These are NOT incandescent light bulbs!
Note that these are not true 60W incandescent bulbs. Rather, these bulbs contain a 43W Halogen capsule instead of a filament, making them Halogen (and not incandescent) bulbs. This limits their usefulness and lifespan, and they should not be used in recessed or sealed enclosures due to heat concerns and the risk of rupture. Halogen bulbs operate much hotter than a typical incandescent, CFL or LED bulb.
These bulbs are also unsuitable for use in older home fixtures where the house wiring is rated at 60 degrees Celsius (rather than the modern 90 degree requirement). This increases the risk of insulation breakdown due to heat exposure and presents a significant fire hazard.
