I rarely do the "learning-lesson" thing, but i figured I'd share a failure with you... So back in may, i purchased 4x 32" panels for my 7ft long 265 gallon reef tank. I just spent 3500 on the marineland tank and stand. 1500 on my chiller. Another $1000 on rock and sand. $600 for this dolphin pump, $500 for the fuge, add plumbing, all new test kits, and everything else... and i dropped a chunk on getting my tank up and rolling. The only piece i really didnt want to drop a ton of cash on are lights. especially when i see US companies rebranding chinese LEDs and upcharging 50-100%. (i wont mention them) I didnt want crap either. So after searching for reviews, looking on youtube, and everything else. I thought the most bang for my buck were some DSUNY turing series lights with a programmable controller. For a mere $900 shipped, i received my babies and chucked them in my canopy. They use the 3w bridgelux lights and are spaced a little further than what I'd like with 45 diodes per 32" panel. I set them up lengthwise 2x2. the programmable controller panel was cool and seemed to work out just fine. lightning was cheesey. clouds just dimmed the lights 20%. k...but they ramp blues, whites, and actinics during however i wanted. I didnt need a controller like my 220 MH/T5 setup with an all or nothing approach. For the first 30 days everything seemed fine. no issues. 60 day mark i noticed that when a programmed point was hit, sometimes all the lights would go 100% until the next programmed marker. I would come home to some toasty corals. This happened 3x the 2nd month in. on the 3rd month 2 channels from panel 4 died. only the blues and actinics worked. i contacted DSUNY and they offered to replace the panel for 1/2 off. at $120. Thinking this might be a fluke panel, i coughed it up and replaced the panel. 30 days later panel 2 went 100% on and doesnt respond to the controller. all or nothing. again... contacted DSUNY. offered a newer panel at $125. at this point this is becoming a joke. also i was fighting a dino outbreak so i just let the panel go 8 hours on. then off on a timer. fast forward another 60 days. Panel 4 that was replaced completely died. no all on, no nothing. just dead. 30 days later. panel 1 starts flickering white channels. (yup... on it's way out) lets keep going til now.... panel 1 now has 2 burned out channels panel 2 is still 100% all or nothing panel 3 works as intended panel 4 is toast which lends me to advise you of this. these are worse than a chinese black box. and a heftier premium for them. some other interesting notes about these lights.... Each panel has a 90w driver.... not even a 120 like the old style black boxes. The heats sinks are not enough without a fan. (They have none) Overall I give these lights a 4/5 stars for terribleness.
