Q:What are the characteristics of LED bulb?

LED bulb advantages: energy saving: the same brightness, power consumption for ordinary energy-saving lamps 1/4. Environmental protection: no harmful substances such as mercury, no pollution to the environment. (experts point out that mercury contained in a fluorescent energy-saving lamp can contaminate 180 tons of water sources). Economy: as a result of electricity saving, electricity costs can be reduced, and the cost of the lamps can be recovered for one and a half years. A family can save tens of thousands of yuan a month. Low carbon: saving electricity is equivalent to reducing carbon emissions. Long life: LED lamp life of 50 thousand hours, six hours a day, that is, 20 years of life. The price depends on how many watts you need, and the price varies with the wattage. Now the family uses "lightning man" led, very good, the price, quality, those are good, you can go and see.
