A higher wattage does not mean a brighter light anymore. This is why the unit “watt” is no longer an accurate measure of brightness for today’s light bulbs. Then how about other types of light bulbs such as halogen and CFL? These comes with another range of luminosity per watt.

Back then, these bulbs came in standard 16 lumens per watt so a description in terms of watt would be enough to illustrate the brightness of the bulb.Ī higher wattage does not mean a brighter light.īut today, especially with the emerging LED technology, we can get bulbs as efficient as 250 lumens per watt! Not to mention fluorescent bulbs which produces light intensity of between 50 to 100 lumens per watt. This question would be easy to answer decades ago when incandescent light bulb was the only household norm. Lumen is the measure of light intensity while watt is the measure of power needed to operate the light. We always hesitate to answer this question because watt is not equivalent to lumen. Every once in a while we get customers asking, “what is the watt equivalent of this lumen?” If you haven’t noticed, we always describe the brightness of our solar lights in unit “lumens” instead of “watts”.
