Welcome to brain Stuff from house stuff works dot com where smart happens. Hi. I'm Marshall Brain with today's question, are fluorescent bulbs really more efficient than normal light bulbs? A normal lightbulb is also known as an incandescent light bulb. They typically come in size is like six D and so on. They waste a lot of energy on heat, so they're not very efficient. They produce maybe fifteen lumens per what of input power. A fluorescent bulb uses a
completely different method to produce light. A fluorescent bulb produces less heat, so it's much more efficient. A fluorescent bulb can produce between fifty and a hundred lumens per what. This makes fluorescent bulbs four to six times more efficient than incandescent bulbs. That's why you can buy a thirteen watt fluorescent bulb that produces the same amount of light as a sixty what incandescent bulb. Do you have any
