Bozily Aquarium Lights LED 300W, Full Spectrum Coral Reef Light for Aquarium Tanks Lighting APP Control with Auto On/Off Dimming & Timer for Saltwater Freshwater Fish Grow Marine Tank

We have two of these lights. One of the lights developed and issue after 9 months and the company immediately took care of me and now I have a new one! Thank you!The lights are very nice - my only issue is the app takes a bit of getting used to. I'd recommend watching their video on how to use it. My first setup had the lights at 100% for each daily lighting cycle. I didn't know you can select your light, then slide back to the settings page to set your brightness/color temperature. Then back to save the settings on the timer page. Now they come on at 50% brightness as we were growing too much algae at 100% due to the smaller size tank.The app also allows you to use multiple lights - so we have two sets. Both are set to turn on/off at the same time and have been flawless on timing since we got them last Oct. The only caveat is they lose settings with power loss I believe. Maybe a UPS of sorts would help.

I received the light yesterday. It is replacing 3 AI Sol whites that have definitely served their purpose. They are over seven years old and even though they still work their output doesn't support SPS and LPS coral growth anymore.So I figure for $100 what the heck I'll give this a whirl for 30 days and if it doesn't work I'll return it.The Pros1) The cost - if this works in growing SPS and LPS in my 50 gal reef tank what a bargain.2) Ease of installation - Pretty straight forward, it took me about 15 minutes to get the light installed. I didn't use the enclosed cables as they were too long.3) Appears to be bright enough but not as bright as the 3 AI Sol units. I am using one of these Bozily units for the whole tank.The Cons1) The app setup is awful. They need to get someone that uses English as a first language to do the instructions. Like almost everyone else it took me a while to get the unit programmed.2 They do not ramp up. Even though they are programmable they do not ramp up between settings. They are steps. For example 7:00 am 25% White/Blue - Noon 100% White/Blue. The units goes from 25% to 100% at noon with no ramping up of percentages in between. Not the end of the world but I would have paid a bit more to have this feature.3) Power cord is too short. I will have to get an extension cord and then have to reprogram the darn thing. Which leads me to my next point.4) if the power goes out to the unit it loses everything that was programmed into it. It needs to be reprogrammed again.5) The unit does not go to the current timed setting once it is programmed. You have to wait until the next setting time for changes to take place. So if it is 3:00 pm when you are done programming and the last thing you programmed was 25% Blue at 7:00 pm that is where the unit will stay until the next step in the program. If you want 100% White/Blue at your current time of 3:00 you will need to set it manually at 100% White/Blue. It will then got to 25% Blue at 7:00 pmIn summery if you don't mind not having all the bells and whistles after one day this is a great unit for the money. I will report back and let everyone know if it can grow corals. I am keeping my fingers crossed on that point.

New update ): not sure if it's my luck or what but the 1st replacment light I received 2 wks ago has blue lights at random areas over the light . Unlike last time an entire section failed. I have fans running lights never run above 50% and top heat sink temps stay about 79.7f across entire fixture.But 2nd replacment i got last week for other failed light is doing very well so far. Not sure if I'll try another light or get refund and move on. Must say customer service has been great. But I'm tiring of going to kohl's every week or so..I will add while mine are great when working 100% they tend to have a high failure rate. My aquarium is on a 20 amp dedicated circuit on GFI surge receptical and a whole house protected panel on 200 amp service and constant 120 120.9 v in a natural gas home so I no it's not a elect service issue. Is anyone else but me having this problem ? Not sure what to do at this pointO.k another update 2nd of the 1st two I brought on Nov.30th last night had 4 rows of all but blue leds to go out. On the panel with switch and elect connection. And the lit blues did not run at full brightness and light fixture was missing from control app. Unplugged did get app back to seeing the light. Been dealing with aquarium lighting For 55 yrs if not longer and LEDs from the 1st Ones known as nova lights.. several types I now own heat is the killer and I was getting over 100f in areas from plug side to far right temps dropped to 94f .Being liberal 90 to 105 plus was found over entire panel. I has a 12v computer fan I put over 1st replacement light I got on dec 13 temps dropped like a rock from 100+ to 85 average across entire top panel I I also took a old icecap ballast heat sink to set on top to pull more heat that lowered temps to just above room to 78 to 80 across panel. I've owned lfs and managed live coral grow operation to bagging and shipping sales. Used every lighting type there has ever been. These leds are good when firing 100% but seem to have a high failure rate so far I hope I just got one a bad one 1st time and a weak one 2nd ?I love the light and slime design but that could be the flaw no fan ornot enough heat sink for proper cooling . Next replacment due friday will get the same fan and old icecaps fluoresce ballast heat sink treatment to give the light a fair chance.. Heat is the issue I'm pretty sure my ambient room is a steady 73f so room is not overly warm and lights hang a good 10" above aquarium of discus at water temp of 80fBut have to say customer service is great and I did by above bozily 2 yr offer if got the amazon extended.Sorry for long review but wanted to be 100 accurate in explanation and fair and what I see as design flaw from lots or lighting experiences. Will edit again as neededRogerUpdate I must say the customer service is great. Requested replacement light Monday afternoon got notice 2hrs. later new fixture would arrive yesterday Wed by 9. It did . I took dead light back to Kohl's tuesday morn. So for customer service I give 5 stars.. new light is working fine my original light is fine. I think it was a popped capacitor on the driver circuit for all leds not blue that let go. It happens.The blue circuit kicked butt still.Ordered 2 lights one seems to be fine . . One yesterday blinked out to only the blue leds cant get white red or green to cut on. Contacted Bozily yesterday heard back this morn . Atleast the replied waiting now to hear back even with free two yr warranty I also brought the 14.95 for two lights extended warranty.. But will say when they worked they were good lights. One at the moment still is. F.W planted tank lights hang about 8" above tank rim . They came on was running head click thought CO2 reg. had come on looked over one end of tank really blue (:

Do not buy this light, its total junk the app to control light is hard to get set up then when you finally do get it set if the power goes out or even flashes you lose everything programmed, now that that has happened cant get app to work at all, lights now can only be used on full power cant dim them and now have to turn them on and off manually, full power light is too much and just causes alge in aquarium.. I even tried customer service and they won't reply.. a total loss of money and a complete rip off of what it says it can do. Junk! I hope you read this before you purchase or you will be the next victim to bozily lights that take your money give you junk then move to the next victim..
