I wouldn't expect them to tell you where they got their diodes either. I've seen some things throughout the net on how to make your own LED lights, I suppose anyone could make them if they could simply buy the {right} diodes/illuminators from the source directly. The price on LED's is still ridiculous. We all know that price drops in time on like everything but drugs and prostitution, but with the "Next Generation" LED's coming out every 3 to 6 months, it's like televisions today. How quickly can we make them better to jack the price & make the consumer start all over? Cali.....What generation are your new LED's? 3rd Gen? Certainly not cheap, although obviously cheaper to run especially considering you don't need as much coolers in your room, not to mention the wattage consumption. I just got a new 600 watt digi & it pains me to do it, because I really wanna go LED's, it's just that unknown..... "Will there be a bigger, better, cheaper model next week?"
