We installed these fixtures on existing light poles. The previous fixture was 175 watt metal halide that was about 25-30 years old. we were constantly repairing and rebuilding these fixtures that increased the cost of maintenance with the electricians to fix the problem and special lifts
I'm replacing 250-watt metal halide fixtures with the 50 watts led fixture. They look awesome and have at least the same output if not more. A cleaner whiter light output also. I'm using them as uplights on a commercial building.
