recommendations for LED?

[Argentiner]

Can anyone recommend a LED night moonlight for a 6 foot tank? I'm getting a different light fixture and it does not have one built in, and not sure what to put on it, as I like being able to see in the tank a bit at night. I'm not even sure how many to put on. The light I have on now has 4 single moonlights, and I like it, but I'm read some people put Chrismas light strips on and they would be cheap to buy. Any thoughts would help!
