Solar Powered DC Off Grid Lighting Rentals

DC input LED flood lights are directional lighting luminaires that operate on direct current (DC) power at a forward directional voltage, such as 12 VDC, 24 VDC, or 48 VDC. These products are designed to be connected to a DC power source provided by solar photovoltaic systems, marine vessels, mobile diesel generators, vehicles, and other types of DC power systems. 

 Conventionally, floodlighting had been delivered by high-intensity  discharge (HID) sources such as metal halide or high pressure sodium  (HPS) lamps. To operate these alternating current (AC) powered light  sources on a solar powered lighting system or a low-voltage DC grid, an  inverter is required to transform the DC power into a utility frequency  alternating current that can be fed into the HID lamps. The use of a  DC-to-AC power converter incurs power losses, which adds to the inefficiency of HID flood lights. 

 Without the burden of regulating an AC input that often has a variety of  voltage and current contaminations on the pure sinusoidal waveform, DC  powered LED flood lights have the fundamental advantages of higher  circuit efficiency, system reliability, and cost competitiveness when  compared to the AC powered counterparts. This is due to the reduced  complexity of the driver circuitry. Creating a regulated LED load from a  DC power source can go from a very simple concept, using a passive  polarization resistor, to a more sophisticated solution using active  current regulator circuits.
