The MAXIMA ML-3500 Series ultraviolet lamps use advanced Micro Discharge Light (MDL) technology, plus a unique filter and bulb/reflector, to deliver up to 10 times the UV-A (365nm) output of conventional HID inspection lamps. The ML-3500S model features a spot reflector and has a nominal steady-state UV-A intensity of 50,000 µWcm2 at 15 inches (38cm). The ML-3500FL features a flood reflector that delivers a nominal steady-state intensity of 4,500 µW/cm2 at 15 inches. All bulbs feature a rated life of 2,000 hours. The lamps produce virtually zero emission of hazardous UV-B and emit minimum visible light.
