Hi, I'm new here and still trying to get a feel of the site.
I have a seemingly simple problem. I bought a few "retro Edison" E14 LED bulbs rated for 2W @ 220V. However, they seem to have a very short lifespan and I would very much want to reduce the amount of voltage fed into them. As a side preference, I would also want these to glow slightly less bright. As these are non-dimmable LEDs, using a standard dimmer is probably out of the question.
Our mains sits at 230V on average.
Using a power meter, this is what I gathered when powering one of these bulbs:
Input: 230V / 60Hz
Power: 2W
Current: 0.042A
PF: 0.2
Now, is it possible to use a resistor in series so that the LED will see a lower voltage? What would be the formula for R (resistance value and power rating)?
Thank you.
