The Spectroline FC-150 ultrahigh-intensity UV inspection lamp from Spectronics has a built-in fan that reduces operating temperatures and prevents the lamp from becoming too hot to handle. The lamp delivers a nominal steady-state UV-A (365 nm) intensity of 4500 µW/cm² at 38 cm. It reveals even the smallest cracks and defects, ensuring accurate inspections. The unit meets MIL and ASTM specifications for fluorescent particle inspection and magnetic particle inspection. It has a lightweight head and a contoured pistol-grip handle that is located at the balance point of the lamp, so it can be held comfortably for long inspection periods. A Built-In-Ballast bulb produces the power of a transformer-based lamp without a heavy external transformer. The 150-W bulb has an average rated life of 5000 h.
