The old days of choosing light bulbs by wattage are over. With today’s modern LED bulbs, we instead need to focus on lumens. But what is a lumen? We’ll explain that, and then you can use our lumens to watts conversion chart to select the right LED bulb every time. ...
Lumen comparisonHow many lumens are in a watt will depend on the type of bulb used in a lighting fixture. On average, old tungsten incandescent light bulbs will produce 15 lumens per watt while efficient LED bulbs will produce about 75 lumens per watt....

There is an opinion that the brighter the light is, the better it is. Well, it depends on a situation. For instance, if you are looking for a good light for work, over 8,000 lumen is not a good idea because the reflection is going to blind you and it may affect the working effic...
1000 Watt Metal Halide LED Replacement by Dwayne Kula | Apr 12, 2019 What Does it Take to Replace 1000 Watts Metal Halide with LED? Before LED lighting became the powerhouse that it is today, metal halide lights were the most common form of lighting in commercial... read more Lumen Depr...
where LE is the lumen equivalent of the spectral power distribution. FIG. 1B shows how the impact of a light source on the circadian system scales against light intensity. The impact of a light source on the circadian system scales with relative CS, with light intensity (e.g., lux level...
temperature will rise rapidly and output will decrease rapidly since heat is lost less quickly in higher ambient temperatures. Thus wattage required to maintain 30 fc will increase rapidly and lumen output per watt will decrease accordingly. Also, the thermal equilibrium point will be higher, which...
