I did keep the Temu 120V bulbs (and did the hack) (Patreon)

Modifying Temu LED bulbs - really neat circuitry

Having ordered a box of what I thought were going to be at least 220V (Chinese voltage) bulbs I was a bit disappointed when they arrived and were 120V. I ended up keeping them, and I'm glad I did as the design is minimalist and interesting, making it quite easy to modify them. The filaments are actually using phosphor on blue LEDs to match the globe colour, which helps make up for the inefficiency of the circuitry. This is the first time I've seen such a minimalist approach, where the resistor leads aren't just the connection to the base, but also support the filament. If I'd had some here I'd have used half watt resistors, but all I had were quarter watt or 1W in that value. The half watt resistors would have fitted into the plastic sleeves better, although I'm not sure how wise it is to have hot resistors stuffed into a plastic base like that. In higher voltage countries they could have made a two filament "vee" for much higher output and efficiency. I'm quite tempted to do that by merging two bulbs into one. There is a dedicated video just about the lamp base crimping tool. It's used to pinch the metal into the base of plastic globes:- https://www.youtube.com/watch?v=Y5N24xvDEkM If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- https://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty. #ElectronicsCreators
