The anatomy of a smart bulb
I&#x27;m really disappointed with all the LED lights I tried (except one brand that doesn&#x27;t exist anymore). Led lights were supposed to last 10 years at 8h per day. Initially they were expensive, but it was possible to get LEDs of good quality. 7 years ago when I was building my house I bought 100 gu10 7W 550 lumen cool white &quot;halogen style&quot; 240V led lights. In these 7 years I replaced around 16. Many of these lights are used 16+ h&#x2F;day. I&#x27;m very happy with them. Unfortunately the brand dissappeared (it was a reseller brand).<p>Since then ever single LED I bought failed with a year or two. Big outdoor led floodlights 25W,50W and few 100W. Every single one fails in a couple of months. They&#x27;re not even used that much as they have PIRs, maybe they are on 20min per day. Then there are E17 lights I bought for a small workshop (12 of them). None lasted over 6 months (used few hours per week in an unheated workshop). I&#x27;m not even buying the cheapest LEDs. It&#x27;s the same regardless if I pay for &quot;premium&quot; or the cheapest.<p>I have so many broken LEDs I started fixing them. I have a hot air soldering station and a pcb heating tool. They always fail the same way. One of the LEDs is burned. Why? Because they are driven too hard that&#x27;s why. If they were driven with 10% less power they would have a chance to last.
