Ati coverage for a cube 93 or 100 cube

[derek yoonie]

30x30x24 or 31x31x24 , have doubts about a ATI fixture 24"x 6 bulbs covering that area , anyone with par levels for it ? mainly want it to be most sps dominant with some lps (70/30) or is 8 bulbs a MUST? thank you reefers

8 bulb. 6 bulb is only 13.4” wide. 8 bulb is 17.5” wide.

I took an 8 bulb, removed 2 center bulbs and put LEDs. I’ve seen others add reefbrite LEDs to these fixtures as well. If you are going primarily SPS I wouldn’t skimp in lighting. Hope this helps.
