Speaker 1: Welcome to brain Stuff from house stuff works dot com

2
00:00:03,640 --> 00:00:07,800
Speaker 1: where smart happens. Hi. I'm Marshall Brain with today's question,

3
00:00:08,240 --> 00:00:12,440
Speaker 1: are fluorescent bulbs really more efficient than normal light bulbs?

4
00:00:13,000 --> 00:00:16,680
Speaker 1: A normal lightbulb is also known as an incandescent light bulb.

5
00:00:16,920 --> 00:00:21,200
Speaker 1: They typically come in size is like six D and

6
00:00:21,239 --> 00:00:23,920
Speaker 1: so on. They waste a lot of energy on heat,

7
00:00:24,000 --> 00:00:28,040
Speaker 1: so they're not very efficient. They produce maybe fifteen lumens

8
00:00:28,120 --> 00:00:31,880
Speaker 1: per what of input power. A fluorescent bulb uses a

9
00:00:31,920 --> 00:00:35,960
Speaker 1: completely different method to produce light. A fluorescent bulb produces

10
00:00:36,120 --> 00:00:39,480
Speaker 1: less heat, so it's much more efficient. A fluorescent bulb

11
00:00:39,520 --> 00:00:42,560
Speaker 1: can produce between fifty and a hundred lumens per what.

12
00:00:43,240 --> 00:00:46,320
Speaker 1: This makes fluorescent bulbs four to six times more efficient

13
00:00:46,360 --> 00:00:49,520
Speaker 1: than incandescent bulbs. That's why you can buy a thirteen

14
00:00:49,600 --> 00:00:52,680
Speaker 1: watt fluorescent bulb that produces the same amount of light

15
00:00:52,960 --> 00:00:56,520
Speaker 1: as a sixty what incandescent bulb. Do you have any

16
00:00:56,560 --> 00:01:00,240
Speaker 1: ideas or suggestions for this podcast? If so, please send

17
00:01:00,240 --> 00:01:03,600
