What would be the better choice for lighting over a 16inch x 16inch x 16inch refugium? The CSL has a 10,000K Premium Daylight and Ultra Actinic bulb. I think the LOA is a 6500k bulb.
I have a LOA fixture still going strong. (I did however drill a dozen vent holes.)
It depends on your budget. LOA = $30. If it won't be seen (like if it's in your stand) I'd get one.
If your fuge is going to be seen, I'd get the CSL. I HATE the color of the LOA beside my CSL tank. It looks dingy compared to my 10k + 7100blue lit tank.
