Yea i don't buy into these claims that a 100w is the same as a 400watt hid. I will not argue that some LEDS are boss, there are alot that are terrible. I think this is mostly marketing done by companies. "1000 watt HID replacement!" or "600 watt hps replacement!" I don't doubt some leds out there make the cut to out perform HID lighting systems, but i still don't see the power savings. a youtube grower did a side by side using a 600 watt hps bulb and a grow blu 240x3 (500 watt draw from wall) the yeild was close the HPS pulled about 1 oz more. Same strain, same nutes, both in DWC. There was a difference in the bud, the led seemed to have a bit more crystals.
Lighting are LED's efficient?

I have done both HID and Led... I like both, but pitch it to the old lady that I am growing green!!!! She is getting tired of that joke
But, I do like the Led aspects of things a bit better. I don't care what I pay for electric out of the wall. The old lady pays the utilities and I pay the rent.:thumbs:

from what I'm seeing with mine, I'd say you need 400 watts of LED to equal 600 watts of HID, so about 33% more light efficient. Then add in the reduced thermal load, and the 33-35% less power consumption, that's what makes them superior in the long run. But a 100 watt equal to a 400 watt? no way
pop22 your logic is sound, i can see that, its more of a realistic assessment then 100 wattage led equals 400 watts hid. This thread has made me see clearer with the leds currently on the market. I think i will spring for
Four of these http://growblu.com/apollo-180x3w-full-spectrum/ to replace two 600 watt leds. Thats not a power draw savings, its adding a bit more but hopefully with that configuration it will out perform two 600 watt hps. I might just run both side by side to do a comparison
[h=5]AVERAGE WATTAGE DRAW-360[/h]1440 LED power draw from the wall
The two 600 hps are about 1300 draw from the wall.
This would probably make a good comparison

Yeah I dont buy into 100w = 400w either. But I know that if you run the same wattage of hid next to the same wattage of LED you will produce more on the LED side. Thats enough proof of efficiency for me. It's interesting to note though that most commercial legal large scale grows are running HID. There's got to be a reason for that... it could be a case of sticking with tried and tested methods...
Also... im not sure if I'm shopping in the wrong places... but there's heaps of hid setups that cost more than my leds or the same... and then u gotta replace bulbs as well.

Not trying to sound snarky. But, you're going to buy a fairly expensive Cidly-type light, whose marketing claims were discounted by a youtube video? And, which doesn't disclose their spectrum?

My local hydro store doesn't feel LEDs are ready for primetime. I might agree with that. I'm a little skeptical of the extremely notched bands of light. I think it's significant that some makers are moving toward full (white) spectrum.
My hydro store, while cautioning against LEDs, has fallen in love with Phillips ColorMaster ceramic MH light. It's white. Supposed to have the highest PAR value. I wonder if these things are coming together.
I'm relatively new to all this. I have no idea if white light is effective. But, it seems like two things are coming together.
My local hydro store s****** (snig-ger) behind their hands and point at me every time i go in there...lol not really but they warned my right off LED's, i said i'd find out for myself... And I have. They're brilliant. I cant wait to show them a few snaps of buds grown under LED in all their purple tinged goodness.
The GroBlu are from what i read,etc, to be very good lights. Not cheap, but not horribly expensive either. I'd buy them if I had money for a high end light! HygroHybrid on youtube is doing a side by side grow. Two areas, both 4'x8'. One with two, 1000 watt HPS, one with two, 750 watt GroBlu's. He has a ways to ge yet, but its looking like those GroBlu's are kicking HPS ass!
The reason you don't see it much ( YET ) in commercial growing is multifold. One is upgrading from what you already have is a HUGE expense. Also, LED grow technology is only now, in the last couple of years, reaching the point where it is truly competitive. Then you need to find a source that can be trusted, that will be timely with warranty repairs, etc. If a company such as say, VIPAR could establish that they are reliable, that they have the resources to honor an orders for up to hundreds of lights quickly, then you'll see a rise in commercial use. New grow ops are starting to adopt them, as pricing is at the point where even pay triple for the light, will save big money on electric use, reduce air-conditioning needs tremendously, money saved on not stocking replacement bulbs, etc.
