Dimmable Logos - What Do They Mean?
Logos used throughout the Interior/Exterior section to help quick referencing of important product features are explained below.
Light intensity is reduced as the DC input voltage is reduced below the lamps specified operating voltage.
Light intensity is controlled through the lamp’s own internal circuitry via in-built buttons, an external DC power source and a standard switch. See specific lamp instructions for further information.
Light intensity is adjusted between 10-100% using a high frequency PWM (pulse width modulation) DC power supply, with adjustable duty cycle control.
Light intensity can be switched between 100% and a lower level factory pre-set value, usually via an additional cable input supplied with the lamp using a positive feed from the DC power supply within the lamps operating voltage range.
