How is light output measured

Web7 jan. 2024 · The average LED light temperatures range from 2700K (warmest) to 6000K (coolest). While a 2700K bulb will cast a cozy, orange glow and a 6000K bulb will emit a crisp, blue light, the brightness will nearly be the same. Changing from 4000K to 5000K will typically only increase brightness by 20-60lm, in the same fixture, of course. WebThe easiest way to check this is to remove an existing lamp and examine the pins on the end of the lamp, and measure the distance between the pins to determine the pin specification. The most common type for T8 and T12 lamps is the G13 bipin (0.5 inch / 13 mm apart), and T5 lamps is the G5 bipin (0.2 inch / 5 mm apart)
