Metal Halide Retrofit

[kool55]

I have 6 Cooper 400 watt Low bay[14 FT ] fixtures in my shop . 2 rows of 3 controlled by 2 switches. The back row is out and its time to repair. They are 15 years old now. I want to keep the fixtures because the are cut into the ceiling. I found a LED bulb that requires a ballast bypass. Thats fine since a least one ballast/capacitor is bad . The lamp I found is from Superbrightleds, the HBR-57K150-EX39. Any thoughts? Trying to add pics.

Verify that it's rated for enclosed fixtures. Dont just take their word for it, get a real spec sheet from the manufacturer.
Superbrights sells mostly chinesium, which this is. No name brand, so you have no idea of the quality.
Better products are out there. Look at Light Efficient Design #LED8232M50. You'll need to verify the dimensions to see what will fit. For 400w equivalent, you'll be mostly looking at highbay lamps.
Good luck,
