WebFluorescent Light Bulb: (15/1000) 12 hrs (10/100) = 0.018 0.12 - 0.018 = 0.102 A 75-watt light bulb produces 5 watts of radiant energy and 70 watts of heat energy. What is its efficiency? A) 0.0667 B) 0.0714 C) 0.0093 D) 0.9333 A) 0.0667 5/75 = 0.0667 Higher Wattage bulbs are less efficient than lower Wattage bulbs. A) True B) False B) False WebP(W) = ΦV(lm) / η(lm/W) So watts = lumens / (lumens per watt) or W = lm / (lm/W) Example What is the power consumption of a lamp that has luminous flux of 900 lumens and luminous efficacy of 15 lumens per watt (lm/W)? P = 900 lm / 15 lm/W = 60 W Luminous efficacy table Energy saving lamps have high luminous efficacy (more lumens per watt). WebThe old technology of tungsten incandescent bulbs only had an efficacy of about 15 lumens/watt. Depending on the bulb and the manufacturer, LED technology typically produces 75-110 lumens/watt. So, LEDs are generally about 7 times more efficient at producing light than incandescent bulbs. shuttle sky harbor to prescott
