kevreh blondskeleton,

I have a smaller tank with a 14"x14" footprint. Already have some leds and a typhon controller. Need to spend another @$50 on meanwell ldd's and a power supply.

With that size tank I only need about 10 leds. Talking the 3w endorstar ones. Problem is, I'm concerned about spotlighting and the disco effect. (btw, very nice led tutorial you wrote ). I can buy a fugeray planted+ for about that amount. The fugeray and current lights use a lot of smaller leds to address what Im worried about.

What do you think?

Glad to hear it, sumer! I completely agree with you. I love this thing!

Probably it can be made half price in Hong Kong But really nice work. I love that hanging arm.

Just the cables are luttle bit messy but no one look at under the fixture. And no one can see when lights are on even they look at that

Anyway eventually i like whole thing. Good job my friend!
Haha, thanks, Gecko! Expensive, yeah! With O2Surplus' SmartyCat and sink's code it does exactly what I want and I have complete control over every aspect of its output, so I think it's worth the extra expense. It helps me to understand light better when I can fine tune it. That's something you can't get from Hong Kong

I admit my wires are messy, haha! Thanks for checking it out!

Haha. No kidding I managed to blow out channel 5 (totally my fault) but it works like a champ!

and after your experiment what do you recommend for the ratio between CW and NW
Thanks! I can't say how much I love the heat sink. It's a pretty well engineered package.

I'm running 36 emitters now (after adding the 8 warm whites). My driver is the SmartyCat designed by O2Surplus (see his thread about that). As I recall, it runs at about 1100 mA, but I have each channel manually dialed down quite a bit. I couldn't say exactly what the current is for each channel, except to say it provides plenty of PAR without algae issues.

As for the ratio of cw/nw, I'd say add the warm whites to the equation. Without them I was getting leggy growth that looked like I just didn't have enough light (which I didn't in the red part of the spectrum). My current ratio is (cw:nw:ww) 1:1:0.5, but my cw are running at about 75%, my nw are dialed down at least 50%, and the ww are running at nearly 100% (of the 1100mA max). They also have 80 degree optics instead of 60 degree optics like the cw/nw.

In other words, a lot of variables going on there.

I'd almost say you don't need nw, except to render your greens. That would be a personal choice.

Those are just my observations based on my conditions, so things may be different for you. Hope that helps!

What are you using for a power supply? I bought one on their site, but I am not a fan of the exposed line voltage terminals.
I'll have to check out the hanging kit - I have a decent setup for it right now, but I do enjoy tinkering.

I have the Meanwell power supply as well. I'd be more comfortable with it in a box, but it does all right.

I had blues for a bit, but I was getting crazy BBA with them, so I removed them. I have enough blue spectrum with the cool whites to keep the plants happy, so it didn't bother me too much.

theblondskeleton I have changed this recently. I was running 50/50 (14cw 14nw), but this was lacking in the red part of the spectrum. I have added 8 warm whites to make up the difference, and it has balanced it out pretty well.

kingdave What is your ratio of cool white to neutral white LED's?

That's good to know, Hoppy thanks for the tip! I think I'll drop that in the FAQ...

Thanks! I don't recall what current I'm running right now, but at full power, it'd be burning 84 watts or so (I'd have to double check my specs). Under half that of my T5HO's. I don't run it at full power, however. Turns out it's a lot more light than I anticipated! I need to get my hands on a par meter to know exactly what it's putting out.

The tank is an ADA 120-P, which is 65 gallons (48x18x18). At the current height and with 60 degree optics, it has pretty much perfect coverage, with the most concentrated beam covering the full footprint at substrate level (plus a few inches).
