The traditional light bulbs transform only 5% of the energy received, and the remainder is lost, while the fluorescent bulbs, on the other hand, transform 25%, while Commercial LED Lighting provide even 50%. LED bulbs, halogen, low consumption and energy saving.
These differences in the transformation of electricity obviously affect consumption. First of all, we must no longer look at the power, indicated by the Watts, as it was used with old incandescent bulbs, but at lumens, the unit of measurement of the luminous flux of a light bulb. Therefore, 1 100 W incandescent bulb can be replaced by 1 20 W LED with an average duration of 5,000 to 15,000 hours. So Sydney Lighting Design can calculate the annual cost compared to an incandescent bulb.
Fluorescence: 60-80% thanks to a duration of 4.00-8.000 hours, with an annual cost of about 4.20 dollars. LED: 90%, with a duration of 5,000-10,000 hours and an annual cost between 2.70 and 4.20 dollars depending on the power chosen.
