How Many Lumens are Needed for Outdoor Lighting
Web26 jan. 2024 · Lumens equal brightness; watts measure energy used. LEDs use much fewer watts than incandescents with the same brightness. As a rule, you’ll replace a standard 75W bulb with an energy-saving bulb of about 1100 lumens. On the low end, replace a 40W bulb with an LED bulb of about 450 lumens. Web22 jul. 2024 · For example, a 100 W incandescent bulb produces about 1,600 lumens, for an efficiency of 1,600/100 = 16 lumens per watt. A halogen bulb, on the other hand, consumes only 72 watts for the same amount of brightness, making its efficiency 1,600/72 = 22 lumens per watt. A CFL bulb consumes even less energy – only 26 W – so its … smal inbouwreservoir
