Full Matrix

Full Matrix, Pulse Width Modulation
At the heart of the Stalker SAM-R is Precision Solar Control’s LED Lamp Matrix and LED Pulse Width Modulation. The LED Lamp Matrix concentrates and focuses the LEDs’ light, allowing the motorist to see the sign at a greater distance and, thus, act on the speed warning quicker.

LED Pulse Width Modulation significantly increases the time between battery charges and powers the LEDs so that they remain at a consistent brightness throughout the battery‘s discharge cycle.
