Re: hds runtimes.

I keep both my EDC lights at level 20 (.08) for the min. setting. It's great for around the house with dark adapted eyes. Wonder how long that level lasts? Anyone care to guess?

Re: hds runtimes.

Hey TG you've inspired me I have an early serial U60 I'm committing to not using for the next month or so to figure how long low will last.

I've set it to level 20 and I've just started the test.

Since this is a test of run time and not brightness It shouldn't matter but I'll mention this HDS has a Edison opto emitter which is about 2x as bright as the stock Lux so it be about 0.16lms.

Re: hds runtimes.

Very interesting - the new Twisty is listed as running for "only" one week at the same light output you are testing at. Yet, it's hard to imagine the new light being less efficient (have to wait till they ship in January to find out)

Henry is like Surefire when he rates things. It's the worst case scenario. He probably took the crappiest LED he had and the worst driver he had to get that rating.

Re: hds runtimes.

And then rounded it down. Henry is a true pessimist.

And that is a huge part of why it's easy to be optimistic about his creations :thumbsup:

I've got a rugged twisty on pre-order and will attempt a similar test when it arrives. The challenge will be finding a way to compare or measure the light output to determine when it steps down as the battery nears the end of it's life.

Re: hds runtimes.

Well done.

Just to clarify (maybe I missed it, but I did look) - what battery were you using?
