Luxbird par38 Aquarium Light, 18W Full Spectrum Waterproof LED Grow Light for Nano Tank (Par 38)

The media could not be loaded.  First impressions: not a bad bulb! All diodes were functional out of the box. Assuming that the PAR graph provided on the product page is accurate, it’s a more than acceptable bulb for growing most any coral, with the biggest limitation being placement.*Bulbs were put into service on 07/10/2019, and I’ll update at 3 months, 6 months, and 12 months, so long as they survive that long. Aquarium itself was fully cycled, and 30 days old at time of light installation.*Pros:Decent spectrum blending, with minimal disco ball affect mounted 12” above waterline.Price! Lower price than the other clones of this bulb on amazon/eBay.Sturdy construction. Would probably safely survive an accidental dunk in water.According to provided PAR graph, decent spread in a 12”x12” grid, and acceptable out to 16”x16”.Fulfilled by amazon, so quick delivery.24 month warranty on bulb.There are several cons to keep in mind. None of these, it should be noted, have affected my overall impression of the bulb itself, but could affect long term functionality.Cons:New product on Amazon, so unknown reliability.No external heat sink.These bulbs are *heavy*, possibly too heavy for a clamp lamp.Pretty narrow optics, and need to be mounted 8”+ above the water to avoid a spotlight effect, and allow for better spectrum blending of the 5 diode color outputs.No seller contact info on product, only a card with contact information *after* product has been received.

Good product water proof and nice a little to much of a spotlight and a little more white than I’d prefer

I was hesitant to purchase this light, but after using it for a little while, I have ordered 2 more and have decided to replace my other lights with this one. Color is great, my fish are super active, and the price is right. This is a great light for the $$

I love how bright this light is! It makes my tank look so beautiful. The size of the light is nice and big, perfect size. I am so happy with my purchase.

I was surprised! It doesn't look that bright to the eye, but the macro algae in my sump is growing like crazy!!! Way more than previous!

Really good bulb and good quality I'm not sure if it is water proof and I don't want to try

Gives a perfect blend of color. Use them for over a fish tank and really allows the colors of the fish to glow!
