LEDs - Are Most Now Non-Flickering?

anotheruser

Looking to buy some LED bulbs but some state they're specifically non-flickering but others don't.

I have some at the moment from Screwfix that flicker very quickly meaning when moving, it's a bit strange on my eyes.

Found some on ebay but they don't state they're non-flicker but I'm worried it'll be a waste of time. Others on Amazon are more expensive but state they're flicker free.

Just wondering on some advice really.

Thanks

Yes I have LEDs in every room and none of them flicker. BUT it depends partly on your set up - sometimes for downlights, you have to replace the transformers to ones suitable for LEDs.

It tends to the bottom of the range no-brand ones that flicker. Go for brands you have actually heard of.

Hmm.
Well the description suggests, by use of a strange word, they're good so I'll give them a go. EBay job so if they're no good, I'll be able to send them back FOC.

Thanks

The reason for this is the fact that basic transformers such as those used for 12v halogen lamps are 220 to 240v ac input and 12v ac output.
Whist having an alternating output is fine with incandescent lamps which don't get a chance to dim due to the alternating 12v, this isn't the case for LED's.
Because an LED can switch on and off extremely quickly, it will do this 50 times a second which can result in a noticeable flicker.

LED drivers are transformers in which the ac output has been rectified to make it dc so the LED's won't be rapidly turning on and off, so no flickering.
