Make a Head Light Flash Light Using Cree LED Chips to Get HIGH LUMENS with Less Watts

I was wondering if I can Make a Headlight Flashlight using a CREE LED Named XLamp CXA1304 g or any other LED from Cree .. I heard it can Produce High Lumen with less Watts Required. as CREE says they have reached 300 Lumens Per Watts...As, I want to make A headlight Flash light with High Output of Lumens to look into the Dark at A distance far away.

Any ideas, Is it Possible.

Its not clear to me what you are talking about.

Lumens are not what makes a light able to shine far into the dark...its a factor, but the focus of the beam is the most important aspect of that. Also, what is a headlight flashlight? Do you mean an automotive headlamp, at the end of a battery tube, or, a light strapped to your head, or what?

So far, it just sounds like you want to make a light of some kind using a CREE LED....which is certainly doable.

You may want to look at some existing commercial headlights & see what LED is used, how it's constructed, etc. The Nitecore HC90 is one example, 900 lumens from a CREE XM-L2. The Fenix HP30 is also 900 (burst) lumens & uses the same CREE XM-L2. Same with the ZebraLight H600W MkII, etc.

Also quite a few have been built by CPF members like this one: http://www.candlepowerforums.com/vb/showthread.php?257955-Build-Log-Double-Triple-XP-G-R5

Yes, a light strapped to head.. I was thinking of adding a battery to the led, u know the dc battery has to be small in order to fit on the head ..so they usually are of low voltages, so their of i am looking for a LED which can produce high lumens and require less watts as input.. After reaearching i found out this CREE Led which I meantioned on the top..
And what you say about lumens.. High lumens are bound to produce more long lights..

Tell me all ur views

So none has a solid solution to this matter..!
