... I grow outside... I am going to step up to LED...
Please, just refrain from giving people advice on what to do until you have some experience with LED. I don't doubt that you're an intelligent person, but you just don't know what you're talking about. Things are always being improved, and manufacturing costs reduced, but as FranJan said, it's today and many LED panels aren't capable of growing proper buds, especially the monochromatic LED panels. The panels that do have that capability just aren't that cheap.

So I bought some 300w LED's off eBay. Here's the link below.

300W IR Full Spectrum LED Grow Light Panel For Medical Indoor Flower Plants Grow (eBay - in case link below does not work)
http://www.ebay.com/itm/300W-IR-Full-Spectrum-LED-Grow-Light-Panel-For-Medical-Indoor-Flower-Plants-Grow-/271564432614?pt=US_Hydroponics&hash=item3f3a8064e6

So I understand that there has been discussion on many posts concerning quality LED's from China and these LED's appear to be good quality (plants have been growing well under them), but what I am looking for here from the community is if the wattage advertised is correct. I connected these 300w LED's to a killawatt meter and up displayed 98-99w.

So am I missing something?

I wrote the company::

Hello,
I have bought these 300W LED's. However, I recently had the chance to connect each one to a wattage meter that shows a draw around. 100W. Why is it showing 100 watts and not 300 watts.

Their response:

Hi, I am so sorry to make you confused.
The main chips of led grow lamps emit the red light. The red light accounts for 75% as per the reasonable color ratio. Meanwhile, the wattage of the led chips of red light is 2.2-2.4V. The better the chip is, the lower its wattage is. The Cree chips, as the best led chips in the world, have the lowest wattage with 2.0 -2.1v for red light and the lowest power consumption.
The high quality chips emit enough lights though with low power consumption.
Some shoddy led grow lights suppliers take the following measures to increase the power consumption:
1.Because the white light and blue light have higher wattage of 3.6v and use cheap chips, they adopt a lot of white light and blue light which are no good for the flowering and fruiting stages of plants to increase the power consumption.
2.They adopt inferior led chips which have high wattage and power consumption but little light.
3. They add resistance on the lights which will result in high power consumption and more heat generating but little light.
Our led grow lights have the reasonable color ratio with a over 75% percent of red light and include the real IR with the lowest wattage of 1.8V. Moreover, We adopt low wattage chips from Epileds.
That is why our lights have low power consumption. But the light our lamps emitting is adequate,actual and effective.
So the buyers have to learn more about the secret of led grow lights to free from deceives !If you are not satisfy with the lights, we will refund you unconditionally. Our wish is to Offer our customers a great shopping experience
Best regards!

Can some of you knowledgeable growers please educate me and provide your thoughts on the LED's in the link above and the company's response.

Look, I didn't tell him what he should or shouldn't use, all I said was that if he was happy with the way his plants were growing under the lights, that's all that would matter to me. I never said anything about knowing which lights would perform better under what circumstances because I don't have that experience, and I never claimed to, but as someone who knows quite a bit about the actual technology of LEDs, not just their application to cannabis growing, on top of a well researched understanding of industry and production in a global economy, I feel completely qualified to offer my educated guesses as to the future costs of the technology, so please spare me the "If you haven't grown with them you can't possibly have any useful info about them at all" garbage.

But it's now and if you want to play you gotta pay and that's been true of all tech really. And how long did it take computer prices to come down? All LEDs aren't created equal and are made in different economies that dictate wildly different prices. And please don't make assumptions like I'm thinking LED prices are going to stay the same. Believe it or not I'm not that ignorant there fella. Bro if you want to argue like a lawyer and "win" go right ahead. I'm trying to be correct. And sorry if that offends you, I respect your opinion and all but hate arguing in this format.
If you want to go by price to power ratio, computers dropped in price at a remarkably steep rate, and continue to do so. In January of 1985 512KB of memory cost $440, by June of the same year it had dropped to $275. In Jan 1980, the cost of memory was $6,480/MB, by Jan 1985 it was $880/MB, by Jan 1990 it was $106/MB, as of September this year it is $0.0085/MB. This kind of price drop is common in cutting edge technologies, there is no reason to believe LED will be any different.

Great breakdown.

Stay away from the Mars Hydro panels, they're bad news. Notice that nobody around here uses them. If you're going to go the inexpensive, eBay route, go with Vipar LED.
Thanks for the heads up Vipar was the first brand I came across but someone told me to stay clear because their claims of full spectrum are false and they include ir and uv in addition to using a ratio of 9:1 or 8:1. I was just looking for a inexpensive light with 180-300 watts for 100 bucks or less, LOL I know. Are Blackstar lights any good for veg and flower, (same questions with the Vipar)?

Thank you rob333 for the info, so I could (being a newbie) buy one of theses lights for my small needs and get like 2 or three ounces of a plant with the proper nutes for maybe two years or so before it needs replacement or replacement parts

Why waste your money on garbage when there is such better products out there for nearly the same price. This rob guy is just not thinking too clearly if he wants to buy LEDs like they are just throw away lights to be replaced like HPS bulbs once a year, buy a quality light and it will last for years. I would suggest an area 51 led, here's their website www.a51led.com
