Quality：LED lamps typically do not burn out like incandescent bulbs; On the contrary, they gradually darken over time. In addition, they do not emit ultraviolet or infrared rays, generate little heat, are resistant to shock and vibration, can operate effectively in cold environments, and do not contain mercury. LEDs reduce harmful emissions into the environment, including mercury, and eliminate the opportunity for pollution when handling bulbs, which is good news for the environment. It is assumed that the higher the quality of LED lamps, the higher their adoption rate.
Dynamic：energy-saving LED lamps often consume less than one sixth of their incandescent or halogen lamps’ energy consumption, 2-3 times lower than most CFLs. The efficiency of a light bulb can be determined by comparing the amount of light generated with the amount of energy consumed. The goal should be to find a lamp that emits the most light, consumes the least energy, and is priced best for a person’s budget. However, regardless of price, research shows that LED bulbs are the most energy efficient: LED bulbs produce 90 to 112 lumens per watt; Compact fluorescent lamps produce 40 to 70 lumens per watt; Traditional incandescent bulb devices produce only 10 to 17 lumens per watt. Therefore, from a purely scientific perspective, LEDs are the most energy efficient bulbs, because with proper design, the efficiency of LED circuits will approach 80%. This means that 80% of electrical energy is converted into light energy, while the remaining 20% is lost as heat energy. This conversion to light energy can be compared to the conversion of incandescent bulbs, which have a working efficiency of about 20% (80% of electrical energy is lost in the form of thermal energy). In terms of the environment, the reduction in electricity consumption leads to a reduction in greenhouse gas emissions. It is assumed that energy conservation is positively correlated with the willingness to purchase LED lamps. It operates at approximately 20% efficiency (80% of electrical energy is lost in the form of heat). In terms of the environment, the reduction in electricity consumption leads to a reduction in greenhouse gas emissions. It is assumed that energy conservation is positively correlated with the willingness to purchase LED lamps. It operates at approximately 20% efficiency (80% of electrical energy is lost in the form of heat). In terms of the environment, the reduction in electricity consumption leads to a reduction in greenhouse gas emissions. It is assumed that energy conservation is positively correlated with the willingness to purchase LED lamps.
Durability: The service life of an LED lamp depends on the number of operating hours before the LED emits 70% of its initial light output. The top LEDs in well-designed lamps have an expected service life of 30000 to 50000 hours, significantly higher than the 1000 hours of typical incandescent bulbs and 8000 to 10000 hours of similar CFLs. The longer the lifespan of LED lamps, the better the return on their high initial investment by consumers. Therefore, it is assumed that the durability of LED lamps is positively correlated with purchase intention.
