I'm laughing so hard at myself right now. I've had an AA Spectrum for YEARS....it's MULTI-MODE!?SO. The spectrum AA is both a pleasant surprise for the warm white and a major disappointment in terms of UI. The warm white choice of LED was great (looks like some kind of luxeon), but on both high AND low modes, it is exhibiting some form of pulse modulation on NiMH. Possibly PDM on high and HORRIBLE PWM on low (think cheapo chinese lights, maybe 60-120HZ TOPS). I could see it with my bare eyes when firing it up, even before waving the light around to verify.
The illuminated surface is fine, but don't even peek at the head while in usage or you will notice it. I'm debating tearing it down to swap out the nasty Pulse Modulation driver...
It has 4 modes, no memory, in this order: PDM High, PWM low, beacon, SOS. It DOES have a nice soft-start, mimicking the incan boot up quite well. The PWM kills it for me though...on fresh alkalines or freshly charged NiMH, no issue with high.
I've only ever used it as a single mode light. That's hilarious.
FWIW, I don't notice PWM on low for the one I was just looking at, and I'm generally fairly sensitive to PWN or any kind of refresh rates.
