  So basically the changes to electrical regs are a horrible thing and an annoying waste of time, but you're happy to write off what you have done and say who cares, I'll be dead? Hmmm, something doesn't seem quite right here......

  Oh dear, looks like you bought some cheap rubbish. Actually, good colour rendering LED's have come on market in the last couple of years, or if you like there's just plain old yellow tinted ones. I've got several LED torches, and the only one which has a bluish tinge is the rather powerful one that is now 3 years old and frankly it isn't that noticeable. If you look online there are plenty of non-blue LED's available. As for CFL's inducing seizure, I have searched google scholar and the internet, and all I can find is that there's no evidence...

  guthrie @ 151 & 152 Err... I think you are misinterpreting me, perhaps? Agree re: "colour temperature" of LED "bulbs" - can be almost any balance you want, these days. New or newish CFL's, once on, properly, don't flicker (much) ... but ... When they start to fail, like a standard flouresecent tube, they will flicker & if that frequency is at or close to a multiple of 7.3 Hz, you can be in deep trouble ... say 29.2 Hz (?) And it doesn't have to be outright seizures, it can be "simple" dizziness &/or nausea - I have seen...

  Alsa @guthrie #152 It so happens that I'm one of the people who can experience nausea from a strobing flourescent (usually one that's starting to fail). I've never experienced this from a CFL, but that doesn't mean that it can't/couldn't happen, just that I've never experienced it, and work uses CFLs on cutoff timers in toilets so we get regular failures....

  Okay that makes more sense. I don't recall reading anything you typed about the problem occuring when they actually fail. Obviously when something isn't working properly, what i wrote doesn't count....
