Grew a weed plant with it works pretty good

Ordered this to use to grow macro algae for my saltwater fish tank but never got around to actually using it and got an actual tefugium light but this thing puts out some serious light!

Works great for a saltwater refugium. My chaeto growing like a weed.

I used this as a refugium light. It definitely grows algae very well. The downside is the light angle necessary to mount means you have algae growing everywhere. If I lower it it generates too much heat on the water. Would be great for growing plants I think. The light needs to hang down from the mounting wires.

It has very good coverage, very bright for a little light. We use it for our aquariums, goes great.

I couldn’t grow chaeto with my previous set up, but this light made a huge difference. It’s definitely can be hot to touch

I had another LED grow light and lost a lot of cheato to it decided to switch and micro algae is back.

False misleading and possibly dangerous. The unit I purchased was the 100 Watt unit but the box says 50 Watt. There is no other electrical markings or ratings on the unit. . DO NOT TRUST you will get what you ordered .The switch has an electrical rating but that is for the switch only ..... the light does not The code on the switch tells you XH303 (that is a switch product not the light) and is rated for 250 Volts which the light is not.Certifications from either ETL or UL (c-UL for Canada) are an absolute necessity before buying a grow light. These organizations are responsible for testing any electronic device to ensure it was built with proper safety standards. Installing a light, or any electronic for that matter, that wasn’t approved by a certified organization can void insurance claims if there is an accident like an electrical fire. It can also violate electrical codes in the USA and Canada, making it against the rules to use for non-residential applications and can violate contracts signed with leased buildings.
