Review: 7 month mai light puri tarah kharab ho gai keval adopter mai light on hoti hai time nahi aata blank display aati hai
Review: Yes, programing can be tedious. Take your time, be patient with the directions and yourself. If you choose mode 53 (DIY), make sure you turn OFF the other two modes. Being able to ramp up and down the intensity (& color) on a schedule is a feature i've wanted for years. I went for a gentle warm white fade up in the morning, then a couple of hours a bright white mid-day, and a progressively more red shift as the fadeout works into the evening, finishing the cycle with a couple of hours of 10% blue-only before going off completely just before midnight. The quantity & quality of light is truly amazing for fresh water. I haven't had a salt tank in years, I can't really speak to its blue output being appropriate to make a salt tank have that gorgeous blue/uv pop!. This IS a wonderfully flexible fixture for the cost. We shall see how well its holds up longterm. The only two 'Cons' I see so far, the shortest of hiccup in the power will clear the clock setting, it holds the programing, but not the time. Makes me ponder putting a very small computer style UPs on the aquarium. Lastly, the brackets holding the light over the tank make me a tiny bit uneasy, if younger children interact with tank, or if you live in an earthquake prone area, in just my opinion, its possible the fixture could end up falling into the tank. Perhaps its not meant to be used on an open-top tank, that said, I may put a piece of plate glass under the light. Both of these topics are mentioned in the instructions. In short, for the money, its such an amazing light! ..even for uses beyond an aquarium. I am very pleased with the purchase.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by A***N on 6 February 2025*

This is my favorite aquarium light. I have bought three so far and what I really like about it is the programming I have had other lights that you know you can kind of program to 12 hour length of time, but then it becomes kind of randomized as the 12 hours kind of overlap anyway hard to explain. This one you said it to what time you want to turn on what strength you want the light to be what time you want to turn off what time you want the moonlighting to turn on how strong you want that to be and it’s slowly turns on slowly turns off And then you never have to touch it again. It’s awesome. I like that. It’s full spectrum to help my plants. It’s very high-quality pretty easy to understand the first time I tried to program my light. I kind of stumbled through it for a little bit, but I’m on my third go now and it’s good. One thing that’s nice is if you unplug the power source and then plug it back in it does not erase what you programmed
