EL panels need a power source providing alternating current (AC). The high efficiency of EL allows useful light to be produced even with line current (100v, 60 Hz in the US at a reduced brightness).
Standard Inverters are available for all shapes and sizes that Technolight has; simply match the inverter to the total amount of square inches of EL panels you are planning to light.
Power use for an EL panel is very low and is generally limited by the efficiency of the inverter circuit. Thus Technolight has optimized the efficiency for the lamp system by optimizing the inverter.
