Calling out to Weezard for LED advice

[luc55]

Hi guy's been reading, and figuring, and reading, for a couple weeks now. didn't want to open my mouth just to ask questions. This is the best LED thread on the net. ledengin seems the way to g,o but I just found another manufacture ShenZhen Romanso Electronic Co., Ltd does anyone know anything about them or their leds. they sell for 98 cents per watt but they have leds up 100w I'm having trouble getting excact info Me thinks language barrier, to cover430nm 460nm 630nm and 660nm Libby said it would be 8 leds without being specific.
In order to get wavelength info you've got to contact them (Libby)
anyway i would like to make a light with 1-430nm, 2-460nm, 3-630nm, 6-660nm, 4-680nm total 16 leds X 10w
any comment on the wavelengths power sup. or reg. are all appreciated.
and for a power supply fleabay has a Meanwell 350 clone $45.us {15V DC 23.2A 350W Regulated Switching Power Supply}
also plan to regulate individually or in groups with LM2596 LED Drivers Current/Voltage regulator PCB adj out, $4.25 us with shipping
BTW Weezard your #1 guru in my book. and how was the wave from Japan?

I would say if you want to use another manufacturer and there are hundreds in China then you would want to talk to someone who has used that specific one. Or order your own samples. I would go with something tried and true if you are going to have any type of expectations from it.

I am actually working with a similar manufacturer on a multi-band 100w multi-emitter package. It's difficult, though. Getting my desired ratio and in a specific pattern is somewhat of a nuisance because of varying voltages across each serial string. I may have to stick with a different pattern with a more uniform configuration than spread out.

I've seen a plain 100w one, and they're pretty intense, especially on the quantum meter.

I have already built a "hood" of sorts. I'll get that and the rest of it done tomorrow.

All red.

the j-light 115, heh, no plans to commercialize, its a joke

10" high with the shroud (one power supply is the rail mount kind and sticks way up)

8.5" wide from the front and 6" deep

2" of shroud hang below the LEDs

The screamin' bright, J-light?
Outta sight!
May your gals grow fat
an' your buds be tight.

Thanks for the photo's.
Any advice for the next DIY guy?

Aloha nui techie.

Thanks Weeze. You are awesome. You too Khyber.

Advice: Read a lot, learn to solder, plan, do.

I have some Jack Herer clones ready to go. They get da purp treatment starting today. I will have more pics later once everything is set up.

And thanks to DH for starting this thread and everyone who contributed.

Looking great! So glad you bought pre-mounted LEDs because let me tell you IR or oven reflow soldering is a PAIN.

Thought I would stop on by and see how things are going in the LED world... I read this article today and it made me smile. Future farm: a sunless, rainless room indoors - Yahoo! News

I wound up going back to a HPS setup because my led's didn't cover the footprint I needed. If I ever get around to building a light like Weez or DH I'm sure it can be done.

Revamped and redesigned. Now it's 125W and hung from a single chain. No reflector and down to a single PSU.

I like the CFL to make it easy to see and hopefully add a spectrum or 3 the plants need if they do. It's a 42W (true power) ProLume, but it's almost 3 years old now.

Those are 6 F1 Jack Herer clones. They had their first 12 hours of dark last night. Day 1 today.
