Cree just set a milestone by creating an LED light that puts out over 150 Lumens per watt http://www.electronicsweekly.com/Articles/2011/08/05/51614/cree-labs-demonstrate-record-breaking-led-light-bulb.htm Anyone interested in the highest output flashlights or headlights already know about Cree, but if you're new to LED technology, let me give you a few links you might want to check out check out the Coast X21 flashlight and the Coast P7 in this video to get an idea of what Cree LED's can do > http://www.youtube.com/watch?v=_ZG9KBtmRtI The X21 and the P7 both use Cree Q5 LED emitters but they have been out for a couple of years now I have a 2 year old Rayovac Headlight using a Luxeon K2 Emitter at 3 watts putting out 85 Lumens and a newer one that puts out 105 Lumens using only 1 WATT with a Cree emitter. Its pretty awesome for a bike light The following ad shows the newer (105 Lumen X 1 watt Cree LED) headlight in the photo but is actually an ad selling the older 85 Lumen X 3 watt Luxeon LED if you are interested > http://www.batteryjunction.com/rayovac-sports-ex.html If you do a lot of video shooting and need portable LED lighting running on batteries, Cree has an LED for you! I only use soft lighting for video and sand the front of the LED's with #400 grit wet/dry paper to get a really nice difuse light source Adding a difusion filter will cut down your light output too much To understand why a difuse light source is necessary, compare the hard light output of an old flashlight to one that you frosted or sanded the glass lens using wet/dry paper Even with a frosted LED and lower voltage rechargeable batteries, my 1 watt headlight ROCKS Coast flashlights also have a similar headlight but nearly double the light output and it has a focusable lens to go from narrow spot to wide flood Check them out sometime if you need a nice light Edited by A Storm is Coming, Aug 6 2011, 06:02 AM.

Check out the Cree XM-L's I gotta git some! http://www.youtube.com/watch?v=RMbTbqZNub4 http://www.youtube.com/watch?v=_rZ2FQ-7iLg&feature=related Someday Soon all my Video Lights will be portable, rechargeable, Dimmable, have a focusing beam from 30 - 60 degrees, have Soft Light Difusion Filters, be Daylight Neutral around 5000K or less, light enough to clamp onto just about anything as well as being tripod mountable I know this because it sounds like a fun winter project for me .....and I hate video lights that I need a truck to carry them around in
