LED vs. HPS

[THContent]

How do you guys feel about this:

600W LED Grow Lights (Quad-Band) - China Led Grow Light,Led Grow Lamp,Led Plant Grow Light in LED Light

or this:

600W LED Grow Light /LED Grow Lamp/Grow Light (SP-ZB600) - China Led Grow Lights,Led Grow Lamp,Grow Lights in LED Light

or last but not least:

China 600W LED Grow Lamp. Shenzhen Manufacturer

Which one should I go for?

I found this one, it rocks 3W diodes min order 5, which I will use.

Super 100% 3w chip full spectrum 600w led grow light with extreme flowering and fruiting products, buy Super 100% 3w chip full spectrum 600w led grow light with extreme flowering and fruiting products from alibaba.com

That's a nice looking panel. What's the cost?

I'm thinking you are going to want some diodes in the 680nm wavelength.

In the first set of links you posted, THContent, they're all poorly-balanced panels, and one uses rather wasteful orange diodes.

In the second link - it says it's using 3w diodes, but then it says 576 pcs of diodes and 600watts - AKA you're being lied to in the sale or they're under-driving the diodes, which DRASTICALLY reduces efficiency. It is also using wasteful orange diodes.

So I wanna stick to Red and Blue strictly? Red being 660nm, and the Blue being 460nm?

I know I want the 3W diodes, not the 1W.

Damn chinese, they can't speak english right, let alone get the specs. Should have outsource to the japs.

While dual-band works well, what I worry about is the fact that the one you intend to purchase shows 630nm for the primary red - not really good for good flowering like 660nm.

Also, that 100w panel is more expensive than my own 120w. I'd almost daresay you'd get better results with mine versus that. That one might provide better penetration power, but I think I'd win on overall yield.

Seriously, get Stra8 to get you some of what he uses before you go looking for the online specials. He's already got a great working formula down.

Packaging Detail: Packing is very pretty

Interesting thread, since I have too many plants I'm moving two into a closet and I'm going to finish them under two 90W UFO's and four banks of dual 40W flourescent shop lights. For now I'm moving them into the garage at 6 p/m each night until I know they are both female then probably going into the closet to finish.

you can look at my album or my thread in my sig..i got some nice LED's :smokin:

OMG! Those don't look like airy loose buds to me. Impressive. How much $$$ do you have invested in the LED's. The heat from all these HID's is killing me!
