TIP, LAD, and Tube, spinning around on a ball chain.
It seems like you really want some evidence of PWM Jon, I've been unable to find it. Maybe they bumped the frequency way up with V2?
They were all spinning fast, the Tube shot really shows off the effect!
I'd bet that an incan would hardly be noticeable with PWM as the element wouldn't cool off quick enough between pulses. LED looks to be
OFF as soon as the pulse switches to zero.
I took some 60FPS video and thought I had something for a moment but it was from my monitor, went away when I turned it off.
That's all I can contribute to the PWM debate because the reactions going on in here make me feel like I'm missing something.... I guess I've been away too long.
If you can live with the little nitpicky things, any of these lights beats out the old CR2016 lights simply because they're rechargeable. And despite the visible flicker of the Tube, it's the one I put back on my neck after the test!
I'll shoehorn the other ones into my life, finding little places where I often need lights is easy in a 100 yr old house and when you work at a place that so broke we can't replace light bulbs.
