Found out Kessil light don't use Cree or any of the other 3 major led companies, they use DiCon LED and a good thermal management that keeps the chip cool here's some of what I found and what they told me
Why so many LED grow lights mention “CREE”?
Here is a bit background. In the LED world, there are 4 top suppliers. Cree in US, Osram in Germany, Nachia in Japan, and Lumiled/Philips (used to be a US company till bought by Philips a few years ago). These 4 companies make the brightest LED chips and best package LED light cells. They represent quality. Behind these 4 companies, there are a lot of manufactures in China, Korea, and Taiwan. Some of them are chasing the standards and advancements set by these 4 companies.
When someone says, “ CREE LED used”, the implication is, “my product is very good, because I pick the best material out there in the market.” This is a trick many lighting fixture manufactures use to create the “perception” that their product is top quality.
Let me try to use an example to explain what I mean. For those of us who remember the 80’ Desktop PC revolution, there were so many desk top PC brands or shops out there during that era. Anyone can open a computer store or start a PC brand. “Big Mama PC”, “Uncle Joe Computer”, “Superman Technology”…. they all sell desk top PC. And what did many of them claim? Intel CPU used. (Intel 286, 386, 486, 586, Pentium I, II.III….) The patented phrase “Intel Inside” was a popular phrase.
Does having an Intel CPU make the computer great? Not necessarily. Now we know that besides a good CPU, you need to have enough memory chips (and clocking at the right speed), you need to have good graphics cards so your computer games looks good on the monitor, you need to have a fast network card so you can watch the video on the net, and you need a good motherboard to pull everything together, and you need ……. You get my point. When Desktop PC first became popular, many consumers were fooled by the “Intel Inside” label and not knowing the rest of the computer system needs be up to the scale for the PC to perform. Many vendors take advantage of the situation and make profits out of it. Forward 15 years. All those mom and pop brands are gone. With enough education, consumers know what to look for. In today’s market, people go for the few well established brands, like HP, Dell, Toshiba, Apple.
LED lighting market is going through the similar struggle. “CREE inside” does not guarantee the quality of the product. LED chips are like the CPU, but for a light fixture to perform well, there is more to just the LED. Is the thermal system being properly designed so the “CREE LED” will last as long as it should? Is the electronics for the LED driver the highest grade? If not, the board can burn out quickly. Is the power supply well built, if not, you are not going to get a good energy efficiency. Is the optics being reviewed, so the light is not trapped somewhere and get lost in the system. For the LED grow light we are interested, is the Spectrum of the correct one. Not all the red lights are the same. There is a lot to be considered… However, most consumers at this point do not have the knowledge to understand all that and many vendors are taking advantage of that by pasting the “CREE” or “OSRAM” or “Philips” or “Nachia” names all over and claiming outrageous growth results.
The Kessil H350 is called that because it's equaled to a 350w HID[/QUO
OK. Not bad. Did you write this up or is this straight from that comapany? This is where I have done my homework. First off, I dont know how much those lights are but they say it will do a 2x2 area. That is very small and I would believe it would be hard for it to really do that once the plant got large. So to do a large area you would need a bunch of those suckers!
Now, when they talk about these other brands of LED's you have to be careful of what they are telling you. I have researched this to dealth and have also contacted these manufactures directly. First off, do you know who supplies Cree with other of their products? Osram does! Osram is also world wide company. Just one of their plants is in Germany but their main one is right here in the US! Also Osram just bought out Sylvania or merged with them. One of those two. So my point is that I did see that that light was just introduced in April. So I am sure there is no sample grows yet. I have never heard of that LED company they say makes their LED's. Bottom line, it sounds to be a good product but the only draw back is that it would take lots of them to grow many plants.
Myself, I am not only looking for the best product out there but also one that has the most coverage! If you get some let me know how they do!!
