Luxeon 3up

[Underworld2.0]

My question is :

would one luxeon 3up be adequate for a reef jar with only softies ? 

using the traditional 2g jar?

"probably" but two might be better, depending on how deep/wide it is. If it was me I would spend a bit more and go with a puck from BlueAcro, and bolt it to a cheap heatsink. Run it off of a couple LDD-L drivers and a 18~24 volt power brick.

While I agree a BlueAcro array would be superior, you should have adequate lighting with a single 3up star, though you may have trouble getting a pleasing color to the eye with so few diodes in the mix, especially for softies. I would stress to get a high-CRI white to help you see the non-fluorescent colors of most softies 🙂

Like Ben said a 3 up will work depending on the diodes chosen.

 

Blue acro array would definitely be better but much more expensive comparatively.
