I am wondering how these react when dimmed through PWM.
I am guessing that along with the light output getting dimmer the rate of cycle will also slow.
That is a guess.
Has anyone used these in a PWM application?
Is my guess correct?
Does anything else get screwey?
I am intending to use 16 of these to be driven by a TI TLC5940 chip controlled by an arduino.
This is only one piece of this complex lighting project, but I am wondering if this will work or not.

Would I be able to mount a bunch of these using thermal tape on an old transistor heatsink I have? The heatsink is about 1 inch by about 4 inches, was originally designed for 3 high power transistors. I would like to be able to use that then mount it with power supply in an enclosure as a small up lighting wall wash fixture. If possible I would like to drive it with 5V if I can find an appropriate constant current driver for it, if not I can go with 12v if I have to.
No public wish lists :(
