LED grow lights... input please.

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.

I refer to some hundreds of leds alone (mounted in a star, like luxeons). For me, this is my best goal achieved in the negociation. But, at same time, it did all my fraud alarms sound. All manufactures i contacted previously demand at least 10000MOQ. This one, only demands higher price for lower cuantity, but not a minimun order.

I think its rare, start a line production dont worth for so small cuantity. They say the arent producing the product currently, but made it with an 30% advanced payment, but at same time they said they can send me the samples in 10 days. All this seems very suspicious to me. But if i receive the samples and they are ok, the order still be of a cuantity (600-700USD) that may hurt, but dont do me a poor man. In the other hand, when i request escrow payment, they dont say not, but ignore the question, without any question. Knowing chinese suppliers, im afraid when time to contract, they will put objections.

My other concern is they will not be capable of doing the leds as they say that can do it. I must test the samples carefully, but i only have the equipment for electrical parameter testing, not for optical testing. Hire a spectroradiometer must be expensive, but if the leds have the perfomance they say, it worth the cost.

First, im asking for deep technical details. If it satisfies me, probably ill asume the risk. But im going to do all step by step, i havent any hurry at all. I think it may be a good deal, but i dont believe it until i have the leds working as offered.

Ill keep you informed.
