3.2 Environmental Absolute Maximum Ratings Storage Item MIN. MAX. Ambient Temperature -20 C 70 C Humidity Note 4
Operating MIN. MAX. 0C 50 C Note 4
Remark Note1,2,3 No Condensation
Note 1. Ta at -20 C --------< 48hours, at 70 C --------< 120 hours. Note 2. Background color changes slightly depending on ambient temperature. This phenomenon is reversible. Note 3. When LCM is operated at 0 C, the lifetime of the CFL will be reduced. The response time at 0 C will increase.
Note 4. Ta<=50 C : 85%RH MAX. Ta> 50 C : Absolute humidity must be lower than the humidity of 85% RH at 50 C.
