NEED to know WHAT type of lamp you are replacing. It might be:

    • Incandescent:  Typical bulb in most residencies up to 15/20 years ago...(is an electric light with a wire filament heated to such a high temperature that it glows with visible light-incandescence-)
    • HID (High Intensity Discharge): Mostly on commercial settings, (These lamps replace the filament of a light bulb with a capsule of gas. The light emanates from an arc discharge between two closely spaced electrodes. This discharge is hermetically sealed inside a small quartz glass tubular capsule.) They can be Metal Halide, Mercury Vapor and Sodium Vapor. or
    • CFL (Compact Fluorescent Light): Fluorescent tubes are in this category. (In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating -called phosphor- on the inside of the tube, which then emits visible light.)




    Switching to LED: Incandescent Lamp Incandescent Bulb
    Switching to LED: CFL Bulbs CFL Lamps


    Switching to LED: HPS Bulbs HPS Lamps
    Switching to LED: Metal Halide Bulbs Metal Halide Lamps

    So, switching to LED implies 2 things: knowing what to replace and...

    Second: WATTAGE

    You need to know what’s the wattage of the lamp you want to replace. To find out this, you can read the wattage on the lamp itself (most of the bulbs have this information) or look for the information on the box of a spare one.

    As a result, with these two pieces of information, Type and Wattage, it will be easy to determine the equivalent in LED that you need and with this, the switching to LED will be a breeze.

    As a general rule, is there any way to calculate the wattage equivalency in LED?

    YES!, as a really usufull starter, follow these simple formulas:

    • Incandescent: Divide actual wattage by 11
    • CFL: Divide actual wattage by 2.5
    • HID: Divide actual wattage by 4.5


    • If you have a 400 Metal Halide (HID) bulb in a high bay, you should replace it with: (400/4.5= 88.88) a 100W LED and this way you will have a little bit more light than what you have now. These are some of the options you could go with when you are looking for replacements when you are switching to LED.
    • You have a Fixture that is using a 14W CFL lamp and you want to replace it with LED: 14/2.5=5.6 . So any LED 6 watts an up will be a good fit. You can check here some of them.
    • What about replacing that old 150W Incandescent lamp? 150/11=13.63. So starting at 14W you should be good to good! Here are some good replacements for that

    Since LED technology is constantly evolving, this is going to give you just an ESTIMATE value, a rough idea of what LED wattage you’ll need to replace the old lamp and switch to LED.

    There are other factors to take into account (like height, area to cover, type of light/fixture, etc.) For a more precise evaluation do not hesitating contacting us.

    These formulas are an estimate based on an LED technology that generates around 130 lumens per watt. This is a value that raises constantly with technology improvements, hence changing the formula on a regular basis.

    That's all for now!

    We truly hope this information is helpful for you and, furthermore, helps reducing researching time and ease your switching to LED lighting project.

    Since we are here to help, please do not hesitate contacting us for more information or to show you different economical options for your next LED switch.

    In our next post we will learn the meaning of some concepts like wattage, types of tubes, Bulb and tubes bases or connectors, and lenses.

    Have a wonderful and illuminated week!

  • Canopy Lights Are Definitely in Demand

    How can you significantly reduce energy consumption and thus overall energy costs at your facility…retrofitting with LED canopy lights is certainly a great way to start. Perfect for example in gas stations, these LED lights burn longer and far more efficient than more traditional style bulbs. With lifespans that can range from 50-100,000 hours, the LED canopy lights are a product that you can certainly get behind.

    Given their intensity and brightness, these canopy lights are phenomenal when it comes to outdoor use. People want to feel safe, and in order to feel safe they need the surrounding area to be lit up. Only LED lites can do this to the point where drivers become less anxious and subsequently feel more secure. Isn’t that what you would want for your facility…

    Additionally, as these types of LED lights offer greater flexibility as far as being able to equip them with various controls, they tend to save even more in energy costs. So why should you investigate retrofitting with LED canopy lights…The reasons speak for themselves really. But if you look briefly at a quick comparison between let’s say for example, metal halide lights and LED lighting products you will certainly see the reasons are quite clear:

    • High intensity discharge lamps take 3 to 5 minutes for full output and sometimes up to 20 minutes to stabilize the color temperature. LED light output stabilizes in less than 1 second.
    • Another characteristic of HID lamps is that if switched off, they cannot be restarted until a waiting period of 5-10 minutes. LED lights can be switched off and on immediately.
    • HID lamps come in basically 2 color temperatures, either cool white for metal halide or yellow 2100-2300 Kelvin for HPS (high pressure sodium).
    • LED lights operate at 120F to 180F while metal halide lamps operate at 1500F to 1800F. This means a more efficient overall luminosity as well as a more effective end result.
    • Potentially the number one advantage that LED canopy lights have over halides or any other type of lighting fixture for that matter is in the average lifespan. Boasting anywhere from 50,000 to over 100,000 hours of life, the LED canopy light is guaranteed to save you time and money,
    • While perhaps the initial output may be a little bit more as far as the LED bulb goes, the overall cost is significantly less. You will save with LED canopy lights. Because of the fact that there is much less maintenance involved, because the lifespan is a great deal longer and because the product is in general that much better, you can rest assured that LED canopy lights will make your wallet smile.


  • UFO LED Lighting; The Wave of the Future

    Ideal for warehouses and just about anywhere that requires a rugged, waterproof and long lasting light source, the new UFO style LED lights are certainly making a huge splash in the lighting industry. Easy to install and more attractive than some other types of lighting, these UFO LED lites are at the top of their class. If we consider similar products featuring for example metal halide or CFL lamps, we see that the LED UFO’s lifespan is much much longer. Potentially upwards of 100,000 hours, these fixtures require very little maintenance, which equates to big savings for you in the long run. And who wouldn’t want that…

    Smaller and more compact than other forms of LED lighting, The UFO LED lights still put out the same amazing brightness and luminosity and its durable construction make it great for spaces that may be more inclined toward rougher weather or more unpredictable elements. Given their design and functionality, light is sent downward extremely effectively. In the end these UFO LED products are cheaper to run, more efficient in function and certainly eye catching and fashionable.

    The other wonderful thing about these new LED UFO style lights is the incredible ease when it comes to installation. Projects that might normally take hours or even days, now only take a comparatively short amount of time, as this particular LED light. Lessening the likelihood of complications or malfunctions, the sheer simplicity of retrofitting with these types of LED lights is certainly a very welcomed feature of the product.

  • LED Pole Lighting Fixtures: Illuminating Your Exterior

    One of the trickiest and most labor intensive areas to replace and maintain lighting fixtures and the corresponding bulbs is outside on those not-so-easy-to-reach pole lights. A very necessary area when it comes to light requirements, parking lots, walkways and general exterior applications are hugely important for your business or office complex. Even projects involving street light installations are made that much better and more efficient by using LEDs. People coming and/or going later in the day certainly do not want to be left in the dark, having to “feel” their way to their cars. For purposes of safety and security, you want to ensure the best and brightest lights possible. Utilizing LED pole lights is not just a prudent move, it’s a cost effective one as well.

    pole-parking_lot_3_2_1_1_1_1_1 (2)

    When weighing the decision of whether or not to replace your old pole lights with highly efficient LED versions consider the following:

    • Maintenance: LED Pole Lighting, unlike traditional commercial grade variants of such lights, are not difficult to access nor do they require a great deal of maintenance. Boasting an impressive lifespan of up to 15 years, the amount of bulb changing and replacing that you will be doing is minimal. Cost wise, that adds up to positive savings in the long run—money that you could put back into your business.
    • Lumens: As some LED Pole Light Fixtures are often achieving over 100 lumens per watt, the direction and intensity of these lights is far superior to any comparable product on the market. When you’re talking about safety and security especially, this is an incredibly important factor to consider.
    • Flexibility: Various lighting controls can also be integrated with these lighting products. This equates to a far more efficient and cost effective performance, like photocell dusk to dawn control.

Optimal for wetter areas and moist, humid conditions, LED linear lighting provides constant, bright and dependable illumination even during the most treacherous of weather events. And exterior use isn’t all this fixture is limited to. Perfect also for indoor applications that present moist and/or more rugged settings, LED wet location linear and LED tri-lighting is the answer.

    Constructed out of waterproof, extremely durable materials, these lights are highly efficient and extraordinarily resilient. Brighter than multiple fluorescent bulbs combined, LED linear lights are ideal for environments which pose a challenge for lamps that may not otherwise be up to the task. So what types of applications are these specially designed LED linear pendants, LED wet location high bay lights, and LED tri lights useful for…

    Where Can You Use LED Linear Lights...The Possibilities are Endless!

    Certainly outdoor use is within the wheelhouse of the LED linear pendant and bar type lights. Rain, snow, sleet--more reliable than the postman--these fixtures feature an expected lifespan of greater than 50,000 hours. Braving any storm, they maintain their luminosity and provide excellent coverage regardless of weather conditions.

  • LED Wall Pack vs. Metal Halide Wall Pack

    Far more economical to run, not to mention more efficient in the long run, the LED Wall Pack light is a great investment. If we look at the Metal Halide Wall Pack, you will find that it takes a 250 watt bulb of one of these types of lamps to equate to a 70 watt LED comparable light. Part of the reason for this is the fact that a great deal of the metal halide’s energy is basically burned up as heat rather than as light. This is certainly not the case with the far more effective and more temperate LED Wall Pack fixture.

    wall pack light

    Approximately 80% more efficient than similar types of lighting, LED is most definitely a clear choice. Perfect for outdoor applications, the LED Wall Pack’s rugged and durable construction can hold up to some intense elements. Not to mention, their incredibly longer lifespan make it so that particularly in those more difficult to access outdoor areas, maintenance is minimal. Yet another savings, putting money back in your pocket.

    Not only are the LED Wall Packs a better choice and a great bargain, they also produce a far more favorable light. Delivering up to 7000 lumens, LEDs create a much brighter atmosphere—and when you’re talking about light, of course brightness and illumination are what count.

    So why should you switch from your Metal Halide Wall Packs to LED…We’ve mentioned heat, efficiency, lumens and durability. What about cost? Over a period of time—a relatively short period of time—any money that you may have spent, or any additional expenses incurred as a result of retrofitting with LED Wall Packs, will be made back, plus some. The LEDs lifespan (up to 20 years), combined with greater efficiency, combined with a much cooler running bulb, all add up to tremendous savings in the end. Your ROI is unbeatable when talking about an LED Wall Pack versus a Metal Halide.


    Not sure exactly what you need or what the best lighting plan/layout is for your particular building. LEDRadiant’s expert staff will be more than happy to help you. With years of experience and knowledge under our belts, we can direct you toward the best possible LED Wall Pack solutions.

  • Why it’s better to bypass the ballast when retrofitting to LED tubes?

    More and more businesses and industrial buildings are switching out their old lighting systems and retrofitting with a highly efficient and far more productive LED lighting system. Some of the issues they are running into involve the old ballasts which were put in place to accommodate the fluorescent lighting previously used. A ballast essentially acts as a mini transformer of sorts which is necessary to light the lamp. Most heat the electrodes and in this manner start the lights. The question is, should you utilize these ballasts when integrating new LED technology? The overwhelming answer is no…

    For one, it is not necessary. LED tubes have their own internal driver. So while bypassing the ballast may require a bit more work as far as installation goes, connecting directly to the line voltage is certainly the smarter thing to do. Ballasts generate unnecessary heat, and they subsequently wear out before the actual LED tube does. So maintenance costs should definitely be taken into consideration if you do not intend to bypass the ballasts.

    Additionally, when replacing fluorescent tubes with LED’s you need to understand the nature of the ballasts you currently have in place. Connecting an LED lamp to an incompatible ballast will certainly cause issues. While some have argued that plug-n-play LED lights ultimately save time and money over the ballast bypass LED’s this is not necessarily the case. Often, companies experience a very costly trial and error process trying to retrofit LED lighting as they are unaware of the exact type of ballasts currently installed, whether instant start or programmed start, magnetic or electric.

    In the end, bypassing the ballast just makes more sense. Primarily, you are implementing a system which is quite a bit more efficient than if you opted not to bypass. The ballast itself wastes anywhere from 15-30% of the total electricity used. Over time this equates to lost energy which translates to lost money. So although initially the work may be a bit more labor intensive, in the end, as far as efficiency, maintenance costs, and overall productivity, it looks like the best solution when retrofitting with LED lighting is to bypass the outdated ballasts.

    Not sure of where to start. LEDRadiant is invested in your happiness and so we are dedicated to helping you with all of your lighting needs. Contact us and we will certainly be there to assist you!
