C3 Centurion 5W White Luxeon HOLA

Here's nice super bright 5W Luxeon SE mod:



And some more pics showing a little more detail:



This was made by stripping the bulb from the reflector, turning down the reflector a little, and then making the base/heatsink assembly in which the Luxeon is mounted. The reflector slides snugly into the heatsink assembly completely surounding the 5W Luxeon inside a nice completed heatsink assembly.

Now, I have to wait for the thermal epoxy mounting the Luxeon to set up before making any measurements. But quickie test show this to be the brightest 5W white Luxeon mod yet. The dimpled reflector makes for a perfectly smooth beam also.

Excellent! Making good use of that new lathe, I see...

Lambda,

SE or HD?

Way to go Kevin!

Nice one.

Would you say that the side emitters are the way to go from now on for bodies that have a reflector? It seems you guys are getting excellent results with them.

Ouch, look at the large hotspot on the ceiling!

And a quickie beam shot of the assembled flashlight.



Back to the closet to cure the epoxy more .......

Well done!!
A really super mod.
I expect that SF is working on their own version of a 5W in a 3 cell unit themselves.
I hope that you will post a runtime and case temperature when they are available.---Marc

Nice Lambda!

Now I have a reason to get a C3!!!!

I'm set, how about your light...

ok for the 30 ca-billionth time since i have been here, may i get in line please?

Lambda, will it be possible to make it regulated?

Alan,

I'd take a wild guess and say that there's already a Lambda driver inside there somewhere?

P.S. Who here has heard of "Full Metal Panic"?

While there certainly is room for a regulator in there, it's only purpose would be to buck, or limit current to extend battery life. And we really don't want that, do we?

This is just direct drive; copper regulation. Current seems to hover around 990ma with new cells, and so far heat doesn't seem to be a problem.

Anybody got any burned out P90 lamps ?
