For track lights, the bulb is one of the key factors that determine its lighting effect. With the popularization of LED technology, more and more track lights have begun to use LED bulbs as light sources because LED bulbs have the advantages of high energy efficiency, long life, low heat, and environmental protection.

Luminous efficacy (lm/W) = Luminous flux (lm) ÷ Power (W) For example, if the luminous flux of an LED bulb is 800 lumens and the power is 8 watts, its luminous efficacy is: Luminous efficacy = 800 lm ÷ 8 W = 100 lm/W

Light+Building 2022 successfully ended in Frankfurt Exhibition Center on the 6th of this month. 1531 exhibitors from 46 countries showed many innovative products and solutions to the world
