TCP QHB4UZDA450KB 220W 4' LED Linear High Bay 5000K

TCP 4-Foot LED High Bay with Integrated Emergency Battery Backup

The TCP QHB4UZDA450KB is a 220W LED linear high bay from TCP, built for large commercial and industrial ceilings. It suits warehouses, distribution centres, and manufacturing floors. Key features include an integrated emergency battery backup and 5000K daylight-white light output for clear task visibility.

Key Features and Benefits of This LED High Bay

The built-in battery backup lights the fixture during a power outage, helping facilities meet emergency lighting needs without installing a separate unit. Dimmable operation allows pairing with lighting controls for energy savings, and the 50,000-hour rated life reduces maintenance on hard-to-reach high-ceiling mounts.

Where to Use the QHB4UZDA450KB LED High Bay

This high bay suits large warehouses, distribution centres, and manufacturing areas with high ceilings, particularly facilities where emergency lighting code compliance is required. It works best across wide aisles and open floor plans. It is not intended for low-ceiling retail, residential, or damp outdoor applications.

Installation and Compatibility Checks

Confirm your facility's emergency lighting code requirements before relying on the built-in battery for compliance, since rules vary by jurisdiction. Verify supply voltage, mounting hardware (chain, hook, or surface) rated for a 4-foot fixture, and hanging clearance before installation.

Additional Buying Context

This model suits facilities upgrading from older high bays lacking integrated backup lighting, simplifying code compliance without a separate emergency fixture. Ask Lumenco about manufacturer warranty terms and periodic battery testing requirements, and confirm dimming compatibility if pairing with an existing lighting control system.
