LED grow lights... input please.

[SAtown]

Tried and true the 90 watt UFO is the latest and greatest in grow lighting.

The UFO replaces your 400-600 watt MH/HPS systems utilizing truly space age technology. Emitting virtually no heat, consuming a minimal 90 watts, very little light decay, no need for a ballast or reflector; Its no wonder NASA uses LED Technology to grow plants in outer-space .

The LED UFO Grow Light uses only 90 watts of power, rendering it 80% more efficient over modern Metal Halide and High-Pressure Sodium (HPS) lighting. Providing only the exact spectrum used by plants for growth means you use less power and get more of the light your plants love. Since the UFO uses state of the art LED technology the heat output is minimal at best, keeping your climate steady and your thermal signature hidden.

The UFO is suitable for all stages and applications of Indoor/Greenhouse Plant Growing. From Hydroponic and Commercial Greenhouses to your Average Hobbyist, the UFO produces thick, dense, healthy plants from sprout to flower to harvest!

The UFO can light up to 4m x 4m or 12' x 12' as the primary light source, or much greater heights as a supplemental light source.

(of course they don't give the exact type of led used, but I'm sure we can figure it out w/ a little research.

SAtown Reviewed by SAtown on 05-20-2009. 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.

As a user and experimenter, and a LED lover, I say BULLSHIT!

Claims like that are so far removed from reality there is no way I would believe anything else you have to say.

This is exactly why so many people don't believe in LEDs, they buy something based on shit like this and when it doesn't live up to those exagerated claims, LED's get bad mouthed. When in reality it's not the LEDs fault, the problem is some schuster trying to make a buck off uneducated people.

SAtown,
Many of us have tried and successfully used LEDs for growing, but I'm afraid that the info listed on that eBay store is just plain BS. Right now I'm using about 400 watts of LED and getting great buds.

14 watts is just plain not enough to grow and flower with.

Again, this type of LED info is what gives credence to the LED's won't grow cannabis ideas. LEDs will work but the efficency and cost of the LED needed is being greatly exagerated by those only interested in ripping other unsuspecting individuals off.

Sorry, bud...

He's not sayin' it, brah. He's just regurgitatin' what he read at the led bandit's on-line store.

Aloha, OldMac

Looks like dem ledwholesale shysters just made $32 off of that guy.
He's determined to try a grow with that 225 China panel POC and will find out that "Leds don't work"

So, you wanna tell him? Or should I?

Ah fuggedaboudit!
This little rip-off just might get him to do the requred "homework", yah?

Onward, to the great egress! -P.T Barnum

Just in case u get confused easily...http://imgs.inkfrog.com/pix/1Som_Bid...d_Blue_001.jpg

Tsk!
No need to get snarky with OldMac.
He knows what he's on about.


You sir, have made an error.


How do I know?
Easy, I made the same error when I was starting with LEDS.
Happens to the best of us.

Here's what's inside that China Panel.

As for the discrete leds used..
Gimme a J, gimme a U, gimme an N...


It's a fire hazard as well.

So, I took my lumps, threw it out, and moved on.
It served a purpose.
It made me read enough to do it right.
That was well worth the purchase price to me.

Not interested in an argument.
Just tryin' to save you some grief.

Hey Weezard, hope I didn't rub you the wrong way, somehow.

How's the lamp work'n out for ya?

I had to remove one of the Procyons to balance the heat load so I'm down to 435 watts right now. Gonna have to work on getting more air flow next grow. Still way cooler than my HPS rig. Had to install a carbon scrubber to remove the smell. My next door neighbor passed away last December and I have a new neighbor who might not be as friendly to my garden.

hope your present flowering is coming along nicely..

Hey Weez,

I doubt this ahole bought anything, he's been humpin' LED Wholesalers (Ebay ripoff artists) many, many times.

Everyone here should beware! This is not a source of anything decent.

Hey Weezard, hope I didn't rub you the wrong way, somehow.

If you "rubbed" me atall it must have been very gentle.
I'm quite ticklish in spite of my scaly appearance.

How's the lamp work'n out for ya?

So far, so great!
Oh, BTW, it is possible to veg. with only 15 Watts.
Just not with 15 Watts of crap.
I did build an working array of 300. 10mm. 70 Candela ea.
leds last year. Just to see if it could be done.
But, I used 660nm. reds 455 nm. blues and they are lensed to concentrate the light to a 15-20 degree angle.
I actually still use it for cloning.
And I had some success with HGL's 14Watt kit. for veg.

Sneak over the fence tonight and plant a few seeds in his yard.
That'll tell you if he's a "friendly".

I did that in Ca.
When the new neighbor came out and saw the new seedling he said,
"What ho!
A volunteer!"

We became good friends:joint1:

The last flip sprouted pubic hair in 5 days and is flowering nicely.
About even with my girls in da sun!!!
Better that I had hoped, actually.

But, I'm not jumpin' on da woohoo wagon, just yet.
I have seen underlit plants thrive for a month jus' fine.
Then the lower limbs start dying when the buds swell.
And I'm not talkin' yer normal yellowing fan leaf.
They shrivel like an unwatered seedling.
Whole branches just up and die.

That's why I upped the power and switched to 660nm.
V-shell-c in about 8 more weeks.

Then, if bragging is in order...

I'm watching your progress with great interest.

Weeze

Hey Weez,

Second and third that. O. M.!

I like to think that they are more ignorant than predatory.
Keeps the steam in., yah?:jointsmile:

"Sneak over the fence tonight and plant a few seeds in his yard.

That's a wonderful idea and I'm gonna see if I can work on a variant of it if I can come up with one. Mrs P and I sold our house and bought a condo when our kids grew up and married bout 20 years ago. What a dumb move in retrospect in so many, many ways...

But I do what I can with what I have. When I retire, all bets are off. We will be moving, hopefully with lots of land around us.

take care, Weezard,
