I have a bucket of dead tuya bulbs. I figured I’d give em a go in the string lights for the Halloween party before tossing em. I shocked the crap out of myself with one of them (with an audience) but the shock turned the no longer wifi bulb red. I call it a win.

In reply to Tony M. If I had a CNC mill, I would definitely make some water blocks and play around with some very high power, water cooled LEDs. Water cooling is certainly overkill for room lighting though. Lots of LEDs spread out on an aluminum strip or sheet works great for that and stays cool.

I would actually expect that it is the race to the bottom for pricing, your average consume sees two bulbs in the store – one for $4- and the other for $3- most will go for the $3- one – so many manufactures just keep making things cheaper and thus the less reliable cheaper wins the race

none of the six LED can spotlights in the ceiling of my kitchen have ever been replaced, and they date to the very first generation of LED lighting, back when you had to buy LED bulbs online from specialty stores. when was that, 2010 or so? they were about $20 each at the time.

In reply to Andrew. More liberal “green” lies… everyone smart knew this would be the result. Nuf said…

I’ve started writing the date of purchase and date of installation on all my bulbs, and keeping the receipt with the box. That way I can hold them to their 5-year guarantee! Eventually they’ll start making better bulbs (or lower their guarantee), or I’ll get free bulbs for life…

Sometimes I discover myself wandering about my ideal LED lamp with a custom made water based cooling system, probably made of copper or aluminum, using the same yellow liquid cars use to cool the engine, with internal path ways for each LED, or maybe a similar system to that laser epilators use to cool the lamp/diode. and some kind of logic to control temperature levels and a very well designed PMPS with all the elements needed to protect the entrance from surges…and a simple ON/OFF swith (not that smart things connecting to some uknown server)

But then I remember I don’t have a CNC, I don’t know 3D modeling and I have no time to design the PCB :) so I go to my local store and buy an el cheapo one.

sooo, it would be an interesting project, it would last forever, but spending a ton to replace a bulb…
