Hi I'm new here and am trying to make a new Led lamp for diving where the lamp switches of when the strobes I'm using flashes.
any idea how to do this? and what led is the most usefull one for this?
the lamp itself doesn't need a lot of lumen but is just for the autofocus of the camera. using now a, home made, 7led diving torch with a wide angle light and the same color as the strobes but this is not always convenient specially in fast streaming water.
