## Questions & Answers

**Q: how can I use off & on only?**
A: It's a dedicated power button. Plus the instructions come in the box will tell you how to operate the device. The automatic feature is very useful in any event though

**Q: What is the size of the light body? I want a light to put in an aquarium hoid yo replace an existing light. I need something that is 3¾x 21"**
A: My light is 4 inch wide x. 17 inches long and about 3/8 of an inch thick. It fits nicely on a standard 10 gallon tank with about an inch on either side.

**Q: Would this light fit a 20 gallon long that isnt rimless?**
A: If you purchase the 22 watt or the 26 watt it will fit. A warning to those wanting aquatic plants - this grows algae like crazy but every plant in every tank I have this brand of LED light on has died or is barely struggling to hold on. So I wouldn't recommend it for planted tanks.

**Q: I know I can adjust the light intensity in manual mode but can I adjust the daylight intensity when it is in auto mode so it isn't always 100%?**
A: By auto mode, you mean S1? The brightness is one of the programming options for this mode.
