Lighting Inspection
Your lights get checked at the factory before they ship. Our inspector tests electrical safety, function, labels and packaging against the sample and spec you approved — so problems get fixed at the factory, not after arrival.

What a Lighting Inspection Covers
Switching a lamp on is the easy part. Here is what else we check on every order.
Electrical ratings & wiring
Rating labels, wiring, strain relief, connectors and the adaptor or transformer — all checked against your approved spec, not the factory's word.
Function & controls
Every bulb and light section gets switched on. Switches, modes, timers, remotes, Wi-Fi and Bluetooth are tested the way your manual says they should work.
Assembly & workmanship
Sharp edges, damaged insulation, loose strain relief, bad welding, missing screws — each issue is photographed and graded critical, major or minor.
Labels, marks & barcodes
Rating plates, warnings, destination languages and market marks compared with your approved artwork. Every barcode is scanned, not just looked at.
Packaging & accessories
Cartons, inner protection, product position, accessories and shipping marks checked against your packing instruction.
Lighting Products We Inspect
If it plugs in, runs on batteries or lights up, we can inspect it.

Electrical Safety Tests, Done on Site
1,500–4,000 V
Hi-pot test
1,500 V for EU Class I, 4,000 V for Class II, 1,200 V for the US. One second, no breakdown.
≤ 0.1 Ω
Earth continuity
25 A at 12 V through the earth path of Class I products.
Rated input
Input power
Real power draw measured against the rating plate for your market.
Short-circuit
Adaptor check
Markings verified; the thermal fuse must trip without flame or molten parts.
Values come from our lighting working instruction. If your approved test document says something different, your document wins.
Performance and Build Quality
Light performance
30-minute warm-up, then power factor, color temperature, brightness and beam angle measured.
Wiring fixation
25 pulls at 40 N — rope lights at 60 N. Nothing may loosen or cut.
Internal build
Terminals, crimps, screws and insulation checked against the approved build.
Endurance
4 hours at rated voltage, then opened to check inside.
Marking rub
15-second wet cotton rub. Markings must stay readable.
Gasket check
Seals must stay in place at the lampholder when the lamp is removed.
What Goes Wrong in Lighting Orders
These are the problems that turn a good purchase order into returns, rework and bad reviews. We look for all of them.
Wrong adaptor or voltage for the marketA US-bound order with the wrong plug or input rating comes back as a container of returns.
Failed hi-pot testInsulation that breaks down under test voltage is a safety recall waiting to happen.
Loose strain reliefThe cord works loose from the lampholder after a few weeks of normal use.
Wrong color temperatureWarm white on the purchase order, cool white in the cartons.
Barcodes that don't scanYour warehouse or marketplace rejects the cartons at receiving.
Crushed cartons, missing accessoriesDamaged retail packs can't go on the shelf and incomplete sets come back.
Send Your PO and Specification
Our office team reviews your purchase order, SKU list, approved sample, drawings, rating information, packaging artwork, manual and barcode list — and confirms the checklist with you before anyone enters the factory.
Labels, Marks and Paperwork
Lighting products carry CE, UL, ETL, GS, RCM and other marks depending on the market. We check that what is printed on the product, the gift box and the cartons matches your approved artwork and documents — presence, position, model number and wording.
Rating plates and warnings — voltage, wattage, protection class, safety text and destination-language versions.
Mark consistency — the same model and mark information across product, adaptor, gift box and shipping carton.
Barcode and QR codes — scanned and decoded against your approved SKU and barcode list. 100% must scan.
Honest limits — we verify marks against your paperwork. We don't issue certificates, and a printed logo alone never proves a valid certificate.
Packaging and the Drop Test
A carton that survives the warehouse is part of product quality. When the drop test is in scope, the packed carton is dropped on one corner, three edges and six faces:
Under 21 lb (9.5 kg)Dropped from 30 in (76 cm)
21 to under 41 lb (18.6 kg)Dropped from 24 in (61 cm)
41 to under 61 lb (27.7 kg)Dropped from 18 in (46 cm)
After the drops, the carton must still protect the goods, the retail box must still be sellable, and every tested product must work. A carton that stays closed is not a pass if the product inside is damaged.
Coverage Across China and Asia

One booking, any stage
Early checks at 5–10% of production, mid-production checks at 30–50%, or a final random inspection when goods are finished and at least 80% packed.
Sampling to ANSI/ASQ Z1.4 (ISO 2859-1)
We sample by the standard US buyers know. Bigger lots get bigger samples, special tests use their own smaller samples, and the report states exactly how many units each test covered.
0
Critical
Nothing unsafe, ever. One critical finding fails the lot.
1.0
Major AQL
Problems that stop the product working or selling.
4.0
Minor AQL
Small cosmetic flaws that don't stop normal use.
These are our lighting working-instruction defaults. Your own approved criteria can replace them on any order.

A Report You Can Act On
The report shows production and packing status, lot size, sampled SKUs, the AQL applied, defect counts with photos, every test quantity, equipment settings and actual measurements — including any test that could not be performed and why.
Clear pass / fail / hold result so you can release, rework or reject with evidence in hand.
Re-inspection after rework confirms the fixes and checks for new problems before you ship.
An inspection does not replace certification or lab testing. We don't issue certificates, and the release decision always stays with you.

Frequently Asked Questions
Does a lighting inspection replace certification or lab testing?
No. Inspection verifies that sampled products match your approved spec and order requirements. It does not replace design validation, certification, laboratory testing or destination-market regulatory assessment.
Can I use my own checklist and AQL?
Yes. ANSI/ASQ Z1.4 at General Inspection Level II is our baseline, with Critical: none permitted, Major: AQL 1.0 and Minor: AQL 4.0 as defaults. Your checklist, defect history and AQL criteria can replace the defaults on any order.
Which tests apply to my product?
Tests are matched to your exact model, protection class, market, adaptor setup and approved spec. Typical items include hi-pot, earth continuity, input power, function and control checks, light performance, wiring fixation, internal construction, endurance, marking durability, barcode readability and a carton drop test where applicable.
What happens if defects are found?
Defective samples are labeled, photographed and classified in the report. You decide on rework, acceptance or rejection — a re-inspection can be booked after the factory reworks the goods.
How much does a lighting inspection cost?
Pricing is per inspector-day and depends on the factory location and the workload of your order. There are no travel fees and no weekend surcharges. Send your PO and factory address for an exact quote.
What do you need to book?
The purchase order, SKU breakdown, approved spec, approved sample references, drawings, rating information, packaging artwork, instruction manual, barcode list and any test requirements you want added.
