I've been installing Kauf brand smart-bulbs, which come pre-flashed with ESPHome for integration with Home Assistant. Some of my earlier bulbs failed, and I recently noticed that the founder of the company commented on the issue and said he specced a more robust capacitor after early failures: https://github.com/KaufHA/kauf-rgbww-bulbs/issues/31#issueco...
I haven't contacted them for replacements yet, but seeing their comment makes me much more likely to purchase them in the future, despite my early issues.
Thank you for making me aware those exist. I have a mix of Hue & cheap Walmart color wifi bulbs. The Hue bulbs are undoubtedly much high quality (in both output & reliability) but you pay for it. The Walmart ones are 1/5 the cost, but very hit & miss on whether you can easily flash tasmota/esphome - and there is no way of knowing until you try because of newer firmwares being shipped in the same packaging.
