Review: Fantastic fully programmable light with battery backup. - I have this light on a 40g Marineland breeder tank that has a 36”x18” footprint. This pic was taken with the light set at 10% brightness on full spectrum. Without a doubt, if you want to grow plants this is an absolute powerhouse. My Cichlid breeder tank has fake plants in it as the cichlids will eat live plants and in a 40g they serve to break up sight lines and reduce aggression. This tank was set up 2 weeks ago and is cycling with 1 fish in there. Programming takes some time but once you figure it out the light is awesome on its 24/7 setting that starts with a yellow sunrise migrating to full day sunshine to a yellow sunset to blue moonlight to off. All fully programmable for color, time and brightness. Well worth the extra $. If you want to grow live plants I can’t even imagine how well they would do under a light that can deliver so much power if you turn it up. I have to keep it lower with fake plants to avoid an algae bloom. With a tank packed full of live plants you’ll grow a jungle in no time.
Review: Great light spectrum for aquascapes/aquariums - Great light spectrum. It has a lot of features and color options I still need to figure out but but just off the brightness and clarity it beats anything at the box pet stores.

## Questions & Answers

**Q: Is it designed to avoid promoting algae growth?**
A: Yes, the SR-657 aquarium light can be turned on/off at the time you set, and the 20 levels of brightness can be adjusted to effectively prevent algae growth.

**Q: Is the battery included? Do I have to use batteries? How long does the battery last?**
A: Yes, CR1220 batteries are included. The battery is only for memory function, and the LED light and controller can work without the battery. The battery only consumes power when power supply is disconnected.

**Q: Can this light help plants grow?**
A: Of course! The spectrum of this aquarium light increases the intensity of red and blue light, which is more conducive to the growth of rhizomes and leaves of plants, and promotes the natural circulation of the water tank.

**Q: I'm having trouble programming, what should I do?**
A: Tell us the lighting schedule you need (start time, end time, light color, brightness), and we will assist you in setting it up step by step. We usually reply in 12 hours.

**Q: I need to have the night mode start at 6pm but the number is skipping?**
A: The night mode can't overlap with day mode. The night timer will auto skip the hours that is taken by day mode. Please edit day mode timer first.
