LED lights is a subject i have taken a lot of interest in and is something i have personally researched.

I have placed the following lights companies in order of my personal prefence

1 http://www.hydrogrowled.com/ - Penetrato X Pro range of LED grow lights

2 http://www.357magled.com/ - Magnum & Magnum+ Grow lights

3 http://www.proledsys...lights/evo.html - EVO LED grow lights range

4 http://www.prosourceworldwide.com/ - Make the UFO range (these are the real deal UFO not cheap knock offs)

The Hydrogro "Penetrator X Pro" lights are very highly thought of and have been proven to produce good results. This what I am personally going to buy. Quality isn't cheap but they are the market leaders when it comes new inovation. A good number of grows on other forums, with good weights and smokes.The Penetrator X Pro range uses a secondary lens which refocuses the light and produces better depth penetration of the light.

Magnum 357 A good light with lots of proven results, there are many grows on many different forums producing a good quality smoke.

EVO fairly new to the scene but using high Wattage LED's This is what our Mr X uses and he has reported on ICMAG that he has achieved 2.4 grams per watt with them. That a high yeild per watt even when it comes to HID! Though there has been discusions about the LED driver (quite a technical discusion on ICMAG forums which were a bit beyond me), the LED's nearest to the power source are brighter than the ones at the furthest point away from the power source. Something i hope EVO will rectify in the future.EVO offer 60 and 90 degree convex lenses. Which i am guessing do the same job as the refocusing lenses in the "Penetrator X PRO".

Prosource 90W &180W UFO LED these are good LED lights and not the cheap imitations from china. A reputable company with a good product. These are the real deal UFO lights with good results on other forums.

As for your inqirery about Kessil LED lights it seems that they make single colour LED lights which would seem that they are to be used for supplemental lighting ie used inconjunction with HID's etc. Here is a review for you http://ledgrowlights.../kessil-review/

When buying a LED grow light it is important to note that the wattage shown is not alway the wattage drawn. The reason is if you power an LED at it's actuall Wattage rating the life is shortened and will fail earlier, so they are often powered at three quaters to a half the stated wattage so to have a long life and not fail. Some companies do state actual draw. I have provided links to show actual power drawn.There is a lot of reading that can be done, some of which i will try to compile when work allows (I'm very busy at the moment).

Try to check out as many LED grows here and other forums as you can, proof is in the pudding.

LED lights are generally better used by small grows at the moment but as tecnology improves and price drops i think larger set ups will start to use them.

Also check out grows by Toaor, MrX and Jay ryan in strainhunters forums
