UV is a good way to treat water and as light as any filter. The largest weight penalty is the spare batteries needed on longer trips, since they only last about two or three weeks. With a LED producing UV-C, longevity can be greatly increased. I would guess a minimum of 3 times. The LED produces the same band of disinfecting UV light and at a 12% efficiency! Yup, you read that TWELVE PERCENT! And, they are typical doped electronics. Not the power guzzling mercury bulbs currently available with the largish starting draws.Mar 3, 2017 at 5:02 pm #3454226

The Cornell Spin Dept is boasting. UV LEDs have been on the market for some years now. To be sure, the early ones were very weak, but recent developments have been much better.
They are quite feasible: all that remains is to increase the efficiency and decrease the price. That is inevtiable.
Nonetheless – yes, they are coming.
(Yes, I am monitoring these developments with great interest, and so are others.)
