Using LEDs as mains indicator lights on 120V and 230V (live demos) – YouTube

Posted by jpluimers on 2020/07/28

I love the “bigclive” YouToube channel: it is full of neat ideas, and wise tips on disassembled electrical gadgets. Most of his videos involve soldering or/and making schematics of the things he tears apart or builds.

This one is on Using LEDS as mains indicator lights on 120V and 230V (live demos):

Modern LEDs are bright enough at low current to use as directly mains powered indicators with minimal circuitry. The slight downside is that with a simple resistor circuit the vast majority of the power gets wasted as heat. But the current is so low anyway that it doesn’t really matter. Here are some simple ways to drive LEDs from 110V to 240V with minimal circuitry. I tend to recommend running resistors at around half their rating at worst as it means they will last a long time and not discolour too much with age.

His [WayBack] bigclive.com web-site is very small and shows some of his projects.

You can follow him on either youTube or on the the BigCliveDotCom reddit channel.
