Cheap Ebay LED

[physicsguy]

Hello,

I have a 3 g pico p and running. Currently using a 20 watt 50/50 coralife mini pc bulb.

Corals seem to be doing fine but wanted to see if anyone has ever used these before.

These are 9 watt

These are 15 watt

Would one of these be better than my current option?

Thanks you!
