Operational Reality

Zero-Friction International Spare Parts Policy

Unlike domestic consumer brands, cross-border lighting engineering requires pragmatic, swift resolution. Returning defective items internationally to China incurs heavy customs and delays your job-site handover.

✓
No Mandatory Return for Low-Quantity Defects Defects under standard project threshold (<5 pcs or isolated failures) are verified purely via high-res video, wiring schematics, and serial logs. No physical return to China required.
✓
Air Express Parts Dispatch Urgent project rectifications receive priority air courier dispatch (DHL / FedEx / UPS) with exact batch-matched color binning and CCT tolerance.
✓
Consolidated Bulk Replacements Non-urgent spare component replenishments or preventive reserve packages can be consolidated with your next container / LCL shipment.

Warranty Coverage Boundaries According to ISO9001 & CE Compliance

Covered by Jarstar (JST)
  • • Driver premature failure under specified input voltage range (±10%).
  • • LED COB / SMD chip failure, visible flickering, or dead light nodes.
  • • Luminous decay exceeding standard L80 limits within warranty duration.
  • • Factory casting defects, paint blistering, or assembly anomalies.
  • • Optical yellowing or lens warping under rated junction temperatures.
Excluded Conditions
  • • Extreme grid surges exceeding driver surge rating without external SPD.
  • • Direct water ingress on indoor IP20 rated luminaires.
  • • Hot-plugging magnetic track heads under live DC load (unless specified).
  • • Unauthorized rewiring, physical impact, or job-site structural damage.
  • • Local on-site electrician labor costs (only free components supplied).

B2B Clarifications

After-Sales & Warranty FAQ

Transparent answers regarding overseas liability, spare parts logistics, and maintenance.

Do we have to send defective luminaires back to China for warranty verification? +
In standard project claims, no physical return to China is required. We recognize that international customs clearance and freight make unit returns inefficient. As long as you submit clear photographic evidence, video logs of the electrical fault, and driver serial numbers, our factory engineers will approve the claim and immediately dispatch replacements.
How do you guarantee that replacement LED modules match the original color binning? +
Every production batch is archived with its original LED Binning Code (MacAdam ≤ 3 SDCM) and driver lot number. When preparing replacement COB engines or modules, our engineering workshop references your specific project BOM archive to ensure consistent chromaticity, lumen output, and beam angle uniformity without visible field deviation.
Who bears international freight and customs costs for warranty replacement parts? +
For verified product defects within the standard warranty timeframe, Jasda (JSD) pays 100% of the replacement component cost and international air freight (DHL/FedEx) directly to your designated hub. Local destination import duties/taxes (if incurred under sample classification) follow standard international trade practice.
Are on-site installation labor and scaffolding costs reimbursed? +
Consistent with standard international B2B lighting manufacturing terms (EXW / FOB contracts), our warranty is limited to free factory component/fixture replacement and technical support. We do not provide local on-site contractor labor compensation. To minimize field labor risks, 100% of our luminaires undergo multi-stage burn-in and aging tests prior to export packaging.
Can we request an extra 1-2% spare parts package with our initial bulk order? +
Yes, this is highly recommended for hotel, mall, and commercial tender projects. We can include a pre-tested backup package (extra drivers, magnetic insert modules, and optical accessories) directly in your main container shipment at cost price to provide immediate on-site redundancy.
