[QUOTE="Vipersan, post: 963129, member: 325666"] Interesting ... Got to be a function of the led transformers switch mode frequency ... interacting with the rotational speed of the drill.. obviously this not normally being visble it being well above the response time of the human eye/brain. Only made visible 'cos the 2 frequencies come close together. Such discrepencies would be ironed out by the thermal lag of a filament bulb warming an cooling at high frequency...but as we know an LED can respond much much quicker .. Fibre optic coms relying on this fact.. A bigger smoothing or resevoir cap on the DC line to the LEDs might damp the strobing ..if it were a real problem...but not being problematic in normal use ...they wouldn't put bigger caps in than needed..is my guess. rgds [/QUOTE]
