Description & Specifications
The LM4X 4-inch, air-cooled LEDs provide a significant increase in output power needed in large test facilities
or for fast pressure sensitive paint measurements. Large test sections require more excitation light because
the model is further from the data acquisition system and fast PSP systems require significantly shorter
camera exposure times. The larger heat sink and higher number of individual LEDs allows the system to be
driven harder than the 2-inch, air-cooled LED systems, providing ~5 times the output power. Three parts
comprise the 4-inch, air-cooled LED: the power supply, the LED module and the umbilical power cable.
