"White LEDs fabricated using these novel XBright chips produced 4.1 lumens of light in industry-standard LED packages with an electrical energy conversion efficiency of 65 lumens per watt (lm/W) at 20 mA."

65 lumens/watt. Drool.

That would mean a 5 watt version would kick out 325 lumens. If you could package 10 and harness the output efficiently, it would be rivalling HIDs.
Ill take 100 please [img]/ubbthreads/images/graemlins/grin.gif[/img]

Now let me see ... 12 of those will give nearly 50 lm. A 3W CFL put out 100 lm. Not bad! 12 for my 12 LED lantern please. [img]/ubbthreads/images/graemlins/grin.gif[/img]
