Another bulb - but an interesting one
Added 2024-09-15 03:29:39 +0000 UTCI added this to an aliexpress order just for the novelty value, but it's actually quite neat.
The housing is made from two parts that clip and glue together around a flexible filament with 200 LEDs. The power supply uses a different chip I haven't come across before.
Comments
The minimum LED voltage is FAR too high (275-300V) for it to be usable on 120V (it won't light) so it clearly designed exclusively for 220-240V as the item listing say. Small (E14) and medium (E27) Edison sockets are THE standard light bulb fitting in pretty much all 230V countries other than the UK AFAIK (it's not just the sockets that are, well, different).
