Building your own SteriPEN

[Wangstang]

I don't know if anyone if familiar with the SteriPEN, but it essentially uses UV light to kill anything that can make you sick in contaminated water:

I've got a few Surefire 6P lights as well as a drop in UV bulb from SolarForce:

In theory, could I use the UV bulb in a 6P to create drinkable water?

It looks like SteriPEN uses some sort of an acrylic cone to channel the light down like a light saber into the water source to ensure full penetraton of the light.

Is there a way to construct a similar cone for the 6P?

Thanks

Norm,
I stumbled across that thread last night which I also posted in.

It looks like these LED's could be used:

The problem would be sourcing them, especially in a drop in configuration.

I suspsect that if one could get these LED's into a 6P drop in, you could sell a large supply of them to the Survival/Camping crowd. Given the voltage available from the 6P battery configuration, I would think that you could treat water by the 5 gallon container and not the smaller container sizes that the SteriPEN products are designed to treat.
