will 400w of led challenge a 1000w hps???

i run 2 240watt LEDs (3 watt led bulbs) and i stack those both next to each other for a total of 480 watt. They don't quite keep up with a 150watt HPS so I hope this answers your question.

3-4" off the top of the canopy.

I am using those all now for seedlings and they are doing well at about 4" above the seedlings.

  • LED hatters come check my thread. I will post the plant cam stop motion at the end of the grow. I did drop some serious coin to get my unit $2000. But i save 300 watts of electricity cost thats about $12 a month in savings, not counting heat, plus no $129 bulb change every six months. And I usually can't run during the summer and am still running 2 LEDs plus one 1000 HPS despite record heat this year. So that is huge. Will a 300 watt led hang with a 1000 HPS, hell no. Will a 710 watt LED hang with a 1000, HELL YA! and I can keep my flower room running during the summer.

do you think 2 X 200w bridgelux 3w leds blue, red n orange spectrum would be better than a 400w hps? :-/

Hey,
No you really need a full spectrum of light to produce high yields. The auxilary pigments are necessary for rapid photosynthesis. So if you had 15 different LED wavelengths you would get there. 4 is going to come up short

Are the 240w actual draw because the blackstar 240 draws 135 actual watts. I know because I own one and have used a kilowatt to confirm.

People are jaded because of the silly marketing tricks led distributors and manufacturers use.

I get good results with leds. I only use led in my veg tent and I use hps with two led units in my flower tent. The mixed spectrum works wonders.

What you really want to ask is will 1000 watts of led outperform 1000w of hps. That's apples to apples.

i gave them a try with a 120w senua 2w bulbs, absolute shite, cost me £150 and i put 6 plants under ,ran it alongside a 400w , after the led got its arse kicked for a while i took it down and sold it for £120, so for me the best thing is they hold their value lol

would make a nice grow light maybe,or supplemental lighting but the hps beasted it in flower, and then the hps finished the job off on the ones i started with led's, just my personal experience...

i concluded that 2w leds are no good at all, but i may try 3's or 5's out again in the future, i do think that they will overtake hps one day but that is way off...

whats the penetration like with the latest models ?

This is how leds get a bad rap. A consumer buys 2 units thinking he has 480 watts above his canopy. Then he finds out its more like 270w from some dude on the interwebs.... Not good for consumer confidence.

Still leds have a place in the grow room, filling a specific niche. There are some countries that have rates at 40 cents per kwh !!!

I get good results and so do many others. It's a little different than hid lighting in that you feed and water less frequently.

I agree, I am obviously pro LED. But most the companies are selling snake oil. And it hurts the good companies. They make crazy claims like a 400 will hang with a 1000. and that it only cost $400. I wish. It really is you get what you pay for. HPS is cheap, it has been around since the 70's pretty much unchanged. You want to hang with a 1000, you need to get a good unit from a good company. And plan on paying for new technology. 3 years from now the price will hopefully come down and the bad companys will be gone and everyone will have a better understanding on LEDs. I dont expect my $300 dollar acer netbook to hang with a 2600 new mac, why would i with my lights be any different.

i have not heard any good about led. however, i have been looking at the inductive lighting. one company indagro, is a cool site. looks like they never were out. use much less energy, and are not hot. if i were gonna change, thats the way id go.

not even close. LEDs have shit for penetration. they are better off used as supplemental lighting, and work well for that. better than CFLs. if your looking for new lighting technology, plasma is where it's at!

Pizzapuffer,
what do you mean by penetration? i feel this is a word thrown around with no meaning. A photon of non uv will not penetrate a leaf. when lower canopy bud is larfy and does not devolpe fully it is because enough light did not reach it. Inverse square law of indoor lighting has nothing to do with penetration, rather totaly YPF. if someone bought a cheap shitty LED that only pulled 200 watts it will not produce very many photons. Has nothing to do with penetration has to do with total photons produced. a big led array that produces lots of light will "penetrate" just as well as any HPS. Shitty LEDs are shitty. Good LEDs are good. There are not many good LEDs and lots of companys sell snake oil. Take a look in the led section and you will some a few getten it done

i was thinking about trying my old 60" rear view projection tv if it still grafts, i bet them new LED tv's work a treat as well. lol
