An LED 'Filament' Bulb: Not a Contradiction

For those who miss the appearance and glow of a filament-based bulb, this LED bulb technology may offer the best of both worlds. It’s not news that the venerable incandescent-based bulb with its glowing filament is on the way out. Due to technical advances, regulatory mandates, and substantial cost savings, compact fluorescent lamps (CFLs) and especially LEDs are taking over the lighting world in residential, commercial, and industrial settings. Still, there are many who long for the glow of that filament. Reasons vary: For some, it is nostalgia for their youth; for others, it’s the hip, retro factor; and for others, there’s something almost primal about that glow, reminiscent of elemental fire (the glowing filament is certainly analogous to that).
