Phlizon 300W Dimmable Full Spectrum Aquarium LED Light Fish Tank Light with Daisy Chain Function for Saltwater Freshwater Coral Reef Fish Tank (28"x8.5"x2.4")

This light seems well made, bright, and I found the fans to be quiet and efficient. They're not on any kind of thermostat; when you turn one of the channels on, one of the two fans comes on. Turn both channels on, and the second fan comes on, too. To my ears, they're very quiet. I'm really hearing more the rush of air than I am any motor noise.My only complaint is that there are no purple or UV LEDs as advertised in this fixture. The LEDs on the blue channel are all exactly the same, as far as I can tell. They're all exactly the same shade of blue.In light of this (ha ha!) not sure whether I'll keep the fixture or not. Might rent a par meter to see how much light is actually reaching the bottom of my aquarium, which is quite deep (24").

Mis à part la livraison merdique (il ont laissé ça dans l’escalier avant de la maison, même pas capable de le mettre sur l’a galerie) je suis très satisfaite de mon achat fonctionne parfaitement

Excellent light for the money. I turn the white LEDs to minimum, it would be better if it comes with more of the blue ones but still it’s more than enough light. The wider dimension gives it better coverage than the competitors. You can get away with just one light on a 36” wide tank by placing less light demanding corals on the corners. After watched the black box LEDs review from BRS with the concern on the inferior power supply catching fire, I was pleasantly surprised to find out it comes with a CE approved power supply in its own enclosure inside. The two fans produce some noise but keep the light very cool. It ships with only four wires and hooks, not enough to hang the light right out of the box but a trip to the hardware store and $6 solved the problem. Love the bright and sharp color of the LED, color mixes very well, no disco light effect. The only place you’ll notice some separation of color is in the edge of the dark shadows. Corals show much more color compare to t5 specially in the green and red spectrum. So far the corals seem to like it. I would recommend it

It's not as bright as I hoped, My 300W viparsepctra started dying a few months ago but was brighter than this.Unfortunately, they aren't selling it anymore so I had to look for a new brand.This light uses 239W 2A When both white and blue LEDs are set to their highest setting.I don't have a PAR meter on hand at the moment but I do plan on getting one in the following weeks.I will update this review with those numbers when I get one.For now, It has been installed in my setup, hopefully, the corals will be happy with this new light.I will give this product an overall 3 stars until after I can properly test the PAR and see how the corals grow.The fans are really quiet so it gets a 5 in that.My current setup is a 20-gallon long, Blue set to 100% and white set to 10%The bottom tank is a 20 gallon tall its connected in a similar way to a sump but I am using it as a second tank with its own corals.This is a fairly new change in my set up.This second tank has a 150W Nicrew light with Blue at 20% and white at 10%It is pretty bright, but much like this light I haven't tested the PAR levels either.later on I will get two of the same corals from my LFS and place one in each tank and compare the growth.I will try to get both of them placed in similar PAR ranges.

I bought 3 of these for a 6 foot long tank. The spread isn't big so if you have the light not far above the tank I'd say the 21" light spreads to about 24" at 2 feet depth.Seems quite powerful and the spectrum can be adjusted a bit from blue to daylight.There are far better reef lights out there if you have 5x the money to spend but to get going it's a pretty decent light for the cost.Time will tell how long they last, nd customer suppor, that's where the actual value will show.
