  Super Bright, Automatic ease in/out of light.

  I bought a random tank with cool blue led lights, glowing gravel, and with neon plastic plants. Only thing is, the fish freaked out with blue light - not to mention the shock of the light being super bright when it turned on. When I removed the old tank leds, it read, "Danger: Do Not Look at Lights When On." It was pretty bright.So this is very simple to use, and eases into brightness settings, which is AWESOME. It's kinda clunky, but I got it after playing around for 10 minutes. Before I go into the how to, know that it is indeed waterproof, super bright, and brightness can be adjusted; I'm still playing with between 50-80%. The fade in/out happens during time periods you specify.There are 3 modes. Think of them like this. Sunrise to a few hours before sunset (51), Sun has already started to Set to night (52), and full custom (53). Fortunately I only needed 2 modes. Whilst you can set modes 51 and 52 to overlap, it's causes mode 52 to kinda not work right.For me, I needed to use two modes. Some people may just need one, depending on where the tank is located. I need mode 51, as turning on the lights in the house caused the fish to freak out in the morning. I needed mode 52 because the room where the tank is located has blackout curtains, which will block the natural light if left closed.For me, I have mode 51 go from 6am to 3pm. What happens is, the white lights go from 0 to 70% from 6 to 615. Then stay at 70% till about 245, then from 245 to 3pm white light goes off.Mode 52 starts at 4pm and goes to 9pm. Red/Orange lights brighten from 4 to 415, then start to dim at 845, with off by 9pm.Mode 51: Day Time. This is your basic "white" light settings. Think Sunrise to a few hours before sunset - the sun is still up.4 Options. 1) On/Off ( as in used or not used ). 2) On Time. 3) Off Time. 4) Brightness.Cool thing: I set the on time to 12:00 and off time to 12:03 with brightness set to 100%. From 12:00 to 12:02 it went from 0 to 100% brightness, and from 12:02 to 12:03 it went from 100% brightness back to Zero. It seems to take 10-15 minutes to go from Zero to the brightness level you selected; a gradual wake up. Naturally, if you set the on and off time to less than 10 minutes, it turns on at 00, peaks in the middle, and goes off by your end time. It will go from Your Selected Brightness level, down to 0/off in the last 10-15 minutes.Mode 52: This is for dusk colors. Same 4 options as mode 51. The difference is the brightness. Here you can set Red, Green, and Blue (RGB) colors, only up to 50% brightness. There are options for R + G, G + B, Just G, etc. From testing my fish do not like this blue either, even at 25%. My fish were okay with green/yellow, but ultimately I settled on just Red, as the fishies were cool with it.Actually setting it. You Tap the "M" button to cycle through 51, 52, 53, back to clock. When you're at 51-53, you can long press the "M" and that option will start to blink. Use the up/down arrows to change options, Tap "m" to move to the next option. Upon reaching the last part of the option, you're basically back at tapping "m" sequence.Overall I would give this 4.75 stars and not 5. The missing quarter star is for the 51, 52, 53. It could read, Day, Nite, & Cust. However, I only plan on setting this once, and plan on having this thing go for years between settings. It's not enough to remove a full star.

  A Really Versatile Light

  A great light for the money. Compared to the more expensive variety, they do as much if not more. Can be very bright if you want it that way but I run mine at 50% and the plant life in the tank does wonderful. The fish like it that way too. They are set to come on that way and turn to blue light at minimal percent. I do not have to touch them unless I want something different for any reason which I can do easily. A really great value for the money!

  Best Budget Freshwater Aquarium Light

  Decided to try this light on a small wild/overgrown tank.Loaded with features in the tiny little controller inline with the power. Growing plants like crazy in a 20g long. There are some minor limitations with programming, but auto ramping up and down combined with color/spectrum adjustments thanks to the supplemental rgb diodes makes it acceptable for the price.I'll be buying more of these and future Hygger lights for future tank builds! It's not a fluval, but it's the best light you can buy on a budget.

  Complicated but works like it should

  It took a negative rating to be able to have someone reach out to tell me what the issue was. Updated review accordingly. The most irritating thing about this product is that you can’t schedule the “moonlight” to turn off in 53, but if you use 51&52 you are unable to use the brightness/timer features. Misleading at best. I’ve tried researching my own set up and still can’t get the night light to go off until the daylight cycle starts. Basically paid for features that can’t be used. And all night light isn’t healthy for the fish at all.

  Cool lights

  Love the fact that you can program it but not how hard it is to program or the fact that you have to reprogram when power goes out. Wouldn't be such a big deal if it were easier to program.
