I've noticed that most of my Metal Halide lamps have been flashy today upon start up. Bright pink flashes from my two remaining little 20w CMH's
in my bedroom, and bright orange flashes from most of my six QMH's in my garage. I wonder why that is? It's very noticeable each time it happens.
I know for a fact that it'll be even more noticeable once I finish installing the final two wallpacks in my garage. (Eight total once I'm done.)
So sometimes during start up they'll simply warm up without any flashing, but other times, they'll flash pink, (bedroom CMH's) orange, (garage QMH's)
until they've finally finished warming up.
My Sylvania QMH's flash orange the most violently, at least so far it seems that way... longer orange flashes.a. but they also take the longest to
reach full brightness as well.
