LED Driver OEM Sourcing in China
Compare China LED driver OEM suppliers by constant current vs constant voltage, Vf / LED string voltage, output current and wattage, dimming (0–10V, DALI, TRIAC, PWM), IP and PFC claims, housing, private label, MOQ, samples and documents — buyer-side RFQ fields, not factory marketing.
Buyer context
Make the technical and commercial basis comparable first.
LED driver quotations often look similar until topology (CC vs CV), Vf window, output current/wattage, dimming protocol, IP / PFC / efficiency claims, housing form factor, private-label scope and MOQ/NRE layers are written down. Sephalis helps buyers make those fields explicit so quotations stay comparable, and keeps supplier statements separate from electrical safety approval or market-access certification. Sephalis does not manufacture LED drivers and does not certify electrical safety, IP performance or market-access marks. Use this page for LED lighting drivers (fixture / strip / outdoor driver modules); for fixed-output device PSUs with barrel or other non-USB DC connectors use /electronics-sourcing-china/power-adapters; for USB / GaN wall bricks use /electronics-sourcing-china/wall-chargers.
What buyers usually need to compare
Use these fields to keep quotations tied to the same technical, production and packaging assumptions.
✓ Topology: constant current (CC) vs constant voltage (CV) vs constant-power / programmable current; channel count if multi-output
✓ Output current target or adjustable range (mA/A) and rated wattage
✓ Vf / LED string voltage window (or fixed CV voltage such as 12V/24V/36V/48V) matching the LED load
✓ Input voltage range and frequency expectation (for example 100–240 VAC or 100–277 VAC)
✓ Dimming requirement — none / 0–10V / DALI(-2) / TRIAC-phase / PWM / multi-mode — and who states compatibility
✓ IP / environmental rating requested (IP20 / IP65 / IP67 or dry-damp note) — RFQ field, not a Sephalis guarantee
✓ PFC / power-factor and efficiency targets requested and who states them (supplier claim)
✓ Form factor / housing — plastic vs metal/aluminum, slim profile, junction-box style, mounting, cable exits
✓ Protection features requested (OVP, OCP, SCP, OTP, surge) as RFQ fields, not Sephalis guarantees
✓ Destination markets and labeling / marking language expectations
✓ Private-label and OEM customisation tier (logo/label/pack vs housing/cable vs new platform / full ODM; firmware if dimming custom)
✓ MOQ by SKU and by customisation layer (product vs packaging vs tooling/NRE); sample cost and sample lead time
✓ Production lead time, quantity breakpoints, and NRE scope (PCB / firmware / cert extension) when custom
✓ Documents to request with the quotation (datasheet matching RFQ fields; cert/test copies if claimed)
Evidence worth collecting before the next decision
Sephalis keeps supplier statements, technical evidence and unresolved questions separate so the buyer can see what is known and what still needs engineering or specialist review.
✓ Written electrical specification matching RFQ fields (topology, Vf/current/wattage, input) — buyer-verified once agreed
✓ Supplier dimming-protocol statement / compatibility note (supplier claim)
✓ Product label / rating-plate artwork draft (including private-label if in scope) (supplier-provided)
✓ Supplier statement on IP rating, PFC / PF, and efficiency (supplier claim)
✓ Housing / outline drawing or dimensioned note when form factor is critical (supplier-provided / commercial)
✓ Written sample terms and production lead time (commercial)
✓ Quotation with MOQ, OEM tier, NRE/tooling and exclusions (commercial)
✓ Supplier-provided test reports or certificate copies (UL/CE/FCC/CCC/etc.) where offered (supplier claim / document — not Sephalis certification or market approval)
✓ Unresolved items called out as unknown until buyer or specialist closes them (report-to-model match, independent lab status, measured PF/THD/efficiency vs claim, dimming-compatibility on buyer control gear, IP test configuration)
Commercial comparison
Separate one-time development cost from recurring unit cost.
For electronics, tooling, NRE, programming, test fixtures, artwork and prototype charges may sit outside the production unit price. A useful comparison keeps those charges visible together with MOQ, lead time, packaging and FOB terms.
Technical boundary
Supplier documents are evidence, not automatic approval.
Sephalis can collect specifications, quotations, supplier documents and samples. Formal electrical safety, radio, battery transport, engineering validation, product compliance and market-access decisions remain separate questions for the relevant specialists and authorities.
Common buyer questions
Short answers below describe the sourcing workflow rather than engineering or regulatory approval.
When should I use led-drivers vs power-adapters, wall-chargers, power-banks, pcb-assembly or electronic-enclosures?
Use /electronics-sourcing-china/led-drivers for LED lighting drivers specified by CC/CV, Vf/current, dimming, IP/PFC claims and driver housing. Use /electronics-sourcing-china/power-adapters for AC/DC device PSUs matched by fixed output V/I, polarity and barrel or other non-USB DC (not a lighting-driver RFQ). Use /electronics-sourcing-china/wall-chargers for USB / GaN wall bricks with PD/PPS. Use /electronics-sourcing-china/power-banks for portable battery packs. Use /electronics-sourcing-china/pcb-assembly when the RFQ is bare board fab/assembly of a driver PCB (Gerber/BOM/SMT) without buying a finished driver module. Use /electronics-sourcing-china/electronic-enclosures for empty housing only. For a separate metal heatsink RFQ (extruded/skived/bonded-fin/CNC — not the driver module), use /electronics-sourcing-china/heatsinks. For a separate equipment cooling fan RFQ (discrete DC axial or blower — not the driver module’s thermal or housing field), use /electronics-sourcing-china/cooling-fans. If a 12V/24V CV supply is for LED strip/lighting with dimming/IP/PFC fields, keep it on led-drivers; if it is a non-lighting device supply matched by polarity + barrel, use power-adapters. If a project needs more than one product type, run separate RFQs so quotations stay comparable.
Does Sephalis manufacture or certify LED drivers?
No. Sephalis is a buyer-side sourcing and supplier-research service. It helps compare manufacturers and collect specifications, quotations, samples and supplier documents. Manufacturing capability claims and any certificates remain with the supplier; formal electrical safety or market-access approval stays with the relevant specialists.
How should UL / CE / FCC / CCC (and similar) claims be used?
List destination markets in the RFQ and request matching documents for the exact model being quoted. Treat certificates and test notes as evidence to collect and review — supplier claims or documents, not automatic import approval or a Sephalis guarantee. If report-to-model match or independent lab status is unclear, mark that item unknown until the buyer or a specialist closes it.
How should MOQ, private label and NRE be compared?
Ask each supplier to separate logo/label-only, housing/cable customisation and full custom/ODM (including firmware or new platform) paths, and to split product MOQ from packaging or tooling/NRE. Sample cost and sample lead time should sit outside production MOQ. A low MOQ claim is not comparable until those lines are written down.
Why must CC vs CV and dimming appear in the RFQ?
Constant-current and constant-voltage drivers are not interchangeable for the same LED load; Vf window and current must match the LED string or strip. Dimming protocol (0–10V, DALI, TRIAC, PWM, or none) changes the product and compatibility assumptions. Lock topology, electrical window and dimming before comparing price. Prefer qualified OEM / private-label RFQs over DIY LED-strip keyword chasing.
How should IP rating and efficiency / PFC claims be treated?
Put the target IP and any PF/efficiency expectation in the RFQ; request the supplier’s written statement and any test report for the configuration quoted. Treat IP67 / high-PFC / efficiency % marketing as supplier claims until documents and (where needed) independent review close them — not Sephalis-tested performance.
