The number of Watts is the energy consumption of the lamp. The number of Watts is the consumption per hour. A 60W lamp that is on for 10 hours therefore consumes 60 x 10 = 600 Watt hours What are lumens? Lumen is a unit of light output. The higher the number of lumens, the more light the lamp emits. This has nothing to do with the colour of the light. To compare lamps, it is best to compare the number of lumens. The greater the number of lumens, the higher the amount of light. amount of light (lumen) incandescent bulb energy consumption (W) compact fluorescent lamp energy consumption (W) our LED lamp energy consumption (W) 100-150 15W 200-250 20W 4W 3W 300 25W 5W 4W 400-500 40W 9W 5W - 6W 700-850 60W 11W 9W - 10W 900-1100 75W 15W >1300 100W 20W Our LED lamps have low energy consumption with a large amount of light compared to incandescent or compact fluorescent lamps. Environmental information about LED bulb - E27 - 470 lm - globe - matt Why an LED lamp? An LED lamp is more expensive than an incandescent bulb, but consumes much less power and lasts many times longer. Lifespan incandescent bulb: 1,000 hours Lifespan LED lamp: 30,000 hours An LED lamp is about 10x more expensive than an incandescent bulb, but lasts 30x longer and consumes 6 to 7 times less power! Count your blessings... And you won't have to replace that lamp every time...
