Hi guys,

Can I use par38 led bulbs on a 2 foot deep tank?

I'm inclined to say no. I saw one on a 14g nano tank and it didn't appear very bright to me.

Depends on how wide you want the light to spread. But generally it won't cut it.

I was thinking about using them side by side to get full coverage, to replace an LED unit. That way if one of the LED bulbs blows I can just replace the bulb and I don't have an entire light out of action to fix anything.

No reason they would not work, they are just 3W led clusters after all. Your ideal would be to get narrower optics, say 60 degrees (most common is 90), but even then you'd be fine. @rockerpeller used two over his 75cm and felt the penetration to the bottom was fine.

I will not be keeping any LPS or SPS - ever ;) But I won't have the option of moving corals higher in the tank as there will be no live rock structures. Zoas, morphs and BTA's will be in the lowest areas of the tank.

if thats all your having the only worry i would possibly is the bta not getting enough light in saying that you can target feed it to keep it happy :)

The penetration was fine and it happily kept a couple hammers thriving on the bottom. It all depends on what you want down low.
