Quick Answer
The JY-004 is a 200W UFO high bay light for buyers comparing high bay LED shop lights with an adjustable bracket rather than a fixed pendant. Its confirmed data includes 20000 lm output, 100 lm/W efficacy, IP65 protection, a 120-degree beam, a 300 x 85 mm body and 180-degree adjustment. Final LED warehouse lighting spacing and aiming should be checked with project dimensions and photometric data.
JY-004 Key Product Facts
- 200W rated power with 20000 lm output
- 100 lm/W stated luminous efficacy
- 180-degree adjustable mounting bracket
- IP65 cast-aluminum housing
- PC translucent lens with a 120-degree beam
What Is High-Bay Lighting?
The Illuminating Engineering Society defines high-bay lighting as interior lighting where the roof trusses or ceiling are more than approximately 6.1 meters (20 feet) above the floor. That definition describes the space, not the correct wattage for every project. A buyer still needs mounting height, target illuminance, spacing and photometric distribution before approving a layout. Source: Illuminating Engineering Society.
Where Does JY-004 Fit?
JY-004 is intended for high bay LED shop lights, LED warehouse lighting, gymnasiums, supermarkets, basements and garages where bracket aiming flexibility is useful. A practical procurement decision starts with the task area and ceiling geometry, then checks the fixture configuration against structural, electrical and optical requirements.

How Should a Buyer Evaluate This Model?
| Decision Point | Recommended Check |
|---|---|
| Aiming angle | Set the bracket only after the mounting position and target area are known. |
| Structural support | Confirm the wall or ceiling point and fasteners for the final fixture load. |
| Light distribution | Use the 120-degree beam together with mounting height and spacing in the lighting calculation. |
| Environment | Check whether dust, moisture, ambient temperature or cleaning conditions affect the installation. |
The U.S. Department of Energy advises commercial and industrial lighting buyers to compare like products, review manufacturer performance data and photometric information, and avoid over-lighting a space. These principles are useful for any B2B high-bay quotation, even when local codes and project targets differ. Source: U.S. Department of Energy FEMP.
What Must Be Confirmed Before Ordering?
- Input voltage, driver brand, power factor, surge protection and dimming option
- Color temperature, CRI and the photometric file for the exact configuration
- Fixture weight, bracket hardware and rated capacity of the mounting surface
- Certificates, warranty, ambient-temperature limits, quantity and lead time
IP ratings are classified under IEC 60529, the international standard for degrees of protection provided by enclosures. The product materials state IP65, but buyers should request the applicable test or certification documentation when a tender requires formal evidence. Source: IEC 60529.
Recommended RFQ Information
Send the project country, supply voltage, ceiling or mounting height, target area, required illuminance, operating hours, quantity, control needs and any certification requirements. For a warehouse, include aisle dimensions and rack height. For a workshop or factory, identify task areas and any dust, moisture or temperature constraints.
FAQ
Can JY-004 be aimed after installation?
The supplied bracket graphic shows adjustment through 180 degrees. Set and lock the final angle according to the approved mounting and lighting plan.
Is JY-004 an IP65 high bay light?
Yes. IP65 is stated in the product materials. Request formal test documentation if the project specification requires it.
Is 200W suitable for every warehouse?
No. The correct quantity and spacing depend on mounting height, target illuminance, area geometry and optical distribution, not wattage alone.
