New light bulb

I came across a bunch of 8000K rated hqi bulbs on ebay, which is a rarity (on or off ebay) and at a price of $25 I figured I had to try them out since marine bulbs kinda suck for planted aquariums. The manufacturer (based in HK, new company) says these bulbs will induce photosynthesis in plants so it has to have red peaks. Atleast I hope it does.
