i have a QB96 elite I got a month ago. somehow it ended up not having the heatsink, which was OK I was mounting to my HLG300 anyway. Now as I run out of vertical grow space, I need to remove the 96 from the 300 & mount to the standard QB966-heatsink so I can remove HLG300 and replace w/QB96 to add a foot of grow space. I do not see just the heatsink on their website. wonder if available elsewhere?
UPDATE: i had called and VM was full, then they called me back from caller ID!!! nice! anyway you can get the heat sink separately.
not sure yet, the guy that called had me email warranty dept, no love back yet. seems I saw it was like $20-30 somewhere in the past
