The problem is that the heat from the power supply needs some place to go. So installing the bulb upside down traps heat, and putting them in an enclosure also traps heat. Probably 90% of installations is one of these two.
I've put in some "filament" style LEDs, these look like they will last longer as there doesn't appear to be a power supply taking up half the bulb (although there are electronics down in the screw part).
- Retric 7y agoAt a given efficiency, LED heat and light output are directly related. Human vision is not linear at normal brightness levels. So, less bright bulbs last longer, use less energy, while putting significant amounts of light. Also, I see many people getting extremely bright bulbs and putting a large fully opaque light shade over them. That’s rather counter productive.
