The Photocell is a resistor attached to photosensitive plates. When more lux levels come into contact with these plates, the amount of current that travels through the resistor, known as resistance, changes, resulting in light turning on or off. During daylight, for instance, a 2700k warm white LED bollard will operate at a very low capacity while during the night, it will operate at full capacity. Photocell lighting products also automatically adjust the on/off time of the bollard with the photocell to match the shift of daytime/ night-time throughout the year, taking away the need for the end user to amend it. The bollard with Photocell has a lux level trigger point of 35 lux, so when the sensor detects a light level below 35 lux it will turn the luminaire on, similarly when the bollard with photocell detects a light level above 35 lux it will turn the luminaire off.
