My LED night lights are fading and I need new ones. Which ones do you like? I am looking at these Current TrueLumen linkable LED Lunar lights. Aquarium LED Lights: Current USA TrueLumen LED Lunar Lights
Do you think I'd need maybe 3 for a 4 ft. 120 gallon? Blue or white? (I am thinking white)

I've never tried the ones in you link but I have used these. They're small but they're pretty bright and the light is spread over wide area. Two would be plenty for your tank, I used them on my 90 gallon.

These look good too. So you have these on overnight, right?

These are by far the best value. My step dad used them and attached them to his existing lighting.

I use 3 of the blue truelumen over my 90 gallon for my moonlights. They are a nice light. Low profile and barely noticeable. We used double sided tape and stuck them on the edge of the t5 fixture. Mine are on all day until about midnight.

I have been using the blue ones for years and like them. I ran one over the middle of my 90g and now run 3 over my 180g.
