industrial smart-lighting projects should distinguish DALI-2 control certification, D4i luminaire data and Zhaga-D4i socketed interfaces. Improve useful illuminance and reduce glare or dark zones through optics, spacing and aiming control. This article covers site inputs, specific product directions, photometric checks, implementation and acceptance for B2B industrial lighting projects.
DALI-2, D4i and Zhaga-D4i address different layers of interoperability, luminaire data and module interfaces. Projects should verify certified products, addressing, data access, gateways, fallback behavior and commissioning scope.
Define the site conditions first
Confirm dimensions, clear height, mounting positions, obstructions, work-plane height, electrical circuits, operating hours and the existing fixture baseline. Add temperature, moisture, dust, corrosion, cleanroom or hazardous-area requirements where relevant.
Industrial lighting products and search terms
Relevant product directions include Industrial Smart Lighting Control System, Smart-Control LED High Bay Light. These product names help establish a comparison range; final wattage, optics, protection rating and quantity must be checked against the actual site.
LED product names and common procurement queries
These phrases summarize recurring Baidu autocomplete directions in China. They are organized as buyer questions, not exact search-volume claims or brand rankings.
LED High Bay Light
Common queries：LED high bay manufacturer, 100W LED high bay, 150W high bay model, 200W high bay price, high bay mounting height
Use mounting height, target lux, optics, temperature and controls before comparing wattage, model and price.
LED Explosion-Proof Light
Common queries：LED explosion-proof light manufacturer, explosion-proof LED model, hazardous-area LED fixture
Provide zone, gas or dust, temperature class, mounting, cable entry, wattage and optics before selection.
LED Cold Storage Light
Common queries：LED cold storage solution, freezer LED light, cold-room wiring, low-temperature luminaire
Confirm minimum temperature, cold start, condensation, aisle optics, sensing and maintenance safety.
LED Floodlight
Common queries：LED floodlight manufacturer, LED floodlight wiring, industrial floodlight price, LED floodlight driver
Review throw, pole position, optics, aiming, glare, surge protection and bracket loading before wattage.
LED Road Light
Common queries：LED street light manufacturer, LED road light wattage, 100W street light, IP65 road light
Road width, pole height, spacing, optics, uniformity and dimming determine the model.
Illuminance, efficacy and optical distribution
Efficacy indicates electrical efficiency, while optical distribution determines where the light reaches the working plane. Review beam angle, spacing, aiming, reflection and maintenance factor together instead of comparing wattage only.
Construction, protection and controls
Check thermal design, driver, voltage, power factor, surge protection, sealing, cable entry, mounting and service access. Sensor dimming and zoning should also be tested for trigger range, delay, minimum output and failure fallback.
Implementation workflow
- Record the existing illuminance, power, layout and operating baseline.
- Select construction, output, optics and controls from the site conditions.
- Validate a representative pilot area.
- Adjust spacing, aiming or controls before full installation.
- Repeat measurements and archive commissioning records.
Improve useful illuminance and reduce glare or dark zones through optics, spacing and aiming control.
Project Checklist
- Confirm site inputs for optics, glare and uniformity
- Record design assumptions and measurable acceptance criteria
- Check installation, controls and maintenance access
- Archive product data, commissioning results and follow-up actions
Major Chinese standards for project review
Standard status was reviewed against official Chinese platforms on 2026-08-10. Confirm the current edition, implementation date, local requirements and contract scope before use.
GB/T 7000.1-2023Luminaires - Part 1: General Requirements and Tests
Current luminaire safety and test basis, effective from 1 January 2026.
Official recordGB/T 31897.201-2025Luminaire Performance - Particular Requirements for LED Luminaires
Current particular performance requirements for LED luminaires, effective from 1 May 2026.
Official recordGB/T 5700-2023Methods of Measuring Lighting
Lighting measurement methods with project-specific points, instruments, environment and control state.
Official recordGB/T 4208-2017Degrees of Protection Provided by Enclosure (IP Code)
Check dust and water protection; IP does not prove corrosion, low-temperature or explosion protection.
Official recordGB/T 17743-2021Radio Disturbance from Electrical Lighting
Limits and measurement methods for radio disturbance from lighting equipment.
Official recordFrequently asked questions
Can the old fixture be replaced at the same wattage?
Not reliably. Efficacy, optics, mounting height and depreciation differ, so target illuminance and layout should be checked again.
What is needed for a quotation?
Provide the application, area, mounting height, photos, target lux, environment and operating hours.
How should suppliers be compared?
Use the same site assumptions and compare model, power, efficacy, optics, protection, driver, warranty, delivery, installation and control scope.
