WILLS Aquarium 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)

Easy to use, clear color crystal clear lighting. Lights our reeftank magnificently! We have 2

great light bought 3 of them one at a time, one each for 3 30 gallon tanks, so i was impressed with light for the price and they really light up tanks. but the third one i ordered had shorter hanging wires and screwed up my plans for my aquarium scene. Lucky for me i only used 2 wires to hang lights on a curtain rod instead of ceiling so i had extra wires of correct length. want to order 2 more and hanging from another curtain rod. thinking twice but then again if one of the two are the correct length i should be good.

Just over four years of ownership and this does the job for a 24 inch deepcoral reef tank. However, because the chassis is made entirely out of steel, it rusted like you would not believe. It still works, but I got to the point where I was afraid to touch it for fear of it dropping metal flakes into my tank. I liked the adjustability of the intensity and colors so you could dial it in to get it just to your liking. I have two of these interlinked which was a nice feature. These are generally simple and easy to use. I just completed scraping them down and spraying them with rust Reformer to see if I’ll get one more time out of them before they completely rust apart. On one of them, the fans stopped working, but that did not seem to impede the ability of the unit or cause it to overheat.

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.

Excellant product

+ 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 if Wills 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.

Strong led light but not the best option for a reef set up. Had issues finding a way to mount light and also to find the sweet spot between par and intensity was difficult.

large and powerful, good value for the price
