What does all this jargon mean? |

Amps/Ammeter - A measure of how much electrical current is flowing through
a circuit. (When multiplied by voltage gives the wattage of the lamp). CFL - Compact
Fluorescent Lamp, a type of lamp made of fluorescent tubing twisted in such a
way as to make it compact and suitable for use in place of conventional
bulbs. These are more efficient than incandescent lamps and are therefore
also known as energy-saver lamps or eco-bulbs. Incandescent Lamp - A conventional
light bulb which works by a high resistance filament getting so hot it gives
off light. Kelvin Rating - Referred to on the packaging of
bulbs, this indicated the color of the bulb. (E.g. a rating of 2700K is a
warmer yellow colour while a rating of 6400K is a
cooler white colour.) L.E.D - Stands for Light Emitting Diode. A
circuitry component which is highly efficient in light output,
comes in a variety of colours and can be used in
place of regular bulbs. Lumen/Lux - A
measure of light output. Lux refers to the amount
of luminosity (lumen) per square meter. Power Factor - A rating of how
“together” current and voltage are when they arrive at the bulb.
A rating of 1 means they are completely in phase while a rating of 0 means
they arrive out of phase. When the power factor is low the amount of current
drawn is actually higher and this current must be generated. However, you are not charged for using this extra
power. For more on this see Further Reading. Switching Cycles - refers to the number of times a
bulb is turned on and off during the day. Watt Rating - (e.g. 20W, 100W) the amount of
power drawn by an appliance, in this case the bulbs, the higher the number
the more power is drawn by the bulb. |
