I was wondering how long it would be before the LED candle flame PCBs would end up inside a glass bulb.  The result is very good.  Lower power, better colour and brighter than the classic neon version.

New LED flame bulb - with schematic

The neon based flicker-flame bulbs have been around for a very long time, and although they were an interesting effect, they tended to be a bit unconvincing. So now it's time for the LED version with a much better emulation of a flame. The power supply is very typical of the type found in smart bulbs to provide a 3.3V supply to the WiFi and Bluetooth modules. In this case the 3.3V just happens to be the perfect voltage for powering the microcontroller and the LEDs. It's actually perfect for powering many LED bulb projects, but note that it is not isolated from the mains supply. The flame PCB has a surface mount 8 pin microcontroller and 32 flip-chip LEDs on one side, and then a layer of phosphor gel added on both sides. The globe itself has a traditional glass construction, with the filament support bonded to the PCB and the small power supply in the base. Here's the only listing I found for these in the UK:- https://www.ebay.co.uk/itm/355271559068 Shout out to a friend called Richard for letting me know these exist.

I've featured that style in the past (and even managed to upset a Chinese manufacturer when I showed their PCB). That type is very mass produced now.

Some cool LED flame lamps in a mostly glass envelope have been around for several years but have been hard to find. Here's an example: https://www.amazon.com/gp/product/B08789LJPS The flame effect is very good because both the side to side and bottom to top flame motions are modeled in software and repeated on three sides. There used to be a portable rechargeable lamp that used a larger bulb like this with even more LED's (282 of them I think, I have a few of them, $90 each) but the company seems to have stopped making them. Probably too much competition from the cheaper flame lights. It was one of the first LED flame lamps and the flame effect was superb, behind frosted glass it looked real and never repeated its pattern as far as I could tell. I think they had a patent on the idea. This page from Euri Lighting says some of their lamps have over 300 LED's: https://www.eurilighting.com/product-category/residential-lighting/general-purpose-lighting/decorative/flame-lamp/
