The IOTA ILB CP18 HE CW is a UL Listed constant power LED emergency driver that enables a single LED fixture to perform seamlessly in both normal and emergency operating modes. During standard operation, the connected fixture functions as usual under the power of the primary LED driver. In the event of an AC power failure, the ILB CP18 HE CW automatically transfers power from the normal driver to its integrated emergency system, operating the LED load for a full 90 minutes. This consistent runtime ensures uninterrupted illumination during critical egress or safety conditions. The unit incorporates a charger and converter circuit within a compact, low-profile galvanized steel housing and connects to a separate, maintenance-free sealed lead acid battery pack.
Delivering a constant output of 18 watts at a nominal range of 20–58 VDC, the ILB CP18 HE CW maintains full light output throughout the entire emergency duration with no degradation in brightness. Its auto-sensing Class 2 output automatically adjusts within the 20–58 VDC range to accommodate a wide variety of LED designs, making it compatible with many Class 2 fixtures. This constant wattage performance ensures reliable lumen delivery even as battery voltage decreases over time. The system’s lumen performance remains stable from minute one to minute ninety, sustaining output levels equivalent to 100–130 lm/W efficacy, depending on the connected fixture’s design—resulting in consistent light levels of approximately 1800 to 2340 lumens during the entire emergency period.
The ILB CP18 HE CW is built for durability and versatility, supporting an extended ambient temperature range from -20°C to 60°C. This wide thermal tolerance makes it particularly suitable for outdoor pathways, cold storage areas, and other freezing or high-temperature environments where reliable egress lighting is essential. Its sealed lead acid battery is designed for high temperature resilience and long operational life, requiring 24 hours for full recharge after a discharge cycle.
Every component is enclosed in a robust galvanized steel housing, compliant with UL 1310 and Output Class 2 standards. The assembly includes an IP67-rated single-piece test switch and charge indicator kit for easy visual status checks and manual life-safety testing. The ILB CP18 HE CW can be installed with either switched or unswitched fixtures and is suitable for damp locations as well as IP67-rated enclosed and gasketed luminaires.
Certified under cUL and compliant with NFPA 101, NEC, IBC, and Life Safety Code emergency lighting standards, this emergency driver ensures code-compliant performance in commercial and industrial environments. It operates on universal input voltage from 120 to 277 VAC at 50/60 Hz, meeting a broad range of installation requirements. Fully RoHS compliant and backed by a three-year warranty, the IOTA ILB CP18 HE CW combines constant power reliability, wide environmental compatibility, and long-term dependability for critical life-safety lighting applications.
