At this current level the device will function at its best giving you the right color and light intensity. LEDs are current driven devices and must be operated with constant and limited current. The forward voltage drop when the device is operated at the specified forward current is stated in typical and maximum values. For higher operating voltages one must incorporate current limiting resistors. The practically maximum voltages one can operate LEDs is 49 volts.
Higher voltages require large high wattage resistors.
In both cases current limiting resistors must still be used. Foot Lampert units are used when the device has large reflective and diffusing lenses and reflectors and a central light spot cannot be located. We invite your calls and questions on how to design and select the best Lumex-Lite for your product. Custom designs are also invited without any up-front cost to you.
