well any sps I bought was under MH, and was brown until a few weeks under leds, I dont know if its "browned out" per say, but it does seem to drown out the colors. might just be my experience though

I would say it's more likely a nutrient problem. Lighting of any type doesn't guarantee colors in SPS. If you got a frag from a MH tank and it was brown, it wasn't due to lighting (unless the bulbs were 2 years old). I have over 100 pieces of SPS under MH, and not a brown piece in the tank.

Browning out could be because of the amount of light, not type of light

ahhh so either poor nutrients, or too much/too little light? My mistake :P
at least I learned something today

The only light factors that make a difference are color and intensity, a coral doesn't discriminate against the type of bulbs you're using.

Also it's possible that metal halides could be causing a swing in temp

wouldn't say pour nutrition at all, for years SPS people strived to have very nutrent low tanks, and very high lighting to get the best color out of the SPS. there are still lots of tanks employing this stratagy today with very good results.

to much light would generaly bleach your SPS, not brown them. Any SPS I got that was brown and then colored up came from a high nutrent lower light tank, generaly an enviroment that more suited Softies than SPS.
