The lighting efficiency of LED lighting has increased by about 50% (picture from the US Energy Information Administration)
LED lighting in 2012 just exceeded 60lm/W, and in 2014 this value jumped to 100lm/W, not only incandescent, but also has great advantages compared with energy-saving lamps. LED luminaires not only improve light efficiency, but also expand the product range, allowing consumers to choose more types of energy-saving lighting products.

In addition, according to EIA's long-term survey, even if there is no energy-saving subsidy, the price of LED lighting products has a “significant continuous declineâ€, which is also good news for consumers.

"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500℃) is lower than the combustion temperature of traditional cigarettes (600-900℃), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."
Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale.
They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 ° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 ° C.
Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.
Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
