LED grow lights... input please.

Resistive losses in the wire will be negligible unless you're stringing your arrays rediculously. If you manage to make it noticeable, all you'd have to do is slightly lower that chain's resistor's value.

Curiosity Reviewed by Curiosity on 05-16-2006. LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.

knna: good info on specific numbers. This should be helpful to anyone who is serious about this.

dunno if this has already been linked

it could work - but I'm sure the fuckers would have to be VERY close to the plants - I'm all for it though
I love LED
ah...... the photon light raver days

dig this shit up.. so anyone trying this.. i only read the posts thru october :-p

So fluorescent is better for blue light then? I still want my red leds though. Any suggestions on which brand of fluorescent to get? I think I can pick up a few red traffic lights from somewhere.

Yes, at actual led's state of art, blue light from floros are cheaper and more efficient.

Any high color temp (K) triphosphor is valid. 6000-6500K works fine. You can choose a actinic tube, too, but they are expensive. Any brand is useful, but i like Phillips 865 floro tubes especially: long life and very good spectrum (high peak at 440nm, good emision in all the blue range and a red emision about 15nm longer than others brand spectrums).

BTW, im in contact with some leds manufactures. One offer me manufacture a high power (1W) led running at 660nm and with a 30% optical efficiency. I compute they equal near 2w of a 600w HPS (and near 3w of lower watts HPS and CFLs).

But they ask me an advanced payment and a large order. Too much for just me, but id consider it if other people are interested in some. People interested, please PM me.

I must compute definitive cost (customs, freight charge, etc), but the price would be about 2,5-3â?¬/W.

Tell them, to build you a prototype.

If all goes well, you'll buy in bulk.

Advanced payment?
Nope. 1/3 payment when half is done.
1/3 payment when the unit is received.
1/3 payment when you're satisfied with the prototype.

Trust me man... I do wierd international business regulary... you're going to get fucked up the ass if you send them advanced payment.

As to a large order... hahaha!

Dude, they're trying to offload their surplus on you.
Also tell them to "fuck you". No large orders... prototype first.

What you going to do with shitloads of badly design bulbs? When they have your money?

Be smart man... be smart.

INTERESTIN!

Thanks a lot for your reply, Turtle420.

Im actually aware of this kind of suppliers. Im trying to comfirm its experience and reputation before any advanced payment.

I asked for samples before, and they agree. And a initial order of some hundreds, and they agree too.

They ask 30% in advance T/T, and rest before shipping. I agree with 30% in advance, but demand and escrow service for the 70% left. They agree. Im seeking for a preship inspection, too.

But im very concerned about a fraud. So any advise are welcome. What else can i do? (you can answer by PM, to keep clear the thread)

Thank you very much, Turtle

Hey dude... when you says "hundreds"... for surely you must mean "hundreds of LED bulbs..."... right?

Not "hundreds of LED bulb assemblies"?

If it's individual LEDs... that sounds... 'bout good.
Assembled...? Nah... can't be assembled.

Hey man, Kudos for getting them to accept the 70% escrow.

I don't want to bitch, but it's been my experience that money will make people do son-of-a-bitch things.

As to the escrow... you might want to try GetAFreelancer.com... they've got an escrow service... problem is, they'll get a X percent of the project cost... and you'll have to disclose what you're doing on the Freelancer.... and you don't want to tie your real name/address to cannabis stuff....

Nothing... I'm sure a google search would come up with various escrow services.

Keep us updated man... sounds good.
