thanks fo the heads-up, ikendu!
i am very impressed with UK lights as well.
the combo of formafactor, reasonable price, plastic (yup, i actually like plastic!), durability and flexibility make them a winner in my book. the eLED 4aa is quite amazing for $20.
also, i was recently searching through some old threads, and it appears that the lamp assemblies on the 2 watt last quite some time, so perhaps the 4watt will be similar.
