It's weird because sometimes the flashing colors with my QMH lamps seem either pinkish orange or orange. The flashing in the ones at my gym class were orange all the time, and they would flash normally in twos or threes, before fully warming up.
The flashing with my 20w CMH are always pink, never orange... which makes me wonder about my CMH Philips lamp for my Wallpacks.
I've seen that lamp flash before warming up... but the flash from it was purple, and very slight. I have never seen that lamp do any orange flashing yet.
