Very nice 1W LED filament lamp (Patreon)

I'll start by saying that in the UK the term "festoon lighting" means a cable with lots of lamps spaced along it. Very popular for ambient outdoor lighting in gardens and at outdoor events. I've since realised that the seemingly inefficient design may actually be to allow this lamp to operate from 100V to 240V. In fact, on a 100-120V supply it will run so cool (0.5W total) that it will have a massively long lifespan. This lamp is a very golden white 1W single LED filament globe and looks visually very pleasing, with no flicker and a soft glow. It turns out that the filament is only passing about 2.5mA and dissipating 0.3W, so the bulb should last for ages. (There - I've managed to say, lamp, globe and bulb to please everyone.) The circuitry is entirely as expected, but disappointing in that the lamp could have run two filaments for double the light for the same power dissipation on a 220-240V supply. On a plus note, the hideously inefficient design means that these lamps will handle a wide voltage range. My resistor hack would have made it less suitable for the wider voltage range, although it would still have lit, albeit at a much lower intensity on 120V. Mid-play video-adverts are annoying in technical videos, so I don't enable them.

That also lets you critique the (advert free) videos before they are released, gives a more direct means of communication with me and also gives access to the regular relaxed Patreon live streams. https://www.patreon.com/bigclive #ElectronicsCreators
