Phlizon165W 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!

These lights are very bright, they appear to be built decently well, are quite large, but compared to more expensive lights appear to give me the light output and range I was looking for, just with a lack of a auto dimming/ off function (which I currently just use a smart plug to do ((just off and on, no dimming)), although it is not natural, the fish do appear to get used to it). The hanging fixtures are very long with the lights hanging about 12 inches lower than their anchor point, so I just doubled mine over for my custom hangers and it seems to be doing the trick. Overall I’ve heard the blues go out in about a year so if that happens then that would be the worst part of these lights in which I may go with a more expensive set. However, as a beginner to the reef tank hobby these are very simple, and functional for me right now.Update: 4 months in and with more. Knowledge I would have gone with Kessil lights, for two reasons. Size & longevity. The lights are still running well, some brief almost non noticeable flickering every once in a while but working well.

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.
