Hey DH I hope you're doing better and it wasn't anything too serious.Quote:

That is one good working light if you managed to have only a 4" growth spurt after going to 12/12! And I feel your pain anytime I have a plant over 24" in my partnered grow. We had damn 4' suckers from the SS mom grow out, how people grow that tall on a regular bases is beyond me.
You didn't ask but I'd lean towards using buuba-ponics, much cleaner.
:thumbsup:
If I had time to dial it in, I've always felt the absolute state-of-the-art would be aeroponics , probably a setup very similar to what you've talked about.Quote:

But my hobbies, frottage and mopery, are so time consuming! And introducing myself to all the neighbors (it's some silly court-ordered thing) really takes a chunk outta my day! :D
....ROFLOL :D
You really are busy. Maybe between your walks and rubbing you could dial it in! Sorry to hear about the court order. :wtf:

Badaboom!
Weeze.
Weez and DH,
I went through and read this entire thread again! It took me quite some time and a few beers. Here is what I have as a shopping list so far.....please let me know what I'm missing.
1. Six (6) LZ4-00R215 LedEngin 660nm Emitters
2. Two (2) LZ4-00B215 LedEngin 465nm Emitters
3. One (1) 12"x10.125" Heat Sink (Ebay Guy)
4. One (1) PLN-60-12 Mean Well Power Supply (Red LED's)
5. One (1) PLN-60-15 Mean Well Power Supply (Blue LED's)
6. One (1) 120mm Axial Fan
And of course wire and epoxy.
I do have four questions...
1. How do you power the Mean Well's? Is it just an AC cord plugged into an outlet?
2. Is the dial on the Mean Wells what controls dimming?
3. Do I have the right model driver for powering six reds?
4. What powers the fan?
I think that about sums up my post right now. With your answers I can then order the parts and get to building! Thanks in advance for the help!
Aloha, ledtime,
DH is the goto guy for meanwell info.:thumbsup:
But, if that "60" is the wattage? No.
6 X 15W. = 90W.
Best to use a 120W. supply for a 90W. load
I can tell ya that the fan is probably 12V. and can use the Red led supply.
I usually just use a cheap 12v. wall wart for the fan so I don't cornfuse the current limit supplies with an inductive load.:confused:
I do advise polishing the heatsink to a goodly shine and using good quality thermal transfer epoxy. The life of your leds depends on it.
Now, go beat that credit card like a red-headed stepchild. :D
Como mai.
Weeze
No credit cards for me....Been through that mess once. Never again. Funny, I am a red head. HA!
I'll wait on DH's response on those Mean Well drivers...
You think the heatsink has a big enough foot print? I want to cover 3'x3' and still get decent penetration.....
Weez,
Looking over some of my "notes" of this thread....
Does adjusting the voltage on the Mean Wells serve as the dimmer? I took what you wrote to hermie as you have to dial in the driver at the proper current and you adjust the voltage on the driver to dim them. Is that right?
If that's the case, and I use wall warts for the fans, then the only other thing I need to know is how are we supplying power to the LED drivers?
I guess I need some sort of bench supply to test those LED's...
Okay:
4 -15W reds on a 60-12 is a match made in heaven! :angelsmiley:
Or even 3 -15's, if you're really pushing them.
I'd use 2 60-12's and use 8 reds. But do you have a bench supply? You want to be able to test the leds by running them up to 1200-1300mA each, and see what voltage it takes to push each individual led there. I make a little table and measure:
led #1 red:
10.3V gives 1.1A
10.4 " 1.1
10.5 " 1.2
10.6 " 1.2
10.7 " 1.3
10.8 " 1.3
10.9 " 1.4
11.0 Didn't dare push harder, gets expensive! :D
So this led'll be happy running at 10.6 -10.7V.
So, if you've got a bench supply, you can power up to 7 reds with it, and use it to match up your emitters while you build the light. :thumbsup:
If not, you've gotta guess where to set your voltage, so you wanna be more conservative.
Lemme know and we'll proceed from there.

1. How do you power the Mean Well's? Is it just an AC cord plugged into an outlet?
Yep. They come with a short 3-wire pigtail. Need to provide a supply cable, or at least the AC plug. Got a pic or two I'll post for ya, explains the coding.
2. Is the dial on the Mean Wells what controls dimming?
Sorta. there's 2 little trim pots inside. One controls voltage. I set that where I want it, under load, with the other trim pot (the "dimmer") up full. Then I turn down the dimmer pot until it just kicks in and starts dropping the voltage. That sets the current max so your leds will stay well-regulated. I leave the plastic covers off mine so I can adjust them, and since I do that anyway I put little heatsinks, CPU coolers, etc. on the heatsinks in the Meanwells.
3. Do I have the right model driver for powering six reds?
Talked about that already. Mastech makes a great power supply for ~$165 shipped. Model 3010, up to 30V. Highly recommended. If not, I've got some data on real-world measurements of the 15W's so we can get a safe guess where to run them. But you'll want two 60-12's if you no got bench supply.
4. What powers the fan?
A single 120mm computer fan, ($5) running at 12V. will cool your light jes' fine. I like things quiet, so I run 2 fans at 9V. (One would prolly do it.)with wall wart adapters. Power 'em off separate supplies for backup. Wallwarts are cheap. Led drivers, not so much. Using led drivers to power fans is jes' a waste, I think.
Weezard has used thermostatic switches to kick fans on and off. On lightweight lamps the start-up torque gives you a free mover. Lotsa possibilities. Are you mounting the fan flush against the fins, like the Procyon?
Hey, I see your new post while I'm writing this...
Get a mastech, you can run all 6 reds with it....
