400W Metal Halide on a Mercury Ballast « on: June 21, 2008, 11:14:01 AM » Author: GE M-400A1
Hi, Could a 400W MH run on a 400W Mercury ballast. I want to know because my TB 125 has a 400W Mercury ballast and i don't have a 400W mercury bulb. Thanks

MH lamps will blacken much faster on MV ballasts faster due to more sputtering and have a lot shorter life too.....

Would it be safe to run a 250 MV in my TB 125!

Not recommended. It might cause the lamp to explode due to higher temp and pressure than normal. Lowes (Sylvania) or Home Depot (Philips) sells the 400w mercury vapors but they're coated.

Why I like LEDs on top of other lighting tech?
LEDs = Upgrade 95% of the applications. (That is if you avoid eBay's LEDs).

LED brainwash? No, people uses them cuz they work well for them.

No worries, I will be sending you a 400w merc hopefully shipping it out this weekend. BTW I tried my brand new 400w Sylvania Metalarc (probe start) lamp on my 400w MV ballast and it didn't even glow. Guess it really needs the higher OCV of a metal halide ballast to even start.
