I know that LED's only work in one direction and therefore AC bulbs tend to be prone to strobing. I'm particularly sensitive to this. If I put one in a table lamp without the shade and wave it around you can literally see the on off flashing. I have tested this out with a number of bulbs (albeit inexpensive LEDs) and they all have the same effect.

I want to fit 12 x 5W LED's into a chandelier designed for E14 bulbs, and wondered if there was a way (perhaps with the use of a capacitor, or other electrical device) to smooth out the flashes to an acceptable level. I know that some of these bulbs have capacitors built into them, but I presume they go into the low voltage side of a step down transformer. Any electrical experts please do advise.

Many thanks, Jon.

It really depends on how the lamps are constructed and more precisely the value of the components in the light. Often cheap lights just have a basic capacitive dropper to run them. (No transformer or smoothing capacitor at all) By doing this the costs are kept down. All I can suggest is you try several brands of lamp until you find one you are happy with, I really do wish it was easy as saying "yes add this value capacitor, this choke and oh, a diode here and away you go", but its all down to what is in the actual lamp.


As an aside LED's do run on DC, but they will also run on AC, if you use a high enough value resistor you can connect a single LED across the mains, but yes it will flash at 50hz. its not to be recommended though.

Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?
