Great Lights

"I’m new to the hobby. The lights are great. I find it useful to be able to adjust the light intensity. My plants looks great and are growing well for a low tech tank. I just bought my second one for a nano tank my local fish store gave me. Could not be happier with my purchase."

— Hoang C. (5/5)

Great color lighting- bad timer options

"Great color lighting nice and sleek really brings out all colors in tank! I don’t really like the controller options you cant set timer to whatever you want only have 6-8-10 hour options and there’s a bright light on controller that never shuts off wasting energy for no reason. Remote needs upgrade for timer or just take timer out and let customer plug into a timer. After setting your timer this bright light just stays on never goes off ? I hate that this light never shuts off WTH."

— Chris D. (4/5)

Great value

"Best prices with shipping and products! Everything came in a timely fashion."

— Guillermo M. (5/5)

Works efficiently, looks good

"Extremely happy with this light so far. Set up took a couple minutes. It fits my 6. 3 gallon UNS long tank perfectly. It looks so sleek. What I love even more is when I turn it off to do something and turn it back on, the light remembers the light cycle I chose! Idk how but that’s pretty convenient. I would definitely order this light again for another tank (and I have 5!)."

— Erin B. (5/5)

All good so far

"Th light arrived with the tank. It appears to be well made and has the functions i needed. I’m still setting up the tank so I haven’t had a chance to use the light yet."

— Tj M. (5/5)

Beautiful light but a bit flimsy of a bracket

"First, this light is beautiful and works well. The inline controller let's you adjust the dim level, timer duration, and on/off status. My only complaint is the bracket is designed to be loose, both how it attaches to the metal light body and the tank. The former is so you can custom adjust it for different width tanks which is a great idea, but it doesn't lock into place so easily moves if bumped. The latter means it slides along the glass edge of the tank. And together, they both mean that, if you bump or knock it too hard, at best it gets all out of alignment and at worst it can easily fall into the tank which i discovered in the first hour after installation. I immediatley unplugged it and was able to unscrew the 2 screws on each end and it easily came apart so I could let it dry out and it works perfectl after, but this really is an easy design flaw that could be fixed. The sliding bracket adjustment should lock and, where it sets on the tank glass, it needs some sort of silicone pad to give friction, or even maybe just some sort of simple clamp. I actually took a little bit of black electrical tap and wrapped it around the bracket rods so it couldn't slide. It's not ideal, but its just too unstable without something. If it wasn't for the flimsy bracket, this would be a 5-star light."
