My kitchen fluorescent lamp which is 6 foot 100 watt unit wouldn't light tonite the starter flickered but no sign of any tube activity. It was very cold in the kitchen so I put the boiler on which warmed things up nicely I tried the tube again and although a bit sluggish it lit ( maybe my swearing at it helped) my question is do you think it's just because the tubes old and doesn't like the cold or is there something else going on?
Rather than waste power on lossy resistors a lot of the cell saver designs of torches do the dimming from anything other than full brightness by chopping the current waveform, so half brightness is the same as full brightness for half the time.
Which is an excellent example of how to spend a ha'penny.
Mike, you really are a mine of information. ?
So I just popped into my workshop and ran my lathe. Full power, no flicker at all. "Half power" definitely strobing. Doubtless if I gave you a list of the apparently stationery speeds, you would be able to tell me the frequency of my head torch.
