I would only buy highest quality lights, to me anything else is a waste, as led is suppose to be efficient. it won't be if using shit chips/ old chips. led is expensive, or semi expensive.. I find building a crap light would yield the same as a cheap ebay light.. if your going to build, my idea is do it right ( high quality ) , there's no point in building when you can buy a light.. building is for if you want something special / more powerful / more efficient / cutting edge...
you want to put it in a PC case?
Google cree cxa3050 100w custom led grow....
He's using 2 cree ww cob leds. Couldn't be simpler and the results are impressive.
why i cant find 3590 or 3070 on ebay or anywhere else ?
I would stay away from the 3590 for now. You will be paying up the ass for reliable drivers. It runs something like 77v@1.8a. That high of voltage will require moolah and I don't think they are as efficient as the 3070's either.
Don't worry about that.woogille said:thats weird, in newark they say [about the 3070] that its 7390lm, while in cree's website it says its 11000 or so. also they didnt wrote how many watts .
I wouldn't worry about that either.woogille said:what do you mean - the 3590 are not as efficient as the 3070 ?
Money.woogille said:what is moolah ?
Poor choice of words. Nothing's going anywhere. He means that an LED driver that can supply 77 Volts at 1.8 Amps will be unnecessarily expensive.woogille said:im sorry for my lack of knowledge in electricity, but so
what will happen in the future that will make the 3590 'better' [or whatever] ?
and when will that happen ?
Do you even need that many Watts? I thought we were talking about a PC grow box? That's like a square foot maximum. I see many people growing fine herb with ~40-60 Watts per square foot. Anything over 100W is like, "Really...?"
Going over 100W/sqf with LEDS will require shading nets, like the one used on the greenhouses
But the driver will be expensive. That's what we're saying.hey man
for that kind of money for that chip i'd even go 200W
why ?
cuz its cheaper than if i'd go for 90 watts with other chips, and i guess that it wouldn't hurt if i'd had more powerfull lights
It is. It's been done before.besides - i could test these results with other pc growers that go - 'traditional' and use like you said - 40-60w and see if it could yield more.
isn't that logical ?
Yeah, he's talking about stunting the growth of your plants with too much light, and (comically) hinting at using a screen to block some of the light out.what do you mean ?
do you thing that light can be 'too strong' in such a way it could actually hurt the plant ?
what kind of shading are you talking about ?
