Mr Red BS: Rough service light bulbs (44) RE: BS: Rough service light bulbs 13 Mar 18


We changed evety bulb in the house to LEDs as soon as we could

Well all I can say to that is: "don't read in bed" - the fluorescent gels (yes they are fluorescent lights FWIW) act the same as fluorescent tubes & CF in that the phosphors are excited by blue or ultra-violet light, and fluoresce at R, G & B much as yer; phone, TV, Tab & PC screens do.
The heavy preponderance of blue fools the eye/brain into thinking it is nearer to mid-day than it really is. ie you should be awake. Insomnia sufferers beware, they all will only make it worse.
And there is concern growing about how street lights are being changed over to LED and that changes insects' hunting strategies and alters predation, and the balance of insects. (think blue) Consider the concern over bee populations (not necessarily honey types) doing pollination for free. Or not! Basically we will know the effects when it is too late. Nothing comes for free!

My bedroom switch is a dimmer/remote and that has to be tungsten. Plus I read the New Scientist to put me to sleep
and it does. But the kitchen has an LED strip light. I advise not going for the PIR models, they detect only within their length! And the saving in power is nill!
