Lamp technologies are evolving to meet
new global demand for efficient light sources. Electroluminescence,
induction lighting, compact fluorescent (CFL) and LED
all hold great promise but are not without pitfalls. Incomplete
and often incorrect information lead to misconception
and incorrect application.
For instance: |
- Compact Fluorescent Lamps (CFLs) produce more visible
light per watt, have substantially longer lamp life
and are widely recommended as an energy-efficient substitute
for the standard incandescent lamp. However, when used
in an airtight recessed housing in an inverted, vertical
burn position (upside down) lamp life is greatly reduced.
- Rated lamp-life of pin-based CFLs is based on 3-hour
operating cycles - shorter cycles dramatically reduce
lamp-life.
- In lighting applications LEDs were originally thought
to produce very little heat. However, LEDs are powered
by the computer chip they’re attached to and development
to improve light projection created heat at the point.
Heat dissipation is now an overriding issue with light-projecting
LEDs, often requiring substantial heat-sinks.

| Compact Fluorescent Lamps |
Compact fluorescent lamps with socket on one end
designed for smaller, non-linear applications –
CFLs.
|
| Electroluminescence |
Light source produces light when phosphor crystals
are excited by being exposed to electric current.
Also known as Light emitting Capacitor (LEC).

| Induction Lighting |
Similar to fluorescent, phosphors emit visible photons
when excited by electrical current induced by an electromagnetic
field.

| LED |
Light-emitting diode
