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.

● Selectable wattage: Three power settings per model to suit different lighting requirements.
● Three color temperature selectable: 4000K, 5000K, or 5700K.
● Optional 30% uplight: Adds illumination above the fixture for projects requiring ceiling brightness.
● Efficacy up to 160 lm/W: High light output relative to power consumption.
● 0-10V dimming: Adjust output using compatible dimming controls.
● Four model sizes: Listed typical lumen outputs of 16,000, 25,600, 40,800, and 64,000 lumens.
● Suspension kit included: Supplied for suspended installation.
● Optional accessories: Plug-and-play sensor and emergency battery backup available.
● Long-term operation: L70 lumen maintenance exceeding 50,000 hours and a 5-year warranty.
● Suitable for customized industrial lighting projects
● 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

Step 1:Open the accessory package, take out the accessories as shown in Figure 1.
Step 2:Install the fixture with v-hooks and chains. (As shown in Figure 2)
Step 3:Remove the wiring back plate and take out the terminal connector and dimming wires. (As shown in Figure 3)
Step 4:Feed the wiring back plate through the flexible conduit (not provided).
Step 5:Make wiring. (As shown in Figure4)
Step 6:Make sure all the wires are tightly connected, then lock the wiring back plate onto the fixture. (As shown in Figure 5)
Step 7:Select your required watt and CCT before turn on the power.

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.
No. The 30% uplight configuration is optional. Include your uplight requirement when requesting a quotation so the appropriate configuration can be confirmed.
The four models offer 100W / 80W / 65W; 160W / 150W / 130W; 255W / 200W / 170W; and 400W / 320W / 270W. Each model supports its own three settings.
Yes. The series offers standard selectable 4000K, 5000K, and 5700K color temperatures. For other color temperature options, please contact our sales team for customization.
Yes. Standard 0-10V dimming allows output adjustment using compatible controls. Confirm dimmer compatibility for the fixture and installation.
