The answer would be a combination of the right filament material and using an evacuated bulb to prevent the filament degrading. But it took over a century to get a commercially successful lightbulb.

LIVERMORE, Calif. — Follow a leafy suburban street past churches and chain pizzerias. Walk into a worn-down firehouse and ...

[Discrete Electronics Guy] built a plasma bulb using the casing from an old filament bulb and an ignition coil connected to a high voltage power supply. The power supply is based on the 555 timer IC.

Use precise geolocation data and actively scan device characteristics for identification. This is done to store and access ...

A new study from the University of Michigan (UMich) researchers sheds light on a light bulb that looks similar to an ordinary ...

We tested the low-beam performance of single-filament (9003) and dual-filament (H7) bulbs from GE, Hella, Philips, and Sylvania, and PIAA's dual-filament bulb. We also compared their performance ...

Salisbury EcoHub Alliance will be handing out LED low-energy lightbulbs at their Tuesday market stall from March 25.

Plot a graph of voltage, V on the y-axis v current, I, on the x-axis. For a filament bulb, voltage and current are not directly proportional as the graph is not a straight line through the origin.

The bulb glows because electricity flows through the thin wire inside the bulb called a filament and makes it hot. When the bulb gets old, the wire will eventually break, breaking the circuit and ...
