I was puzzled
at a 2 bulb bathroom (typical kind), one was slightly
dimmer than other and flickering like mad. (my eye can see 30hz
driving me nuts) So I tool bulb out to check. aha the stick on
diode disc. Yanked it. SOLVED.
Um, you have the frequencies halved. Normal incandescent light flicker
is 120Hz; with a diode, 60Hz. (100 and 50 for 50Hz power, of course.) /~\ The ASCII der Mouse
Thanks! What's the reason the frequency is measured as 60hz while
the "flicker" or blink rate is doubled that? The measured 60hz is
one cycle while the flicker include the two peaks in one cycle?
