Nobody is trying to deny anything. It was a prematurely made thread. The OP didn't give Richard a chance to replace his light before making a judgment that Cool Light sucks. I had a similar situation with Varizoom a while back when they sent me a bum ground spreader for a tripod. But I didn't make a thread telling everybody that the product sucks; I wait until I get a replacement (BTW, that product does suck, but it's another story).
Based on what Gabriel wrote I'm not sure if it was the light that failed. It's not obvious at first, but the CMD150 requires some cool down time when you turn it off. The first time I used it I unplugged the light to move it and when it wouldn't turn back on I thought the light was malfunctioning too. But I waited a few minutes and turn it back on and it works. Even the manual mentions this, "If you turned off the fresnel or should the power go out, you should not attempt to turn the light back on for 5 minutes. This is known as a 'cold start system'."
