Hello, i want to upgrade a better light for my frag chamber in my sump to grow SPS and LPS. Looking for a small LED light (hang or clip) but not sure which one is good and need some help here. T
he chamber dimension is 22 inch long, 16 inch tall and 10 inch wide. here is the picture, currently using a LED light from my CAD light 8 gallon.

Not sure how much success you will have with a frag/sump combo...

That being said, I would just get a par 38 bulb and a gooseneck.

Your cheapest and best option...
