Lumens, the unit of luminous flux. A point light source having a luminous intensity of 1 candela (cd), the luminous flux emitted in a unit solid angle (1 steradian) is "1 lumen", the abbreviation (lm).
In simple terms, lumens refers to the brightness of a candle that is outside a meter (1 meter = 1 meter). An ordinary 40-watt incandescent bulb with a luminous efficiency of about 10 lumens per watt, so it can emit 400 lumens of light. When a 40-watt incandescent lamp is 220 volts, the luminous flux is 340 lumens. Luminous flux is the ability to describe the visual response of a source of radiation in a unit of time. The unit is lumens, also known as brightness.
Our company produces 40W LED floodlights with high lumen output and CE ROHS FCC certification, In this year 2017, Senlu lighting has been awarded The Most Influential Brand by Chinese government, and the Golden Brand by Chinese Road Lighting Association.
