It should be fine.. Over a year ago before I took a break from the hobby, I had the RapidLED PAR38 (80 degree optics, mounted 6-7" above water, dimmed to about 90%, which is the max my dimmer would go to when used with this bulb) over a standard 5g with LPS and Zoas with no problems. Since the bulb is dimmable, just make sure you dim it and ramp up over time to acclimating your new coral additions.

I used this with my Par38 for dimming and it worked great.

Since the Nuvo 10 has a cube-ish display (12" l x 12" w x 13" h), a single par38 should be enough spread to cover the entire tank. With some simple math, you would need to mount it at the following height depending on the lens option you go with:

d = degree optics
12" / 2 = 6"
tan(d/2) = 6" / H
H = 6 / tan(d/2)

Approx 7" off the water surface will give a 12"x12" spread on the surface for 80 degree lenses
Approx 10" off the water surface will give a 12"x12" spread on the surface for 60 degree lenses.

I recently restarted the hobby and chose the Nuvo 10 as well. I bought it from an LFS that didn't carry the standalone tank so I just sold the Skkye LEDs to someone here and opted for an AI Prime over my Nuvo 10 instead. They are a little expensive but they are fully featured. But I wouldn't recommend them if you are planning to upgrade tanks in the future. The Par38 from RapidLED are great if you just want something for now and don't mind that they're not the prettiest or coolest looking lights. I liked the color it provided and they're dimmable with a simple accessory.

My mistake. If Nano 10 is more cubish, then a single Par38 would be a better choice and provide enough spread still compared to the bigger, more powerful LED you posted the link for.

With the kessils or ai prime you can keep everything from mushrooms to across in the 10g nuvo if you keep up with water changes

Thank you everyone for the quick responses, I'll see if I can find a used Kessil or AI prime and if not maybe I'll go with the par38 from lightboxled.

I think Coral Hoarder was selling an ai prime on here a few weeks ago, not sure if he sold it or not.

I would suggest kessil a160. That's what's on my nuvo 10 gallon and I have some sps that is doing really well amongst a lot other coral. And I have it set at 40% (sometimes I think it's too much) which leaves lots of room to be able to upgrade tank size if you choose in the future. It's expensive but you will never regret it.
