You have a need for a capacitor in a circuit, well that capacitor needs to handle not the average voltage or the RMS voltage it must withstand the peak voltage. Same with insulation, you need to allow for the peak/peak-to-peak voltages or a 0reakdown will occur.
When selecting a capacitor for LEDs, it is important to consider the voltage rating. Each capacitor comes with a maximum voltage rating, so factor in the amount of voltage applied across the capacitor to ensure suitability.
Capacitors are used in LED drivers to smoothen and reduce the ripple coming from the power supply. Selecting the right capacitors for LED lighting systems helps in avoiding flickering, eliminating excessive heat, and ensuring longevity of the LED lights.
If you install a capacitor across a light switch, there will be voltage present on the line, and some current through the attached incandescent, starter-based flourescent, and maybe LED lamps, as well as motors. Why can’t we use a capacitor at home for lighting or heating?
For general lighting applications including ballast kits and sign lighting, choose a dry capacitor. These HID capacitors operate in temperatures up to 221 degrees Fahrenheit. Oil filled capacitors are used in applications that require higher power and voltage, such as stadium, horticulture, and industrial lighting.
The Wikipedia page also contains a photo of an LED bulb with what to all appearances seems to be a capacitive supply. There is no reference given as to who’s LED bulb this is, but the text mentions a 1.2 uF capacitor providing 90 mA powering 48 white LEDs, apparently divided into four branches of 12 that each use 20 mA.

Get PriceYour electricity delivered to your house actually varies from about 110V to 126V which may be dependent on where your house is, and can also vary somewhat during the day. You used to be able to buy a resistor to use with incandescent lights, say to convert a 100W light bulb to 60W output.
Get PriceLighting circuits are usually on a 6A MCB or 5A fuse, though 10A can be used (with some extra restrictions (now removed in the 17th edition of the wiring regs)) for large circuits. However if the area served is large, more 5A or 6A circuits would in most cases be preferable. lighting circuits are typically wired in 1mm² or 1.5mm² T&E cable (1.5mm² allows a longer cable run, before …
