So if you used on puck would that be enoughchannels are in the 20-30percent range. this light would cook this tank full out

yup the psu was dropping voltage as it got closer to its peak (cheap chinese unit) the channel that went out was the one pulling the most voltage (45 needed to run at the ma raiting im running it at) so that makes sence that one wouldn't go. once I added a second psu to power half the ldds it runs fine. going to get a decent 250 watt meanwell unit to replace the 2 150/180 watt psus i'm using nowThus happens when an led driver is not withon its voltage efficient voltage range, look up the data sheet for the driver. It will list its peak efficiency, which does have an effect on dimming. I usually see this when a channel is running above its efficiency range, the led driver doesnt know how to compensate.
yeah for the 20in cube yes I think it + a couple limes/mints would be perfect.So if you used on puck would that be enough
ok got it over my 20 and now that its working this is my first fully adjustable led spectrum setup. to my amazement i'm starting to buy into the whole you don't need white anymore argument. right now i'm REALLY liking the look of just Violet, Royal Blue, and Mint. nothing else running. its a bit "blue" but its whiter than I thought it would be.
Just RB/Violet/Mint
sounds like they want 32 shipped for it. and i was wrong it was a 4x4 boardI would like one or two of those arrays for sure.
Kampo I went on topledlight.com they have all kinds of boards I don't know what would be a good mix could you take a look and give me idea witch one would be bestsounds like they want 32 shipped for it. and i was wrong it was a 4x4 board
8x450nm on 1 and 4
2x4k, 495nm and 470nm on 2
2x395nm 2x420nm on 3
for the money the board i just used I think is the better buy. but this would be nice since it can be fit in a tighter package. debating what i'm going to do for my frag setup now. I have 2 Blue Acro half Pucs I could just go with. planning on a 20Long frag tank i think 2 pucs should be good. I have 2 12v actnic suppliment bars I might just add to the fixture to give a little more boost. that said i'm super tempted to get a puc like above to build a nano light for work, giving me 3 blue acro pucs for the frag tank
I really don't want to just recomend something becauase there are so many ways to go, pros and cons to all of them. options to look at:Kampo I went on topledlight.com they have all kinds of boards I don't know what would be a good mix could you take a look and give me idea witch one would be best
High wattage LED coming from one point will likely burn what ever they are focused on, the safes way to create the singke ppint effect is ti have all the leds under one single wide angle lense... like kessil or some of the knock offs out there. There is a new thread on black box leds, the last one posted k7 led.Does anyone have any thoughts what lumen output would be needed to create light beams in the water with some surface agitation? I was looking at the Cree 30W-100W LEDs as a point light source to create the effect. I just don't want to harm any corals.
That was my concern. That's why I was looking at mounting the high wattage LED in something like this.High wattage LED coming from one point will likely burn what ever they are focused on, the safes way to create the singke ppint effect is ti have all the leds under one single wide angle lense... like kessil or some of the knock offs out there.

The leds are at thier widest angle with no lense. Its rare to find a 60mm wide angle lense 120 degree minimum, as most 60mm lenses are focused on automotive use. Im pretty sure if you do enough digging you will find one.That was my concern. That's why I was looking at mounting the high wattage LED in something like this.

Which, admittedly, has a focusing lens, but I can't imagine it would be too hard to buy a wide angle lens to fit.

So how do they compare to the name brand lightsWorking on the morning. Not perfect yet but I'll clean it up a bit more wanted to see if this would work before I bought some hardware to mount it better. Doing a test at 80percent power with both fans now.
Only downside of this is its a bit lower than I'd like and its about 1.5 inches further back from true center. I think this will be ok. most rock work is in the back of the tank. sandbed is usually lower light stuff. but not sure.
wider picture for scale. yeah it messed with my camera sensor BAD
I would say since i've personally never had anything but DIY over MY tanks I'm not the best to ask. I would say spectrum wise equal to better than any name brand. easy of use prolly better than some worse than others. I don't have any real testing to base my spectrums arround so i'm just guessing. i'm going to see if I can borrow a par meter before I really get this tank going and dial it in a bit better. that said. I noticed a lot of corals perking up under the increased light when this was over my 20 cube. that tank is back to its old light for now.So how do they compare to the name brand lights
Any update on your light?I would say since i've personally never had anything but DIY over MY tanks I'm not the best to ask.

very pleased with the build overall. will continue to update as my build continues. I really need to get the plumbing done so I can move forward.
Could you post photos of how you wired your drivers, power supply, and controller? I'd love to see it.And I'm wiring it up. Hopefully can get it going today
