GGJIA Lighting designs, builds, and ships UL- and DLC-certified high bay lights, parking lot fixtures, loading dock lights, and construction work lights — serving facility managers, electrical contractors, and project owners across the U.S. and Canada. Direct from our 80,000 sq ft production facility with U.S. fulfillment from Spokane, Washington. All products carry a 5-year warranty and are tested to UL, ETL, DLC, FCC, and RoHS standards.
LED UFO and Linear high bay lights for warehouses, factories, and gymnasiums. 100W–400W with selectable wattage and CCT. UL Listed, DLC qualified, IP65 rated.
Parking lot fixtures (arm mount / slip fitter / dusk-to-dawn), wall packs 30W–120W, canopy lights, bollard and pathway lights. IP65–IP66 rated.
Temporary LED string lights, tripod work lights, portable hanging work lights. OSHA-compliant with linkable multi-light configurations.
Explosion-proof fixtures for Class I/II hazardous locations; vapor-tight LEDs for cold storage, car washes, food processing; 480V high-voltage variants.
Every GGJIA commercial fixture is independently tested and certified by a Nationally Recognized Testing Laboratory before it ships. Every unit is individually powered on, tested for output, and inspected before packaging.
Our in-house engineering team — not a contracted ODM — controls optical design, thermal management, and driver selection on every fixture. Field issues are diagnosed by the same engineers who built it.
We test components before assembly, not just finished units. This catches LED-binning variation, driver tolerance issues, and housing defects before they reach a customer's site.
Direct production control lets us hold inventory on best-selling SKUs at our U.S. fulfillment point. Most orders ship within 1 business day; standard delivery is 2–7 days across the continental U.S.
Every commercial fixture is covered from the purchase date. If a fixture fails due to driver, housing, or LED chip defect, GGJIA ships a replacement at no charge with prepaid return shipping inside the continental U.S.
For projects of 10+ fixtures, our team produces a free DIALux or AGi32 photometric simulation with fixture count, placement, average footcandle, and uniformity-ratio calculations. Submit to support@ggjia-led.com; turnaround typically 2 business days.
Bulk pricing above 10 units. Project pricing for larger jobs quoted directly. OEM and ODM relationships — including private labeling and custom fixture engineering — are available. Contact sales@ggjia-led.com.
Send us an email, and we'll get back to you within 48 hours.

Footcandle (fc) is a unit of illuminance that measures the amount of light reaching a surface. Use the following guidelines to determine appropriate lighting levels for common commercial and industrial spaces.
| Application | Recommended Illuminance |
|---|---|
| Warehouse Storage (Low Pick Rate) | 10 fc |
| Warehouse Storage (High Pick Rate / Picking Aisles) | 20–30 fc |
Tip: Higher footcandle levels improve visibility, picking accuracy, and worker safety in active storage areas.
| Application | Recommended Illuminance |
|---|---|
| General Assembly | 30 fc |
| Fine Assembly / Inspection | 50–100 fc |
Tip: Precision tasks such as quality control and detailed assembly require significantly higher light levels to reduce eye strain and improve accuracy.
| Application | Recommended Illuminance |
|---|---|
| Auto Repair Shops & Garages | 50 fc |
Tip: Adequate lighting helps technicians identify defects, perform repairs safely, and improve overall productivity.
| Application | Recommended Illuminance |
|---|---|
| Gymnasium (Recreational Use) | 30 fc |
| Gymnasium (Competition Use) | 50–75 fc |
Tip: Competitive sports generally require higher illumination levels for player visibility, spectator experience, and potential video recording.
| Application | Recommended Illuminance |
|---|---|
| Parking Lot (Open Lot, Basic Security) | 1–2 fc |
| Parking Lot (Commercial / Retail) | 2–5 fc |
Tip: Commercial parking areas often use higher light levels to enhance customer safety, security, and wayfinding.
| Application | Recommended Illuminance |
|---|---|
| Loading Docks | 20–30 fc |
Tip: Proper dock lighting improves visibility during loading and unloading operations, reducing accidents and handling errors.
| Space Type | Target Footcandles |
