Home Depot Sylvania Metal Halide Bulb

[bagged87blayzer]

Has anyone ever used these. I need the single ended 70watt one? Are they any good. I know they are cheap but they don't list the Kelvin Rating so I don't know.

it seems like others have asked on the equipment and lighting forum and the responses were not positive. i would think a utility light like that would be very low. id ask on that forum for a more specific answer.

Those bulbs are rated at 3000K... very yellow/gold.

Here's the description:
