I've been using my Microstream for awhile now and it's become one of my most used lights. The unit that I have has what I consider to be perfect tint, beam pattern and general purpose output. I was wondering, however, if there was somebody out there who is able to make the MS a dual-level light. While the current output level is ideal for a huge range of uses it would be nice to have a lower level for battery life and for dark-adapted eyes. Something like 4-5 lumens would be beautiful. For that matter, seeing as how it uses a Seoul emitter you might be able to get a 30-40 lumen "high" mode instead of a low. I don't know the specs of the emitter nor do I know much about electronics in general so that is purely conjecture but that would be pretty sweet considering that great beam! Anyhoo, if anyone thinks that might be possible I'd love to hear from ya'........................
