The Intralux 5100 is a 150-W halogen light source compatible with all Volpi fiber optic components. With a metal housing, ergonomic design and small footprint, it is ideal for industrial and scientific applications. The quick bulb replacement capability, superior illumination intensity and long lamp life reduce downtime. Average lamp life is 3600 hours at 75-percent intensity, and eight intensity steps are available. Once the electrical intensity is selected, fine tlight intensity can be fine-tuned with a patented crescent-shaped diaphragm that maintains constant color temperature. In addition, the unit has a low-noise, vibration-free fan and provides a filter insert holder for the interchange of blue, green, yellow and daylight filters. Using an EKE halogen reflector lamp, the color temperature at 100 percent intensity is 3433 K. The electrical intensity is adjustable from 75 to 110 percent.
