Light sources get their power in three different ways. You'll be able to tell by looking at the ending of the light source's model number.

1. Lights with model numbers ending in "M" or ending with no letter, are powered from the sensor. These hook up to the sensor with QD cables.



2. Lights with model numbers ending in "N" are powered by a dedicated external power supply. These lights hook up to the power supply with a nine-pin QD.



3. Lights with model numbers ending in "W" are powered by 24V DC power supply. These lights hook up to the power supply with flying leads.
