A must-see for beginners! This light makes my 60cm grass tank look like an underwater IMAX theater. The black technology of the inverted suction cup is amazing – last time I was cleaning the glass ceiling, I accidentally threw the light body away, and it turned two and a half weeks in the air and was able to suck it back! (Don’t learn from my slipping) I especially praise the gradient color design. My clownfish now does a courtship dance at sunrise
Ideal for ensuring that fish have a daily cycle.
Best bang-for-buck light in my 20yrs of guppy farming! The accidental splash resistance is no joke – when my auto-topoff malfunctioned, these stayed dry while my $600 LEDs fogged up. Suction cups grip my warped acrylic lids better than my last marriage (lol). BUT… that timer system needs an exorcism! Last week’s brownout made me reset 35 tanks manually. Pro tip: I hacked it with smart plugs until they fix this circus.
This light looks amazing! I love the day tonight feature, it really adds a contrast to the tank and I enjoy viewing the fish at the different lighting modes. I actually used command strips and attached it to the lid of my tank and it works perfectly. It’s bright and really brings out the beauty of your tank!
Useful & Easy Features:
I have 2 Hygger lights with identical features on separate tanks (one running over 9 months now) and all seems excellent so far. All the lights are still working and the colors / brightness controls are varied and useful. The white/red/blue full spectrum setting seems to help my plants grow while the various other colors are fun once in a while. The timer function is much used and easy as well. Other features are helpful too like auto dimming up and down at start and end of timer settings (which is nice for fish quality of life since the light doesn’t abruptly turn on and off).
Highly Recommended:
All around this light seems solid and useful for a large number of users with many types of needs and comes highly recommended. Affordability is hard to ignore too.
24/7 Natural Mode Very Bright/Long Lasting:
If I were to change one small bit it would be the ability to limit the brightness in the 24/7 Natural mode plus how long it stays on in a day. This mode is attractive because it simulates dawn, midday, sunset, and nighttime lighting. It looks great too and shows fish in a variety of nice looking natural hues. Problem is this mode forces the light to blaze at full brightness for many hours and the whole routine lasts for, I think, 18 hours total. Some plants and fish can’t handle that much light. Also, a lot of light over many hours promotes more algae growth in all tanks planted or otherwise (when having the ability to reduce brightness / amount of time on is a good way to inhibit growth).
Note that it does support control for brightness and a few settings for the number of hours on with the conventional timer mode, but that only gives you one color of light (and not the elegant shifting of natural colors).
The light has a 24/7 function that does a slow sun-up, daylight for the day and then moonlight for a time and off. It’s really very nice and the live plants are growing well under it. The only downside is the instructions on how to set that function appear written by an engineer and then translated to english by an AI bot, but eventually you’ll figure it out.
The bulb in my old hood burnt out so I just pulled that and tied this one inside the hood. Couldn’t be more pleased with it at this point – it’s been running great for a few months now.
I love this light. I stuck it to my fish tank lid and it looks great. The timer is great since I work it helps keep my plants with light and also turn off after 10 hours for algae control. Love the price for a beginner like me. Very happy with my purchase.
This is a great light and I highly recommend it, but I want to know the photosynthetically active radiation (PAR) levels for the 8 inch 6 watt and the 15.9 inch 10 watt.
Hi Bob,
The 8 inch 6W has a 30.6 PAR, and the 15.9 inch 10W has a 35.9 PAR.

Is this safe to use under water in a saltwater tank (refugium)?
From what material are the outer components made (is there any metal)?
Great light so far!
Hi Michael Heinrich,
Yep, the light is made by PC and can be applied to various freshwater tanks and saltwater tanks.
Thanks

Overall like the light. Purchased the 27.4in 16 watt submersible aquarium light. I was hoping for the light to be a little bit brighter. I was wondering what the Photosynthetically Active Radiation or PAR of the light is? Otherwise satisfied with the products function for the price.
Hi Kevin, sorry for the late reply.
The 16W version has the 55.08 PAR value.
Thanks
