The C-100PA is a high-intensity ultraviolet lamp with a lamp head measuring 7 by 9.5 inches, allowing it to be used for the detection of cracks, defects, contamination and surface flaws in confined places that are inaccessible to larger lamps. The lamp has a 100-watt, mercury vapor spot bulb with a nominal steady-state long-wave UV-A (365 nanometer) intensity of 5,000 microwatts per centimeter squared (µW/cm²) at 15 inches. The lamp’s visible light emission is less than two foot-candles (0.2 lux), and it easily meets MIL and ASTM specs for FPI and MPI. The bulb has an average rated life of 5,000 hours.
