TCP QHB4UZDA650KBLS1D 330W 4' LED Linear High Bay 5000K

TCP 4-Foot LED High Bay with Emergency Battery Backup and Motion Sensor

The TCP QHB4UZDA650KBLS1D is a 330W LED linear high bay from TCP, built for large commercial and industrial ceilings. It suits warehouses, distribution centres, and manufacturing facilities. Key features include an integrated emergency battery backup for power outages and a built-in PIR (passive infrared) motion sensor.

Key Features and Benefits of This LED High Bay

The integrated battery backup keeps emergency egress paths lit during a power interruption, supporting life-safety code requirements in many facilities. The PIR occupancy sensor dims or shuts off the fixture in unused aisles to cut energy costs, while 5000K daylight-white light supports clear visibility for warehouse tasks.

Where to Use the QHB4UZDA650KBLS1D LED High Bay

This high bay suits large warehouses, distribution centres, and industrial plants with high ceilings and code requirements for emergency lighting. The motion sensor works best in zones with variable foot traffic. It is not designed for residential, damp, or low-ceiling retail applications.

Installation and Compatibility Checks

Confirm your facility's emergency lighting code requirements before relying on the integrated battery for egress compliance, since local rules vary. Verify supply voltage, mounting hardware (chain, hook, or surface), and hanging clearance for a 4-foot fixture, and check that ceiling height suits this high-output model.

Additional Buying Context

Choosing a high bay with built-in battery backup avoids installing a separate emergency lighting fixture, simplifying code compliance in larger facilities. Ask Lumenco about the manufacturer warranty and confirm the battery's periodic testing requirements. This model suits facilities upgrading from older fluorescent or metal halide high bays.
