Are these safe to use for reef tanks?

lights
Sure you could use them but the only thing you'd grow is algae. These lights have a color temperature of something like 4000kelvin or maybe less if I remember correctly and you will be missing a lot of the spectrum and intensity of halides. Some people have retrofitted a certain type of halogen ballast to run Iwasaki 6500k bulbs though.
Halogon is a LOT of wasted electricity into heat. And color spectrum is a lot lower then 4000k actually.
It is a Mercury vapor ballast that is used to fire the Iwasaki 6500k bulb.
