LED Linear High Bay Light – Selectable Wattage & CCT, Optional Uplight

Product Description

The LONYUNG LED Linear High Bay Light is designed for indoor projects that require high light output and flexible configuration. Each model offers three selectable wattage settings and a choice of 4000K, 5000K, or 5700K, allowing output and color temperature to be matched to the installation.

For spaces that need additional ceiling illumination, an optional 30% uplight configuration combines direct downlighting with indirect lighting reflected from overhead surfaces. This helps reduce the dark-ceiling appearance of downlight-only installations. The effect depends on ceiling reflectance, suspension clearance, and fixture placement.The series includes four models with listed typical lumen outputs from 16,000 to 64,000 lumens and efficacy up to 160 lm/W. Standard 0-10V dimming supports adjustment through compatible controls. A plug-and-play sensor and emergency battery backup are available as optional configurations.

Product Advantages

● Selectable Wattage for Flexible Project Planning

Each model provides three wattage settings, allowing installers to select the output appropriate for the space. This supports projects with different lighting needs across storage areas, production zones, and open commercial interiors.

● Three Color Temperatures in One Fixture

The selectable 4000K, 5000K, and 5700K settings provide flexibility when specifying the appearance of the lighting. A single model can accommodate different project preferences without requiring a separate fixed-CCT version for each selection.

● Optional Direct and Indirect Lighting

The optional uplight configuration adds light toward the ceiling while maintaining downward illumination. It can help create a brighter overhead appearance in spaces with suitable ceiling surfaces and suspension clearance.

● Dimming and Optional Sensor Integration

Standard 0-10V dimming enables output adjustment through compatible controls. The optional plug-and-play sensor provides an additional control choice for projects that require occupancy-based operation, subject to the required sensor specifications.

● Output Options Across Four Models

The series covers a range of fixture sizes and lumen outputs. Selection can be based on mounting height, target illuminance, room dimensions, and the proposed fixture layout.

● Suspension Mounting Kit Included

The supplied mounting kit supports suspended installation. For uplight configurations, the suspension arrangement should provide suitable clearance between the fixture and the ceiling.

● Warehouses and storage facilities

● Manufacturing plants and production areas

● Gymnasiums and indoor recreation facilities

● Convention and exhibition centers

● Grocery stores and large retail spaces

● Other high-ceiling indoor commercial facilities

FAQs

1. What is the benefit of the uplight option?

The uplight option directs light toward the ceiling, adding overhead brightness alongside the fixture’s downward illumination. Its effectiveness depends on ceiling color, reflectance, mounting clearance, and the lighting layout.

2. Is uplight included as standard?

No. The 30% uplight configuration is optional. Include your uplight requirement when requesting a quotation so the appropriate configuration can be confirmed.

3 Which wattage settings are available?

The four models offer 100W / 80W / 65W; 160W / 150W / 130W; 255W / 200W / 170W; and 400W / 320W / 270W. Each model supports its own three settings.

4. Can I select the color temperature?

Yes. The series offers standard selectable 4000K, 5000K, and 5700K color temperatures. For other color temperature options, please contact our sales team for customization.

5. Does this linear high bay support dimming?

Yes. Standard 0-10V dimming allows output adjustment using compatible controls. Confirm dimmer compatibility for the  fixture and installation.

6. Are sensors and emergency battery backup available?

Yes. A plug-and-play sensor and emergency battery backup are optional. Specify your requirements when ordering and confirm sensor functions, emergency output, backup duration, and model compatibility.
