Need help with light frame dimensions 3x3

[hornedfrog2000]

I was hoping someone could help me with the spacing of my cobs, and the dimensions of my lights frame. Ill be running 8x 3590 over a 3x3 flood tray. I would assume id want the frame to be a little smaller than the table itself. I'm using kits from timber so i have thr ledil reflectors too... thanks for the help.

Pinned heatsinks they can slide or be screwed in place. Hence extra holes

Cool. Thanks. Yep. Im using the pinned sinks too

I've also found that I like smaller than bigger. Meaning if I need 8 cobs, two 4 light units is more convenient.

On a side note, gorilla glue mounting tape. No drilling and sticky as hell. I've run a strip down a rail and you can slide cob.

Any reason you went with 18x24? Should i be ok with 30x30?
