There is a selection of incandescent, compact fluorescent, CFL and LED lights or lamps that are available today.
It is useful to be able to compare the performance of the LED, incandescent and CFL lights so that the optimum choice can be made.
The comparison of LED, CFL and incandescent lamps shows that LEDs normally win out over every type in terms of performance and environmental impact. The only drawback is that the cost is higher, although when taking the running costs over the lifetime, their cost comes out considerably cheaper.
|Comparison of LED CFL & Incandescent Lights|
|Average life (Hours)||50 000||1 200||8 000|
|Power for equivalent of 60W incandescent||6 - 8||60||13 - 15|
|Typical oeprating cost over a year (USD $)||32||330||75|
Environmental Impact Comparison
|Mercury content||Zero||Zero||Contains toxic mercury|
Operational characteristics comparison
|Sensitive to low temperatures||No||Some||May not work below -20°C|
|Sensitive to humidity||No||Some||Yes|
|Effect of on/off cycling||Very little effect||Some||Not very tolerant - reduces lifetime|
|Speed of turn on||Instant||Instant||takes time to warm up|
|Durability||Very durable, can withstand reasonable shock||Not particularly good. filament sensitive to shock and glass envelope can break||Not very robust - glass can break and emit toxic mercury|
