Long Lasting was a US labeling for (now older) Tungsten based bulbs that got their 'Last' by running a cooler filament . (Less Light for watts input)
Lumens (per watt), tells the story
Funny thing,
The All Knowing regulators ignored all the edge cases where electronic or (
consumer) fluorescent technology is unworkable.
HOT Locations:
Ovens and Attics for example. Basically any place an unprotected Human can stay for > 30 minutes.
Totally enclosed (glass, or plastic). Read the markings on the bulb
The electronics inside still generate some heat, and must keep cool (<60-80C)
Really COLD Locations. (LEDS do Work in far colder areas)
CFL, or regular fluorescent need special fixtures to start reliably much below 40F (4.5C). They will run (after a start) in colder areas.
In colder locations, the electronics needs to be kept warm or starting and voltages control may suffer.
