This Classic Globe from Integral LED uses just 6.6W but serves a direct replacement for 40W filament bulbs. Its frosted finish makes it completely indistinguishable and enables it to produce that familiar, warm white light that is perfect for living rooms, hallways and bedrooms, though the LED technology it obscures can potentially reduce your lighting bill by up to 90%.The bulb\'s body is constructed from an aluminium and plastic composite that dissipates heat away from its essential components more effectively than comparable materials, thereby placing them under less strain and extending the bulb\'s lifetime. Ultimately, this LED globe won\'t need replacing nearly as much as your existing incandescent versions and can yield substantial savings when considered alongside its markedly superior efficiency.To guarantee complete dimming compatibility, we recommend pairing this bulb with a trailing edge dimmer switch.
