McPhilben Emergency Lighting Brand
A titan of the 20th-century safety industry, McPhilben Emergency Lighting earned its reputation by blending rugged thermoplastic durability with the cutting-edge Xtest self-diagnostic technology. While the brand has since been woven into the history of lighting giants like Genlyte and Signify, its precision-engineered exit signs and emergency units remain a gold standard for commercial reliability. These sleek, “eyeball-style” lamp heads did more than just meet UL 924 standards—they provided a sophisticated, microprocessor-driven peace of mind for retail and industrial spaces alike. Although the original line is discontinued, the spirit of McPhilben’s innovation lives on through its high-performance legacy parts and the modern Chloride systems that replaced them.

Customer Experiences
Arthur Sterling I have been managing a large retail warehouse for over two decades, and our original McPhilben CAX6 units are still holding strong thanks to the Xtest self-diagnostic circuitry. The semi-recessed heads look much cleaner than the bulky “bug-eye” lights you see elsewhere, and even though the brand has transitioned to Chloride, I’ve had no trouble sourcing the 6V replacement batteries to keep our building up to code.
Elena Rodriguez As an electrical contractor, I always recommended McPhilben for commercial retrofits because their 120/277VAC compatibility made installation across different power grids incredibly simple. I recently serviced a ten-year-old installation at a local school district, and the vandal shields we added back then have kept the units looking brand new despite being in a high-traffic hallway.
Marcus Thorne During a major brownout last summer, our McPhilben emergency exit signs were the only things that stayed bright throughout the entire 90-minute discharge period. The brownout protection feature is a lifesaver for our industrial plant where power fluctuations are common, and the peace of mind knowing the units perform monthly self-tests automatically is worth every penny.
McPhilben FAQ
What should I do if my McPhilben emergency light fails its monthly test?
If the unit does not illuminate for the full 30 seconds during a manual test, or if the Xtest visual indicator shows a fault code, the battery is likely the culprit. Most McPhilben units utilize lead-calcium or Ni-Cad batteries that require replacement every 3 to 5 years; check the internal battery date and replace it with a compatible 6V or 12V model to restore full functionality.
Can I still get replacement parts for discontinued McPhilben models?
Yes, while the brand name has been integrated into Chloride (Signify), many universal parts and specific replacement batteries are still widely available. Common components like the 10.8V Ni-Cad battery packs (part #791741001) or the 6V lead-acid cells (part #789788001) are stocked by specialized emergency lighting distributors and battery retailers.
How does the Xtest self-diagnostic system work?
The Xtest technology is a microprocessor-based system that automatically performs the NFPA-required 30-second monthly and 90-minute annual tests. It monitors the battery voltage, charging circuit, and lamp integrity, providing a visual warning via an LED indicator if any component fails to meet safety standards, which eliminates the need for manual “push-to-test” inspections.
Is it possible to upgrade my old McPhilben exit signs to LED?
While many original McPhilben signs used incandescent or fluorescent lamps, they can often be retrofitted with universal LED kits to save energy and reduce maintenance. However, given that many of these housings are now decades old, it is often more cost-effective to replace the entire unit with a modern Chloride LED exit sign, which will fit similar mounting footprints.
What are the voltage requirements for McPhilben emergency units?
McPhilben products were designed for professional commercial installation and typically feature universal 120/277VAC input capability. This allows them to be installed in standard small-business environments (120V) as well as larger industrial or retail facilities that utilize higher-voltage (277V) lighting circuits.
