the SS L0D pic from Nightstalker make me thought of something
i wonder why do the flashlight menufacturer
dont make something that is useful for the non flashaolic
other then only flashlights
something like this USB led light or
an USB adapter to power our Powerful light
or even an adapter to power the flashlight head from the wall socket
dont you think that is more useful then just for flashlight use onli
we can use our light to lite up our home, notebook, or as night light but with out battery
they been making flashlight for years,
why they never come out with things like there?

hehe, i thought abt the same thing before. But i realise LED flashlights setup are alot different than household LED lightings.
It's good that they can come out with an adaptor and diffuser to make our flashlight head a house lamp. But conversion from AC to DC is not cheap, moreover need to consider the power factor so won't end up in low efficiency or LED burning. Heat sinking is a big issue if you would run for very long hours as a household lamp. People like us with experience would know how to leave the light on in general mode, but only good for ambience, not for reading. Household lightings are generally meant to switch on and switch off, no maintenance until replacement. You'll have users to treat a flashlight like a flourescent lamp, a very expensive "flourescent" lamp. It's either they design a flashlight only or household lightning only.
In LED professional website, manufacturers like Philips, design LED household lights but look at how large their heatsink. The light need to perform under serious circumstances.
Energizer has come out with household LED lighting as well, but it has a DC adaptor to recharge the batteries, which is a better cheaper solution. Their product is quite innovative, the head lamp can switch with different host and become a table lamp, flashlight, lantern, wall lamp. But don't know about quality.

We have a local LED household lightning research company in Malaysia called
Tim International. I saw their booth in One-U earlier this year. I sent him emails and kept in contact for a while and was willing to try out his household lightings. But so far no progress. I've also ask him about his flashlights which I saw on the booth, but he said they are not focussing on flashlights that time. Don't know what's the status of the company. Website still under construct.

I am using
http://www.dealextreme.com/details.dx/sku.4151 to charge 4.2V battery, and add a diode when charging the LifePO4 (hehe, will take picture later)
Interesting, would like to see a pic of the diode, you mean a resistor?
For some reason, I can't load DX anymore... looks like it just got blocked from here
