This is one of the lights I'm currently using. Each PCB has 25 Cree/SemiLed LEDs, blue, royal blue, UV, red, green, neutral white and warm white for a total of 100 emitters.

What are equipament you used? What board eletronic is this?Built my own lights because I enjoy projects like this. Definitely wasn't cost effective, but my corals are happy and if there are any problems I can easily fix the lights myself. In general though, the DIY LED scene is pretty much dead.
I have built a few DIY Leds for older systems (been since 11') so familiar with them. Back then did meanwell drivers and 3w Cree . I know I did not have a good color ratio. Please let me know what LED's you used on your larger system and the ratio. TIAI still do.
Both home and office tanks run on diy leds.
(Some details on the led build Post in thread '15g Office nano tank - natural sea water' https://www.reef2reef.com/threads/15g-office-nano-tank-natural-sea-water.820995/post-8825471 )
I think you can save money if you know what you are doing and if you accept some compromises.
My home led cost less then 400usd (probability around 300) and give me even par of around 300 in the middle of the tank using about 140w. Tank is 4 feet long, with very litle shadowing as the led are distributed over an area of approximately 100cm by 30cm.
If you really want to get fancy you can have your own pcb made so you can have multiple chanels for control
The office leds are just on and off (although they can be easily modified for dimming) while the home ones are controlled by the ghl.
Cheers
Hi Reign.I have built a few DIY Leds for older systems (been since 11') so familiar with them. Back then did meanwell drivers and 3w Cree . I know I did not have a good color ratio. Please let me know what LED's you used on your larger system and the ratio. TIA
what wattage are each LED?Hi Reign.
They are a mix of (supposedly) epileds, bridglux and a lot of cheap 3w led from ebay. Can't really confirm the origin, but while they were sold has such I suspect most are cheap chinese leds. Having sait that, the lights have been going for 3 years and apart from replacing the uvs (they burn out easely), it has been fantastic.
The couler mix is about 13 whites, 3 warm whites, 8 to 10 around 400nm to 410 and the remaining (58) are mainly royal blues with some different shades of blue in the mixe.
There used to be below 400nm but they keep burning out, so I replaced them with 400 and 410nm from ebay.
Current state of the tank
Cheers
3w but ran at less then 2w eachwhat wattage are each LED?
