Hey guys, When I was at the Manhattan reef Swap few weeks ago I played the raffle.. This bulbs are no longer for sale by ANY retailer other than reefbrite, which is currently down right now, atleast thats what i heard from the owner at the swap (She attended) So if you've got a 250w ballast, these are the choice for you! The are 10k/20k and fire off each time the switch is turned on/off.. BRAND new still have the sticker on the box.. Looking for about $100 for it considering i think she said they retail for $120 or something? Give me offers on what you guys have, im open to trades maybe..
