"In regard to lights just listen to the first person who responded"
Don't agree with you and it seems that you presume too much. I was into LED's more than 6 years ago. I have been an advocate for them for a long time. However, until recently, I had not had the chance to grow under HPS. Now that I have, it's going to take a lot to move me from it.
IT's easy to make statements in hindsight. At one time CLW lights were among the best. No one can argue with their build quality. Out of all of their lights that I've used the Solar Extreme 500 gave me the best results. For under $400 show me a COB that provides equal or better value that offers 400 true watts, has a 3 year warranty, is American made and it's light spectrum is right in the sweet spot of the McCree Curve. So, yes, for a tent needing lower heat and excellent performance I have no problem recommending the Solar Extreme 500. I own three of them and have used them for several grows. Have/do you own any of them to make your claim? I did not say that I didn't like them. I said my results were not what I thought that they could be. Also, in stating that I thought the Solar Extreme gave me the best results I acknowledged that the newer LED cob technology was the most effective of the three that I've used from them. So Professor, maybe you need to check your reading comprehension....Okay?
