Comparison of lighting technologies
Comparison of lighting technologies Here is a comparative study of the different lighting technologies allowing you to make the best choice for your bulbs or projector. 1st criteria: cost In order to compare different bulbs from an economic point of view let's take the following example: A bulb works for 3 hours a day on average over 10 years. The desired light output is equivalent to an 80W incandescent bulb (850 lumens) or a 65W halogen bulb, a 16W compact fluorescent bulb, and a 10W LED bulb . The service life is as follows: Incandescence 1,200h, halogen 2,000h, compact fluorescent 5,000h, LED 20,000h. Update 2018: Table 1 was published in 2014, the cost of a 10W LED bulb is now around 3 to 4 €. Or an additional saving of 12 €. The installation of an LED bulb saves 100 € compared to an incandescent, 78 € on a halogen and 28 € on a flu compact over 10 years. 2nd criteria: consumption or energy efficiency: To measure the performance of a bulb, the rati...
