NettetEnergy saving lamps have high luminous efficacy (more lumens per watt). The luminous flux ΦV in lumens (lm) is equal to the power P in watts (W), times the luminous efficacy η in lumens per watt (lm/W): ΦV(lm) = P(W) × η(lm/W) Watts to lumens calculation See also Lumens to watts calculator Watts to lumens calculation Lux to lumens calculator NettetYou can use this to calculate the diameter of different sized LED tube lights. Therefore, T8 tubes at 1-inch (25.4mm) have a larger diameter than T5 tubes (5/8-inch or 15.9mm), but they are not as wide as T12 (1.5-inches or 38.1mm) lamps. In standard fluorescent tubes, smaller diameters almost always mean better efficiency. locator form for egypt
