The brightness of a light bulb used to be measured in watts. Today we calculate in lumens and the unit watt only stands for power consumption. Here is a comparison table to help you rethink.
Incandescent lamp Watt: | 25 W > 220 lm | 40 W > 415 lm | 60 W > 710 lm | 75 W > 930 lm | 100 W > 1340 lm |
Energy-saving lamp Watt: | 5 W > 250 lm | 8 W > 425 lm | 11 W > 600 lm | 18 W > 1100 lm | 23 W > 1400 lm |
Halogen ECO Watt: | 18 W > 204 lm | 28 W > 370 lm | 42 W > 630 lm | 53 W > 850 lm | 70 W > 1200 lm |
LED Watt: | 2.5 W > 250 lm | 4 W > 470 lm | 7 W > 806 lm | 8 W > 1055 lm | 11 W > 1521 lm |
LED | Incandescent lamp | halogen | |
2-3 Watt | equivalent to | 25 watts | 20 watts |
4 watts | equivalent to | 40 watts | 30 watts |
7 watts | equivalent to | 60 watts | 45 watts |
8 watts | equivalent to | 75 watts | 60 watts |
11 watts | equivalent to | 100 watts | 75 watts |
The values given are approximate values that may vary depending on the type and design of the light source. The value is influenced by factors such as matt or clear, dimmable or non-dimmable, beam angle, lamp shape (spot, reflector, mirrored) and manufacturer.
