Huntlight FT01 Cree Buzzing?

IndecisiveFlashaholic · Apr 15, 2007

When I put my Huntlight in 4th, 3rd, 2nd, and 1st modes (5th being brightest) the flashlight makes a buzzing noise heard when held up to my ear. Does anyone else have this happening? Is this normal for an led to do this?

Not noticed on mine, although I did note that I can no longer go back to "high" with a longer press of the tailcap. It now has to be turned off a while to defaul back to high. Otherwise I have to cycle through all the other modes.

I don't notice it on mine either, but a lot of lights that use PWM for dimming make a buzzing sound.

Do you know why this is (lights using PWM buzz)?

I think it may be the inductor of the circuit humming with the pulses or something.
