LED, CFL & Incandescent Lights Comparison

LED, CFL & Incandescent Lights Comparison


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.
