Bulb color change in a day any ideas?

We just fired up a new Hamilton 2 X 175w with VHO last nite. It was awesome white blue. Came on that way again this morning. Then we shut it off to do some plumbing changes, and now it is green. I am so sick of green yellow bulbs. What happened?

I have heard that Hamilton bulbs arent that great Deb. i will pm you a web site where I have found excellent prices on bulbs ok,,

For how long was it off before you turned it back on?

[EmilyB]

It was turned back on right away.....I was watching...

Thanks Mike, the bulbs came with the unit. I actually used them a lot in the past and had no issues, but if I have to replace them I will, thanks for the link.

I think your not supposed to turn some bulbs and ballasts back on for 15 min or so while they are still hot. (restrike time)
If you haven't already give it another try it might be ok. I had a 150hqi that did the same thing but it was fine after.
