WILLSAquarium Light, Full Spectrum Reef Lights for Coral with Dual Dimmable Channels, 55 Premium SMD Chips, Daisy Chain Design, Hanging Saltwater Fish Tank Light for SPS/LPS Coral Reef (165W/Black)

This is my second purchase of Wills lights. My first set is going strong without any issues for ten years now. The LEDs are very intense with excellent color saturation. I'm an old school aquarist so I'd much rather get off my lazy butt 2-3 times a day to adjust the colors for feeding time. The whole point behind having a good reef tank is that you're supposed to enjoy all you can see and the Wills lights fulfill that need well. I strongly prefer this over having to screw around with the lackluster app I got with the Current Loop System (a month ago) and I deeply regret that particularly overpriced set of lights which is why I went back to Wills lighting. The only down-side for me is the bulk and weight of the item but a good suspension system will ameliorate that. Well worth the reasonable price.

Works great. Quiet, easy to hang and install. Love the ratcheting pulley. Easy to lift or lower to adjust to needs

Good value, no frills, plenty of intensity, good color, tested w spectrum meter and par meter.

+ It works well and give more light than my 6 year old blackbox did as new.+ The fans works with very low noise.+ The overall constuction as well as the organisation inside fells a lot better than earlier model.+ The led drivers are at 2x50W, my earlier models had 2x70W, despite this it gives a lot of light.+ The new smd 2835 chip are more efficiant, just as Wills says. With blue channel at 50%and white at 75% it gave 7000 lux at 50 cm distance,My earlier model gave 6200 lux at 100% on both channel as new.+ The smd mount combined with less power reduces the heat problem.- The light spectrum is not quite what I wanted, but I knew this. There is a lot of blue ligth at 460 nm,but very low amount at 410-440 nm witch is importent for chlorophyll A. It would have been good ifWills had put in royal bleu and more white instead of 27 blue at 460 -470 nm.- There seams to be more difficult to switch smd diods compared with earlier model.- If you gonna switch diods there is less colouroption to choose from.- There is no extra heatsink construktion like Vipaspectra has.

Very nice lights for the cost. Better than many other lights output. I had to make a way to hang them

As much as I love the brightness of this, I'm not a fan of it. It tends to get stuck on the setting it's on and won't reset until it is turned off for at least half an hour to cool down. I never run it at full brightness.

Its lighting potential lives up to the ad. Its turned not even half way up and its as bright as my two 30 watt lights. I had to send my first one back. I had it turned up on high right out of the box and the potentiometer failed in short order. It took a week for my refund but i did immediately order the same light.This light doesnt have a built in timer or ramp up and down lights but i put it on a timer at the plug and it comes on after my other lights have ramped up and goes off before the lights ramp down.I was getting about a 110 par at the bottom of my 55 gal tank which is ok but not great with my two 30 watt lights but now i can definitely hit 175 maybe 225 par with this Wills light. With LEDs i believe to be beneficial to may corals, soft corals and inverts as well as keeping the fish happy. As it is now i say i like this light very much.

I purchased 2 lights. I am down to 1 light. My original purchased was in March 2023, in Aug 2023 one of the lights has now had its blue channels stop working. Support window closed June 2023.These lights were nothing amazing but did the job, and the customizability with the knobs was nice. But for 5 months and to break, I just don't feel I even got close to getting my moneys worth here.
