    Hi all,
    just wanting some thoughts on this topic. i'm getting some very random blinks from a couple of downstairs lights. i changed most of my bulbs to LED, and from browsing it seems they're a lot more susceptible to current fluctuations etc, there has been one incident when a normal filament dimmed for a second or two but aside from one genuine power cut to the area the only issue is the blinks. it's totally random, no pattern - can be days between them; the light will blink once usually, and that's it. i've read that neighbouring properties' usage can cause fluctuations etc and i'm thinking it might just be the incoming supply, what w/ the colder/darker nights prompting more lights/heaters etc. i've had the tv and other things on when a blink has happened, they don't seem to be affected. also, the blinks don't happen when i do stuff, switch the kettle on or of etc.

    is it something i'm just going to have to live w/?
    TIA

    Hi,

    LED bulbs don't normally blink, or flicker.
    They usually have drive electronics built-in, that will smooth some variations from the incoming mains.

    Although LED's can last for years, often the drive electronics prematurely fail; succumbing to heat damage.

    It could be that your bulbs are getting old?

    Alternatively, there may be issues with the connections in your switches or light fittings, and some LED's are incompatible with dimmers etc.

    Personally, I would try some different lamps, from a different brand, and see if you have the same issues.

    Good luck :)

    They have to have integral drivers, you cannot put 230 Volt onto an LED element ( well you could but the result would be mildly explosive )

    Some drivers do have adequate smoothing to cope with transient voltage events without there being a visual affect on the brightness of the LED element(s).
