Wow! The chips look like a caméléon or a very nice rainbow, and 500W...cool and 120lm/W look good, but how much does it cost? And is it efficient as it look cool!??
Have a great day★

Just curious why anyone hasn't tried them. I just might give them a go after talking with them first. Hell they might give me a chip or 2 too test if not at a deal.

Just kidding ... Apparently LEDs Magazine did an article on these chips a few years back .
Alta LED exceeds 100 lumens per watt
Date Announced: 04 Mar 2011
Alta LED has been notified by a senior engineer of one of our customers that our 100 watt LED Chip has exceeded 10,000 lumens in their tests. The Alta LED 100 watt LED Chip will be utilized in site lighting fixtures as a replacement for high wattage metal halide and induction lamping. The combination of brightness and low operating temperature is what makes this LED Chip a superior product. Alta LED is located in the United States and the 100 watt LED Chip is packaged domestically as well.

redbirdled.com has some interesting strip lights also. Over 140l/w. 4 ft. strips at 44 watts each, for around $80. Also a US company.

Effeciency doesn't look that great. 80 LPW at test current.
Besides, I'd rather space that light out a bit. 50-80 watts per COB is plenty. The most I run them at is 50.
not enough density for a grow room. 4 foot strip needs 100 - 200 to be practical. fits well as a T8 or t5 fluoro replacement upgrade.
what do you think of their 50 watt cobs ?

The versions use the same tech so I think it would be 80 LPW across the board.

5 of them is the same cost as an Optic led, but 220 watts and dimmable.
