Tokyo Electric Power "TEPCO Life Lab" announced the results of investigations and analysis on the cognitive status and replacement of energy-saving light bulbs (bulb-type fluorescent lamps and LED bulbs). The results show that the initial cost of replacing fluorescent lamps and LED bulbs with incandescent lamps has been controlled to a level acceptable to consumers.
The survey was conducted on the Internet by a population of 1,450 (725 males and 725 females) aged 20 to 70 in Japan. For the replacement of incandescent lamps into long-life, low-power bulb-type fluorescent lamps and LED bulbs, the problem of acceptable cost recovery, the actual cost recovery time of 90% of respondents who choose to redeem for bulb-type fluorescent lamps will exceed 5 Months. When redeeming for an LED bulb, the actual cost recovery time will exceed 60% of the answer for 60%. In other words, the spread has been controlled to a range acceptable to consumers.
Consumers are more aware of LED bulbs. Regarding the power consumption ratio of LED bulbs to incandescent lamps, almost half of the respondents know the actual power consumption ratio. The ratio of the power consumption of the bulb-type fluorescent lamp to the incandescent lamp is only over 20%. In terms of energy-saving lamp life, it is known that the life of a bulb-type fluorescent lamp is less than 20%, and the LED bulb is only 30%.
Regarding the replacement situation, about 60% of the respondents answered that some or all of the incandescent lamps have been replaced with bulb-type fluorescent lamps. About 30% of the respondents replaced the incandescent lamp before it reached the end of its life. The main reasons for the replacement include "light power consumption (80%)" and "long life (more than 70%)". The ratio of replacement to LED bulbs is only 5%. The reason for the replacement is the same as that of the bulb type fluorescent lamp, but there is more dissatisfaction with the higher price. However, if "depending on the conditions" is included, about 90% of the respondents answered that they hope to use LED bulbs in their homes in the future. Therefore, Tokyo Electric Power Analysis believes that if the price of LED bulbs continues to decline, it is likely to accelerate. The popularity of LED bulbs.
