  product introduction  

parameter index of high quality energy saving lamp
1. electrical parameters
(1) voltage range: rated voltage + 10% -20%
(2) power range: rated (nominal) power + 5% -10%
(3) power factor: select pf>0.6 and pf>0.9 according to the actual situation
(4) comply with safety regulations and electromagnetic interference and emc electron magnetic compatibility emc regulations
(5) electronic ballast working frequency avoids the remote control frequency of household appliances
(6) meet the requirements of stable and reliable work in high temperature environment and low temperature environment
   
2. optical parameters
(1) luminous flux: the sum of the amount of light emitted by the light source per second: used to indicate the amount of light emitted by the lamp tube, that is, the amount of light emitted. the universal symbol ф indicates that the unit is lm. luminous efficiency and luminous flux requirements: less than 15w, luminous efficiency requirements ≥ 45lm/w; greater than or equal to 15w, luminous efficiency requirements ≥ 60lm/w.
(2) color rendering index: ≥ 80
(3) color temperature: small color temperature deviation and good consistency
(4) start time: less than or equal to 1 second
3. life parameters
(1) actual life for more than eight thousand hours (the luminous maintenance rate reaches more than 70%)
(2) it can work stably and reliably in the effective life cycle, high temperature 85℃ environment and low temperature-20℃ environment; and withstand the impact of voltage fluctuation under the above temperature conditions, energy-saving lamps can work stably and reliably

4. mechanical parameters
(1) the connection strength between the lamp tube and electronic ballast meets the specified torque requirements
(2) the connection between lamp holder and shell meets the specified torque requirements
