It has become common and ingrained in our minds to think of how bright a light bulb or light fixture is based on its wattage. For example, defining the brightest LED bulb for garden lights can mean finding a bulb with the highest lumens. Because lumens measure brightness and watts measure energy output, there is no simple method for converting wattage to lumens. 25 Watt in Lumens Type of bulb 200-300 lumens 1000-1250 lumens Incandescent 25-30 watts 120 watts Halogen 18-25 watts 100 watts CFL 5-6 watts 20 watts LED 2-4 watts 10-13 watts One may also ask, how many lumens is a 150 watt flood light?
