2. Inrush current - Wikipedia

   en.wikipedia.org/wiki/Inrush_current

   For example, wall switches intended to control incandescent lamps will have a "T" rating, indicating that they can safely control circuits with the large inrush currents of incandescent lamps. The inrush may be as much as 14 times the steady-state current and may persist for a few milliseconds for smaller lamps up to several seconds for lamps ...

3. Incandescent light bulb - Wikipedia

   en.wikipedia.org/wiki/Incandescent_light_bulb

   An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...

4. Current limiting - Wikipedia

   en.wikipedia.org/wiki/Current_limiting

   Foldback current limiting is most likely to be found in a switch-mode power supply when it is a component in a product that is independently certified to meet regional safety standards. [2] The inrush current of an incandescent lamp causes a bench power supply to limit its output current with a foldback current limiter.

5. Inrush current limiter - Wikipedia

   en.wikipedia.org/wiki/Inrush_current_limiter

   An inrush current limiter is a component used to limit inrush current to avoid gradual damage to components and avoid blowing fuses or tripping circuit breakers.Negative temperature coefficient (NTC) thermistors and fixed resistors are often used to limit inrush current.

6. Multifaceted reflector - Wikipedia

   en.wikipedia.org/wiki/Multifaceted_reflector

   With both types of incandescent bulbs, useful life can be considerably shortened if their filaments experience mechanical shock or vibration. Using an electronic transformer with a soft start feature can considerably extend life, as it reduces the characteristically high inrush current that occurs initially when the lamp is cold. Dimming also ...

   America’s ban on incandescent light bulbs, 16 years in the making, is finally a reality. Well, mostly. A rule issued in 2007, rolled back by the Trump administration, and updated last year by ...

8. These are the best — and worst — lightbulbs for the planet

   www.aol.com/lifestyle/best-worst-lightbulbs...

   Over a decade, the original incandescent bulb and its replacements will cost about $93, whereas over the same stretch of time, that LED bulb will cost $19.45 — as just one LED bulb can last up ...

9. Electric light - Wikipedia

   en.wikipedia.org/wiki/Electric_light

   When an electric current is connected, the tungsten is heated to 2,000 to 3,300 K (1,730 to 3,030 °C; 3,140 to 5,480 °F) and glows, emitting light that approximates a continuous spectrum. Incandescent bulbs are highly inefficient, in that just 2–5% of the energy consumed is emitted as visible, usable light.
