Simply put: a LED light uses far less energy (watt) to produce the same light output (lumen). An example: a LED bulb uses only 2.5 watts to produce a light output of 115 lumen, while a traditional bulb uses 15 watts (or 6 times more energy!) to produce the same lumen output. Watch the video to learn more about watt and lumen, or check out our

So it would take only 100 hours'' worth of electricity to buy one equivalent, energy-saving lamp. For the sake of easy math, let''s say an energy-saving lamp equivalent to an old-style 100 watt lamp uses 20 watts and lasts for 10,000 hours (so it will use five times less electricity and cost only a fifth as much to run).
