KSEB plans to clear unsold LED bulbs by offering freebies and distributing them to various institutions and new consumers.

The common items in this case were “filaments” from LED light bulbs, those meant to mimic the look of clear-glass incandescent light bulbs. [Andypugh] had been looking at them with interest ...

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 ...

Incandescent lamps generate light by passing an electric current through a thin filament wire until the wire is white-hot. They are used mainly in residential applications because they emit a warmer ...

which claim to give up to 120 per cent more light than standard bulbs. Our last test focused on the single-filament H7 bulbs commonly found in dipped beam headlamps. This time round, we look again ...

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.

For this method, the more intact the bulb, the better. Begin by cutting power to the light source. If the filament is still intact, use a pair of needle nose pliers to grip the glass base of the ...
