It is difficult to compare the brightness of LED bulbs with conventional bulbs (incandescent and/or fluorescent) since the brightness of LED bulbs is not directly related to watts ( bulb power) of the same, as if they were conventional light bulbs.
In LED bulbs, the watts only reflect their consumption and not their quality and quantity of luminosity, which in this case is measured by the international unit of luminosity (Lúmen or Luxes) commonly represented as “Lm”, therefore through the relationship between power consumed (Watts) and the quality of luminosity (Lumen) we can determine the “luminous efficiency” (Lm/W), where “Lm” is the amount of light emitted by the < strong>LED bulb and “W” is the power consumed by the LED bulb.
In the following equivalence table we can see the luminosity relationship between LED bulbs and other types of bulbs taking into account their consumption in watts (W):
Lumens (Lm) | LED | Incandescent | Halogen | CFL and Fluorescents |
80/110 | 1 W | 10 W | – | – |
110/270 | 3 W | 30 W | 20 W | 7 W |
250/450 | 5 W | 40 W | 35 W | 13 W |
550/720 | 7 W | 60 W | 50 W | 15 W |
650/800 | 11 W | 100 W | 70 W | 23 W |
800/1500 | 15 W | 120 W | 100 W | 32 W |
1600/1800 | 18 W | 150 W | 150 W | 48 W |
2500/2600 | 25 W | 200 W | 200 W | 52 W |
2600/2800 | 30 W | 250 W | 250 W | 68 W |
Consumption equivalence
Therefore, in addition to mentioning the brightness equivalence between LED bulbs and conventional bulbs, it is also important to highlight the consumption equivalence between LED bulbs and conventional bulbs.
In the following tables we can see the consumption equivalence between LED bulbs and conventional bulbs in their different presentations:
Consumption in Watts (W) Conventional bulbs | Consumption in Watts (W) LED Bulbs |
20 W | 4 W |
40 W | 5/6 W |
50 W | 7 W |
60 W | 9 W |
80 W | 12 W |
100 W | 15 W |
Consumption in Watts (W) Conventional reflectors | Consumption in Watts (W) LED Reflectors |
100 W | 25 W |
250 W | 75 W |
400 W | 150 W |
500 W | 200 W |
Consumption in Watts (W) Conventional Downlights | Consumption in Watts (W) LED Downlights |
52 W | 24 W |
75 W | 30 W |
150 W | 45 W |
Equivalence in Watts (W) between Tungsten/Halogen bulbs and LED bulbs: Tungsten/Halogen bulbs/PAR type: MR11 – MR16 – GU10 – E- 14-27
Power | LED equivalence |
10 W | 1 W |
20 W | 3 W |
35 W | 5 W |
50 W | 7 W |
60 W | 10 W |
80 W | 12 W |
100 W | 15 W |
It should be noted that LED bulbs offer a more pleasant amount of luminosity than that not offered by conventional bulbs, in addition the thermal sensation is also better and as if that were not enough, the consumption of electrical energy is lower, so Without a doubt, LED bulbs are currently the best option for illuminating places both indoors and outdoors. However, they usually have a somewhat high price, which is understandable due to their quality, but despite that the price difference between LED bulbs and conventional bulbs is not as big as so as not to replace the already traditional incandescent, fluorescent, halogen, tungsten and other bulbs with these new bulbs.
