Why Choose JSD
Not just a factory.
An engineering partner.
We built JSD around one reality: overseas lighting engineers and contractors need more than catalog products. They need custom specs, verified quality, and a supplier that doesn't disappear after the sample.
Our edge
Built different, by design
Four pillars that separate us from catalog factories and resellers.
Private-mold aluminum housing
Our in-house pressure-die-cast molds mean your product looks nothing like the flooded public-mold market. Adjust CCT, wattage, beam angle, and standard dimensions without opening new tooling. Need a fully custom structure? We quote mold cost and timeline transparently -- no surprises.
- AL6063 extrusion + die-cast options
- New tooling: ~18,000-45,000 RMB, 45-60 days
- Exclusive exterior -- no catalog look-alikes
1-2 pcs sampling, no MOQ
Most factories reject small sample runs. We accept 1-2 piece orders for validation. Sample fee is charged upfront and fully refunded when you place your volume order. You control testing before committing -- that's how it should work.
- Sample fee refunded on bulk order
- No minimum quantity for production orders
- Repeat customers skip sampling for verified SKUs
100% aging test & full inspection
Every single unit goes through burn-in aging, photometric verification, and visual QC before it leaves the factory. We send shipment confirmation video before you release final payment. No hidden deviations, no batch surprises at destination.
- Aging test mandatory -- no exceptions
- Pre-shipment video confirmation
- LM-80 & IES photometric files on request
CE · RoHS · ErP · SASO compliance
Valid, up-to-date certificates with matching model numbers and labels. We support EU tender packages with IES files, LM-80 reports, and carbon footprint data. ESPR/DPP readiness for forward-looking procurement requirements.
- EU: CE, RoHS, ErP -- current DoC
- Middle East: SASO / ESMA
- DPP / ESPR documentation on request

How it works
Transparent process,
no hidden steps
Every engagement follows the same documented flow -- from first inquiry to goods-in-hand confirmation. No verbal-only commitments.
-
1
Inquiry & spec confirmation
Share parameters, quantity, application, target market, and compliance requirements. We confirm feasibility and issue a written quotation (EXW Shenzhen default).
-
2
Sample (1-2 pcs) with test report
Sample fee charged upfront and refunded on volume order. You arrange international shipping and customs. Sample production: 10-20 days for existing molds.
-
3
30% deposit → production start
Deposit triggers production scheduling. BOM is locked; key components verified against spec before assembly begins.
-
4
Aging test · full QC · video confirmation
Every unit aged and inspected. Shipment video sent for your review and approval before final payment is requested.
-
5
70% balance → shipment
Full payment received, goods dispatched. Tracking and shipping documents provided promptly.
Key policies -- written, not verbal
Sample fee refund guarantee
Sample cost is deducted from your first volume order invoice -- no ambiguity, no negotiation needed later.
BOM lock -- no silent substitutions
Bill of materials is confirmed before production. Critical components (driver IC, LED chip) verified against spec. No downgrade without written consent.
Shipment video -- always
You see the packed goods before releasing final payment. No exceptions. This is our standard, not a premium service.
Flexible trade terms
Default EXW Shenzhen. FOB and CIF available on request. 30/70 payment split is standard -- no OA or open-account terms.
Verified repeat customers -- simplified flow
Established clients reordering validated SKUs can skip sampling and pre-production testing, reducing lead time significantly.
Right fit
Who we work best with
We're selective. The right partnership benefits both sides.
Overseas contractors
Hotel, retail, office, and showroom projects. Need spec flexibility, sample validation, and reliable batch consistency.
Importers & distributors
Local distribution with fluctuating order volumes. Need trial orders, delivery reliability, and consistent quality across batches.
Overseas brand sellers
E-commerce or independent store brands. Differentiated private-mold appearance, small test runs, high batch-to-batch consistency.
Chain stores & real estate
Direct procurement with strict approval processes. Need full documentation, samples with test reports, and firm delivery commitments.
