Craft décor on a bought-in lighting chain
Lit festive décor is shown under Christmas and festive décor and lamps and lighting at the IHGF Delhi Fair, run by the Export Promotion Council for Handicrafts. In handicraft orders the decorative part is usually made by hand: paper stars, fabric or jute balls, metal or wooden shapes, glass lanterns. The lighting part (the LED chain, battery box, controller or plug-in adaptor) is usually bought in and fitted by the décor maker.
That split decides the risks. Whether a set can be sold depends on parts the décor maker did not make and may not understand: the wire gauge, the adaptor, the battery box. Meanwhile the craft work adds its own electrical risks: a shade glued over a lamp holder, a cable pinched by a metal shape, a wire threaded through a sharp hole.
Two families need different checks. Mains sets plug into the wall, directly or through an adaptor, and bring shock and fire risk. Battery sets run at low voltage but bring battery-box, coin-cell and leakage risks. Plain light-free decorations are covered on Christmas and festive decorations.
What we check on string lights and LED décor
| Check | How it is checked | What fails |
|---|---|---|
| Function | Every sampled set lit at rated voltage or with fresh batteries; each mode, timer and switch operated | Dead LEDs, sections out, flicker, timer or controller faults |
| Dielectric strength (mains sets) | Hi-pot test between live parts and accessible surfaces on a calibrated tester, at the level the buyer's lab gives | Breakdown or leakage above the limit |
| Cable and joint pull | Firm pull at the plug, controller, end connector and several lamp holders; cable checked where it passes through décor | Conductors move at terminals, insulation cut or pinched |
| LED and cap retention | Caps and covers pulled and twisted | Caps come off exposing contacts, or form small parts |
| Battery box | Cover closure tried by hand; screw fixing checked; batteries fitted and removed as a user would | Cover opens without a tool where one is required, battery contacts loose, polarity marking missing |
| Adaptor and plug | Adaptor marks, ratings and model compared with the certificate; plug type checked for the market | Uncertified or different adaptor, wrong plug, no rating |
| Outdoor sets | IP marking, seals at connectors and battery box checked visually | Outdoor claim without an IP rating, open or missing seals |
| Markings and leaflet | Rating label, indoor/outdoor wording, warnings, instructions in the market's languages | Missing or wrong markings, no instructions |
These are checks on production against what was certified. Type testing to UL 588 or EN 60598-2-20 is done by an accredited laboratory.
Common festive string lights and LED décor defects and how they are classed
| Defect | Class |
|---|---|
| Hi-pot failure, exposed live part, cut insulation | Critical |
| Coin cell reachable without a tool on a product that requires a secured compartment | Critical |
| Uncertified adaptor or wrong plug for the market | Critical |
| Section of LEDs dead, controller mode not working | Major |
| Outdoor set without IP marking | Major |
| Shade glued crooked, paper torn, metal shape scratched | Minor (major if clearly visible) |
One electrical failure in the sample usually means the whole lot is held until every set is tested and the cause found.
Market rules and certification
- United States. UL 588 covers temporary-use seasonal decorative lighting and accessories with an input of up to 120 V; listing is by an NRTL such as UL or Intertek (ETL). Under 16 CFR 1120, plug-in seasonal lighting that lacks UL 588's minimum wire size, strain relief or overcurrent protection is a substantial product hazard. See UL and ETL listing.
- US coin cells. 16 CFR 1263 (Reese's Law) requires consumer products containing button or coin batteries to meet ANSI/UL 4200A-2023, which covers how securely the battery is held and warnings. Children's products also need third-party testing.
- European Union. Mains sets fall under the Low Voltage Directive (50 to 1,000 V AC) and usually the EMC Directive; IEC/EN 60598-2-20 covers lighting chains for indoor or outdoor use at supply voltages up to 250 V. RoHS and WEEE apply to the electrical parts. See CE, LVD and EMC and RoHS and WEEE. Battery-only sets below the LVD range still fall under the GPSR.
- United Kingdom. UKCA or CE marking; see UKCA and CE marking.
The inspector checks that the certificate or listing names this model and that the parts fitted match the parts tested.
Packing, transit and your purchase order
String lights are wound on cards or reels so they unwind without tangling; tight winding can kink cable and stress joints. Batteries are best shipped out of the box or with an isolating tab so sets do not drain or switch on in transit. Paper and fabric shades crush, and glass lanterns need cells. Seasonal goods also face a fixed sale date, so check carton counts and marks closely.
- Market, supply type (mains, adaptor or battery), plug type and adaptor model.
- Certified LED chain, controller and adaptor, with the lab report or listing.
- Indoor or outdoor use and IP rating.
- Battery type, compartment closure, and whether batteries ship fitted.
- Electrical tests for the inspection, with values from your lab.
- Markings, instructions, warnings and packing.
Plan a during-production inspection for seasonal orders. For plug-in lamps, see table and floor lamps.
