TCP QHB2UZDA450KB 220W 2' LED Linear High Bay 5000K
Key Features and Benefits of This LED High Bay
The built-in emergency battery backup keeps the fixture lit during a power outage, helping facilities meet emergency lighting needs without a separate unit. Dimmable operation supports lighting controls for energy savings, and 5000K output gives bright, daylight-like visibility for detailed warehouse and production tasks.
Where to Use the QHB2UZDA450KB LED High Bay
This high bay suits warehouses, distribution centres, gyms, and manufacturing areas with ceilings roughly 15 to 25 feet high, especially where emergency lighting code compliance is required. Its 5000K output works well for detail-oriented tasks. It is not intended for low-ceiling retail, residential, or damp outdoor use.
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), and hanging clearance suit your ceiling height before installation.
Additional Buying Context
This model suits facilities upgrading from older high bays that lack 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 control compatibility if pairing with an existing lighting system.

TCP QHB2UZDA340KLS1D 165W 2' LED Linear High Bay 4000K
Key Features and Benefits of This LED High Bay
0-10V dimming lets the fixture pair with lighting controls to cut energy use during low-occupancy hours. A CRI (colour rendering index) of 80 keeps colours accurate for warehouse tasks, while the 50,000-hour rated life reduces bulb changes on hard-to-reach high-ceiling mounts, lowering long-term maintenance costs.
Where to Use the QHB2UZDA340KLS1D LED High Bay
This high bay suits warehouses, distribution centres, gyms, and manufacturing areas with ceilings roughly 15 to 25 feet high. The PIR sensor works best in aisles or zones with intermittent foot traffic. It is not intended for low-ceiling retail, residential, or damp outdoor locations.
Installation and Compatibility Checks
The fixture accepts 120-277V input, covering most commercial electrical services, but an electrician should confirm panel voltage before ordering. Check that any existing 0-10V dimming control is compatible, and verify mounting hardware (hook, chain, or surface) and hanging clearance suit your ceiling height and layout.
Additional Buying Context
This high bay is a practical upgrade for facilities replacing older fluorescent or metal halide fixtures, offering lower running wattage for similar light levels. Ask Lumenco about manufacturer warranty terms before purchase, and consider matching CCT (colour temperature) across a facility so lighting looks consistent throughout the space.
