what is the difference between working lifetime,working time,lifespan
|
|
I search for products in Alibaba, i found something i didn't quite understand,like"working time(hours), working lifetime(hour),lifespan(hour)",
i found the parameters filled in by the merchant are the same,but i know ,there are different things,who can tell me the difference.

working lifetime means:the duration of sb/st life,working lifetime(hour) means: working time+Unused time. for lights ight on time+Light off time
lifespan: like working lifetime,Whether you use it or not
working time:Accumulated working hours,If the light attenuation is too large,must be changed |
