However, for additional protection against transients, it is recommended to use separate overvoltage protection components, which can be found on the manufacturer’s website. The luminaire is equipped with an LED module with a connected wattage of 7.8 W and a luminaire connected wattage of 9.2 W. The rated temperature for the luminaire is between 25°C and 35°C. The ambient temperature should also be within this range for optimal performance. The LED module has a module designation of LED-1021/930 with a color temperature of 3000 K. It has a color rendering index (CRI) greater than 90, indicating high color accuracy. The module has a luminous flux of 1180 lm, while the luminaire has a luminous flux of 562 lm. The luminaire has a luminous efficiency of 61.1 lm/W. Product Usage Instructions:

Ensure that the luminaire housing and external LED power supply unit are not covered by any heat insulating materials during installation.
Handle the LED module with care and avoid touching the light output opening directly during installation or relamping.
If you need to replace the LED module, refer to the label inside the luminaire to identify the module designation.
