The fixture is made by a mysterious company named LJY. The product is listed as "LJY Hydroponics Red Blue LED Plant Growing Floodlight Lamp IP65 Waterproof AC 85-265V (20W)", and the link is here (http://www.amazon.com/gp/product/B00M31GHIS?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00). I bought two of the 20 Watt models, they also sell a 10 Watt model. Stock photo Actual Photo (sorry don't have a great photo, but it is identical to stock photo) Claimed total wattage is 20 Watt. This coming from a multichip LED with 16 reds (660 nm) and 4 blues (445-450 nm). It claims to be waterproof (IP65 specification) but I am not about to intentionally test that There is a stand that is adjustable. And a really good heat sink on the back. This light does not get hot after continued use. I can place my hand in front of the light after it being on for several hours. It is warm, but no where near burning. I could hold it there indefinitely. Useage: I started a thread detailing a DIY scrubber build here (My DIY, PVC ATS w/ LED's). This thread has much more detail. System flow is ~245 gallon per hour. Screen size is 6" x 6", lit on both sides. Scrubber is 3" wide (inner width), so the fixture is approx. 1.5" from the screen. I am still in the beginning stages, but I do have algae growth. I began by running them for 16 hours (approx 2 weeks). I scaled this back to a 12 hour photoperiod. At Turbo's suggestion I added a light diffuser to help spread the light out a bit. The growth in the center of the screen is/was being hindered (too much light). I'm still new at this so may make more changes yet to improve the success/establishment of algae on the new screen. I have not cleaned the screen, but I have taken it apart 2 times to check that the slot is clear. I did scrape down the smooth part of the screen to discourage growth. 9 Days Growth (at 16 hour photoperiod, no diffuser) 3 1/2 weeks growth (scaled back to 12 hour photoperiod and added diffuser at 2 1/2 weeks) 4 1/2 weeks growth Preliminary conclusion: I'm happy I purchased these lights! For what it's worth, 2 of the 4 reviews on the Amazon page are from people who use them for an ATS... I'll try and keep posting my progress.
