Has anyone read something more about the news on the olight-homepage ( http://www.olightworld.com/news/cn/news_detail.asp?id=121)
about the new Seoul emitter?

"The single package product emits up to 420 lumens at 600mA maximum and 350 lumens on average. The size is ultra-slim, similar to that of single LED packages emitting 100 lumens. This high power package provides more freedom in design applications and lowers the price of the applications."

The efficiency isn't that great (only 50 lm/W). An R2-bin Cree running at 1 amp should be able to put out 250 or 260 lumens at greater than 70 lm/W. Seoul's 8 watt LED would have been more impressive if it put out at least 800 lumens.
