Frequently Asked Questions

How long does the full 8-step process take?+
Typically 35-50 days from Step 01 to delivery: 1-2 days for requirements + DIALux, 1-2 days for product selection, 15-30 days production, 20-35 days sea freight to Middle East. Air freight available for urgent orders.
Is the DIALux simulation really free?+
Yes. We provide DIALux photometric simulation and 3D rendering free of charge for all serious inquiries. This is part of our pre-sale service — we want you to make an informed decision before committing.
What if I need custom specifications not in your catalog?+
Our OEM/ODM customization covers color temperature, beam angle, wattage, housing color, private labeling (DEM/DOM), and custom packaging. For structural modifications, we assess feasibility with our partner factories and provide a quote within 48 hours.
What does "tiered warranty" mean exactly?+
LED chips and drivers have different lifespans, so we cover them separately. Warranty periods vary by product series — for example, our industrial high-bay LED chips may carry a 5-year coverage while the driver is covered for 3 years. Exact terms are provided in your quote.
How do you handle quality issues found during inspection?+
If any unit fails inspection or aging test, it is immediately separated and replaced from stock. We do not ship partial orders — the full batch ships only after 100% pass. You receive the QC report showing all test results before shipment.
