## Questions & Answers

**Q: Is this water resistant Because  my tank has a high evaporation**
A: Hi Diego,
You really need to have a glass or plexiglass cover for this.  The manufacturer recommends use over a glass aquarium panel, so I wouldn't trust possible exposure to water.

**Q: How well does this work for soft corals?**
A: I dont know i don't have any corals in my tank.
I think it would be ok though. Its pretty bright and is a full spectrum light. You can also adjust the brightness.

**Q: The light has three options- yellow/white, blue/white, and blue. The timer only adjusts for yellow/white and blue. What is the blue/white used for?**
A: I use it for a  few hours at night.  It makes my corals look good.

**Q: Can I use 2 of the 24-30 inch for my 55 gallon tank?**
A: i feel like it would be an awkward fit unless you made a rail/hanger for them.

After 1 month 7 days it stopped working..

### ⭐⭐⭐⭐⭐ Great light
*by M***E on 10 February 2021*

I have a 72 Gallon Bowfront aquarium. It’s 4 feet wide and the 1 light seems to light it up very nice although I’d be really happy with two. The timer functions can be a little tricky at first but after setting them it’s a really nice light. I did get it on a flash sale for $10 cheaper so I’m happy with that price point.
