  • 1. The above parameters are subject to room temperature of 23 degrees unless otherwise specified.
    2. The maximum on-current refers to the surge current on the lamp.
    3. When the ambient temperature is 85 degrees, the maximum allowable voltage should be reduced to 72% of the original value.
    4. The current time curve data is measured at the ambient temperature of 85 ° C, and the cross section of the wire is ≥4mm²
