Phlizon 165W Dimmable Full Spectrum Aquarium LED Light Daisy Chain Funciton Fish Tank Light LED Reef Decoration for Saltwater Freshwater Fish Coral Reef (16"x8"x2.4")

I replaced the three 16-inch full spectrum LEDs with two of these 20-inch long full spectrum LEDs. They are significantly brighter than the previous lights put together. Thanks to the adjustments I made to the white and blue light knobs, my tank is now crystal clear. The only gripe I have is that I have to adjust manually from blue to white. Next time around I’d get the auto feature. My tank is 6ftX18inX2ft bow front.

Maybe more of a blog than a review, but hey if you have some time, so do I.I've just stepped into the planted aquarium hobby about a year ago. I've dabbled quite a bit with salt water aquarium before this and decided to try out a few freshwater planted tanks. I experiment quite a bit with different lighting fixtures, water parameters and substrates. One thing I've found, is lighting has a drastic affect on balancing a planted tank. I went down the lighting rabbithole, researched the science behind lighting for plants (and microbial life too!), I tried 5 different lights for my 10 gal, heavily planted shrimp tank before coming across this fixture. Having failed to balance this tank with any previous light (before shrimp were involved for those who are concerned) I didnt hold much hope into this relatively cheap option, but it had the power, and it had the spectrum, so I gave it a shot. After about a week or 2 my plants started BOOMING!! My dwarf baby tears (which almost died off) started pearling, something I had never seen. Soon after, algea started to become a big nuisance. I dial back the output to a little less than half and run the light only 6 hours a day. My plants still loved it and the algea died back with a little help from seachem excel. I still run it on the same output and timing.Being the second cheapest light Ive tried, Ican't hardly believe the results.I've been running it for I think 5 or 6 months now, so far very solid growth.One thing I have noticed, is the dials (which i believe are called pulse modulators) are a bit on the cheaper side, for obvious reasons. They do tend to be finicky when making adjustments and also, probably the reason people report it having a short life span. Though I can't confirm because mine is still in working condition, I believe these could be easily replaced for about $15 per dial and a soldering iron. If just 1 channel goes out, that could be the culprit. In any case, these lights are pretty simple and LEDs don't often "burn out" so any problem presented is likely an easy fix for those willing to troubleshoot.Overall great light, I hope it becomes available again in the future, I would like to use them on my 40 gallon planted breeder next!

Excellent light for growing soft corals....Excellent customer support.

Just set mine up on my 69 gallon reef tank and i'm very impressed with how bright this light is! Like DO NOT stare directly at it with the whites turned all the way up.. it will burn your eyeballs lol 😂I have been searching for a bright "budget friendly" upgrade light for my tank for awhile now and glad i came across this one. It seems very sturdy and well built and i really like the simplicity with the controls. Just two dials and a switch (my dials do not look like the pictures though and have no white lines for intensity measurement, but that's alright with me). I do have a few minor complaints with it, however. As a few others already mentioned in the reviews the steel cables it comes with do seem very thin and i am kinda worried with how well they will hold up and don't even bother with the cheap carabiner clip. I will probably upgrade the cables to something stronger in the future. Also the power cord is super short. Had to get a very long extension cord to even begin to reach the outlet. Other than that i'm pretty happy with it so far! Super excited to see how well my corals grow under it and only time will tell to test it's durabilty in the long run!

Excelente

3.5 stars. These lights are decent, probably ok for the money. I got them as an upgrade to my $50 harbor freight fluorescent shop lights which have been going strong for 3 years, but haven’t been quite bright enough to keep my ludwigia as healthg as I want. I would say these lights are maybe 20% brighter than the shop lights. Is that worth $300? I’m not sure. I was honestly expecting them to be a little brighter. They are absolutely not 150 watts as advertised. But they are brighter than what I had, so I guess we’ll see. The fans are very quiet, but may be noticeable on a small tank. I have a sump with a wet dry filtration system so there’s a bit of running water noise already, so I don’t hear the fans.My main issue is that the outlet on one of them didn’t work out of the box, so I had to put that light at the end of my tank to make the three light system work. It doesn’t bode well for quality control, and I was already worried about longevity of these lights.My other issue is that the outlet that connects each light together is on top of the light rather than in the back. This makes it so that there is a cable sticking up awkwardly from each light and there’s no easy way to hide it.

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
