I'll have to measure to be sure since it's been a while since I hung the lights and I don't remember but my goal was 12" for the lamps (not the bottom of the reflectors but the bulbs themselves). Wanted a little more height for a couple reasons: reaching in with a hand without burning my elbow, heat mitigation, and better coverage/less shadows/less-straight-up-and-down-angles so that corals have some hope of side lighting since before with lamps closer to the surface I always had corals dieing out at the bottom and I really want to avoid that with this tank. I forget but there was a fellow out east with a similar sized tank to my own (was big on reefescape.ca when that board was still around) who went 12" and I sort of modeled my lights after his tank.
