🔧 Product Description

The Dolan-Jenner MI-LED-US-B1 is the LED evolution of the legendary MI-150 fiber optic illuminator — delivering higher light output than the 150W halogen it replaces, while consuming significantly less energy and requiring virtually zero maintenance. Its high-power white LEDs operate at a consistent 5,000K color temperature with excellent uniformity, making it ideal for color-critical microscopy, inspection, and imaging applications. The long-life LEDs are rated for over 40,000 hours — compared to approximately 200 hours for a 150W halogen — dramatically reducing downtime and eliminating replacement bulb costs. The B1 nosepiece adapter (15mm) makes it a direct drop-in replacement for existing Dolan-Jenner MI-150 and 180 series fiber optic light guide configurations. The stackable housing, small footprint, and universal 100–240 VAC power supply make it equally at home in any lab or production environment worldwide. RoHS compliant, CE certified, and backed by a 2-year warranty. Made in the USA.
