Light bulb adapter
I have an idea for a cheap but useful invention: A light bulb socket adapter that contains 470 nF capacitor to reduce the current going to an LED bulb. For safety you’d also want to bridge the capacitor with a 1 megaohm resistor to discharge the capacitor.
The idea would be to greatly extend the life of the light bulb and significantly reduce power consumption while only slightly dimming the bulb.
But it would worth it even if you had to install brighter or additional bulbs to get the desired output due to greater efficiency. It would produce some reactance but they don’t charge for reactance and the apparent power still would be less.
