I went to a lighting chart and with my coralvue 400 watt ballast looks like the megachrome coral bulbs have the best par? according to Sanjays chart! anyone use these? looking to upgrade from my 12k reeflux?
thanks Joe

I used those when I had my Geissman infinity fixture. Never had any problems with them. Always liked the way the looked, the corals seemed to like em too

Buy the Ushio's. Same bulb at a better price.

I have used one before the 14 k and it is very yellow to my eye actually tried another because i thought bulb was bad but it to was very yellow almost looks like 10k bulb, it does not have the crisp white like reeflux 12k. Just my opoinion
