Middle Power LEDs are those that usually use less than 0.3 Watt of energy, are fairly small and require minimal or no cooling. Small as they are, they play a key role in the ever larger penetration of LED into the lighting market. This comes from the possibility to build arrays of middle power LEDs that deliver the required light output for a given form factor.
Thus, many of the popular applications of LED technology use modules with middle power LEDs. Among them: fluorescent LED replacements, LED lamps, LED linear modules for cove lighting, linear luminaries, LED panels, back-light modules for illuminated ceilings or signs.
