JLM DHID uses microprocessors to control and regulate a HID lamp. The firmware provides control algorithms to supply varying lamp currents during start-up and during lamp operation. The firmware controls the initial voltage strike to the bulb to start it and then controls current in the bulb for the most efficient operation of the lamp.
JLM DHID' benefit are: save energy and maintenance costs over magnetic ballast HID lamps; automatic loss-of-lumen compensation as the lamp ages (reduced tube darkening); produces up to 40% more lumens per watt than magnetic ballasts; increased life expectancy of the lamp compared to magnetic ballast; DHID ballast generates less heat, reducing air conditioning energy cost; 50% to 70% dimming of incoming power produces additional cost savings, with automatically controlled lamp dimming in unoccupied areas.
