Luxbird Waterproof Aquarium Refugium Light Bulb, LED Aquarium Plant Grow Light for Macroalgae and Indoor Plants E26 Non Dimmable (Refugium-18W)

It Works Quite well.So well in fact I had to install a light shield. as not to promote algae in the entire SumpThe coloring is spot on as for a grow tank Algae like Kato or a leaf.Don't need a par meter on this bad boy.GET some kind of light shield if your using in the sump you have been warned

I thought this bulb was going to work out, but it quit working after 3 weeks of use. My Cheato algae didn’t grow that great in that amount of time either. I am returning it instead of replacing it after reading similar reviews.

Good product, wanted more but the last 4 times I’ve ordered to get another, they sent me the wrong kind. Trying to get refugium but keep getting Aqua. 4 times!!!! My chaeto is almost dead because of this. Decided to quit sending back, getting refund and just ordering a kessil.

Has my chaeto growing like crazy. Don't but those super expensive refugium lights this one does the job!!!!!

Love this light! Works perfectly over my saltwater refugium. Grows macros well. I love that it’s waterproof.

So far so good...red/pink light

works great for growing chaeto and good price

This light will only grow hair algae not worth it.
