Approximately how much power is needed to operate an SPD-Smart product?
SPD-Smart products are extremely energy efficient. At line voltage, SPD film typically uses a maximum of approximately 0.06 watts of power per square foot (0.65 watts/m2). No power is used when the film is in its dark state. When operating at light transmission levels in between the clear and dark states, power requirements are correspondingly lower than the maximum. Exact power consumption depends in part upon the thickness of the SPD film used for a specific end-product application and other factors.
