(The wedge bases are now usually not even supplied with the bulbs, which cost nearly as much as buying a new set, typically 10 bulbs for a dollar but a new set of 100 for two dollars.) Modern sets typically have a long and thin wedge that extends all the way down to the back end of the socket, separating the two electrical conductors and ...
These lamps use a bi-pin connector for power: 12-volt MR11 bulbs usually use a GU4 base, and 12-volt MR16 bulbs usually use a GU5.3 base. The common 12-volt MR16 lamps, therefore, require a ferromagnetic or electronic transformer —sometimes misnamed as a ballast —to convert the 120- or 230-volt mains voltage to the extra-low voltage ...
A very small low-power dummy load such as a ceramic power resistor or 10-watt light bulb can be attached to the supply to allow it to run with no primary load attached. The switch-mode power supplies used in computers have historically had low power factors and have also been significant sources of line interference (due to induced power line ...
Simple LED (Light Emitting Diode) circuit diagram. In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
GY6.35 & GZ6.35 – same as G6.35 and only denote what lamp mount clip is needed to hold the actual light bulb in place; G8 – 8 mm (0.31496 in) pin spacing GU8 – same as G8 and only denotes what lamp mount clip is needed to hold the actual light bulb in place; GY8.6 – 8.6 mm (0.33858 in) pin spacing; G9 – 9 mm (0.35433 in) pin spacing

Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure.
