hygger 30 Watts Aquarium LED Reef Light, Dimmable Full Spectrum Marine LED Fish Tank Light Saltwater Nano Aquarium LPS SPS Lighting

Works great for my little 15 gallon! Good options for light colors and doesn't get to hot. Was sturdy and easy to use, great value.

Great for my nano 20 gallon reef. Has good brightness settings with a built in timer on the wire so no need for a remote. My corals have thrived just fine with this light and I'm very happy with it for the value.

Easy plug and play reef lighting. Coral seem to be doing well under the light. Wish it had a little more par but for the price it's nice !

If you are unsure about this light for a pico saltwater tank just buy it! we currently have 2 of these lights, one on a 2.5 gallon Pico, and 1 on a 5.5 gallon Pico. PAR readings are super fantastic and easy to work with coral growth is beautiful. I easily hit three to five hundred par on my 2.5 with light about five inches from water. Light is 6 inches from water on 5.5 and gives reading from 300 down to 75-50. Timer works nice these readings are at full brightness with white and blue.

Worked really well in a refugium. I like that it was easy to adjust. Stood up very well in a saltwater system. Didn't have any issues with it shorting out because of the salt environment.

If you’ve read any of my other reviews, you know I’m a Hygger fan. I am particularly happy with this light. For my little 10g desktop tank this was the answer I was looking for. Very, very simple to operate. Not a lot of fancy programming (like for my big tanks) and best of all, an anemone that was stressed out and hiding at the back of the tank, came out within two days and is now open and getting back its color! This was exactly what I needed!

I originally got this for my small 5 gallon tank, it worked perfectly, corals happy, nems happy, great coverage, just wish it had an easier way to tell how bright the light was on. Once I switched to a 20 gallon tank and got a second one they don’t seem strong enough even with 2 of them. I like the ability to move the arms around if I need to adjust it, it doesn’t fit well over a standard tank lip it’s awkward and falls if you move it wrong. Cord length is nice. I wish the timer was a bit better, I don’t want it turning back on after 6 or 9 hours when it’s set to turn off after that amount of time but I also don’t want it on for 12 hours.

I purchased this light for my 33g long Freshwater aquarium. I love the way the reef lights make an aquarium light up in the dark, this is a perfect addition to the moon light phase of the lighting cycle I have setup. Many Freshwater fish have a metallic shimmer and it can be seen best under this type of light. These are three light modes, full Blue, Blue/white, and full white. I find the full white mode useful for doing tank maintenance and just generally having a bright light available to see things.

Update after a few months - i reduced rating to 1 star because: 1. it requires a manual re-start each time i am on vacation and there is a power failure or if i try using a timer, each time it stops needs to manually press the button. This is not usable for my reef tank refugium 2. The fan corrodes in saltwater environment and is already useless after a few months. The fan stopped and started smelling burnt, i kickstarted it temporarily and hope it works until i receive a new refugium light that is made for this purpose. 3. The light frequency is not well tuned for growing macroalgae at a fast enough pace to properly export nutrients in my sps reef tank Using it in my reef sump for macroalgae and some bubble tips.
