Custom LED Assemblies, Built to Your Drawing

Send us the LED strip connector part number and the length. It comes back soldered, sleeved, sealed and tested — ready to drop into your product. This is not a service we bolt on; it is most of what we build. Everything else on the SuperLightingLED site ships from stock in 24–48 hours — this page is for the jobs where the stock length, connector or colour temperature is not the one you need. One piece or ten thousand: the production floor is ours, so there is no minimum to argue about.

Your LED strip connector
Molex, JST, TE, or whatever mates with your equipment. Factory-fitted, not hand-soldered on site.
Your length
1.75m, 2.65m, 22cm tails — cut at the correct points and sealed. Not reel lengths.
Your build
Silicone extrusion, over-moulding, one-piece end exits, pre-assembled and powered up before packing.
01 — The problem this solves

If you build equipment, the lighting is never the hard part — the interface is.

What normally happens

You buy LED strip on a reel and LED strip connectors in a bag. Somebody on your line cuts, LED strip lights, solders and heat-shrinks every unit by hand. It works, until volume rises: the joints become the failure mode, the labour cost becomes visible, and every returned unit has a hand-made joint in it.

What we do instead

You send the mating connector part number and the finished length. We build the assembly at the factory — correct polarity, correct wire gauge, strain relief, sealed exit — and test every one. Your line plugs it in.

Why it is cheaper, not dearer

One assembly operation at source beats hundreds on your bench, and the failure rate drops with it. For repeat volume the unit price normally lands under “LED strip light + LED strip connector + your labour”.
02 — LED strip connector termination

The part most suppliers will not touch. It is routine work here.

Tell us the part number of the LED strip connector on your equipment and we fit the mating half to the LED strip light. Housing, terminals, wire gauge, tail length, pin order — all to your specification. If you are not sure of the part number, send a photograph of the socket with something for scale and we will identify it.

The build, photographed on our floor

Tap any photo to enlarge

One order, start to finish: bare terminals, crimped leads, the connector your equipment uses, soldered to the LED neon flex, sealed and lit. These are our own production photos, not stock images.

01

Terminals to suit your connector

Your connector series decides the terminal, so we buy that exact part on the reel. Nothing is substituted for something close.

02

Crimped to your wire gauge

Every core is stripped to length, crimped and pull-checked. Your drawing sets the gauge, the colour code and the outer diameter — 22 AWG four-core here.

03

The housing that mates with your equipment

We fit the mating half of the LED strip connector already on your equipment — Molex, JST, TE, Hirose, Amphenol, Deutsch, JAE, any series.

05

Soldered to the LED strip light or LED neon flex

Cut to your exact length, soldered to the pads, and the cut end sealed with an end cap. It happens here, not on your bench.

06

Powered and checked before packing

Every assembly is powered up and checked — polarity, colour order, data direction, full length lit — then coiled and packed.

Pin order is checked, not assumed

Getting polarity or data-line order wrong on a few thousand assemblies is an expensive mistake, so we do not infer it. We send back a written pinout — which colour goes to which pin, in your LED strip connector’s numbering — and we do not start production until you have confirmed it. On first orders we will normally build and ship a small number of pieces for you to fit-test before the balance runs. SuperLightingLED has worked that way since we started building to drawings — it catches wrong part numbers and mirrored pin orders while they still cost nothing to fix.

03 — A live example

One line from a repeat customer’s order, reproduced as written.

901 pcs × 1.75 m — TM1934 2835 RGB, 20 segments, 120 LED, 10 mm, 24 V, IP20 bare board, adhesive backing, break-point resume. Input terminated with Molex 52266-0411.

901 pcs × 2.65 m — same specification. Input Molex 52266-0411, output Molex 52213-0411.

Why it repeats

Nothing on their assembly line touches a soldering iron. The specification is on file here, so the second order is a purchase order rather than a new engineering exercise.

Two different lengths, one order

1.75 m and 2.65 m in the same shipment, each with its own termination. Mixed lengths on one order are normal — they do not attract a set-up charge each.

Reordering years later

We hold the exact build sheet, not just the model number. See lifetime support — a reorder in year five matches the one from year one.
04 — Beyond termination

Cutting and soldering is the entry level. These are the jobs that need a factory.

90° corner, mitred and joined. Two lengths of trimless plaster-in LED aluminium profile cut and fitted so the lit line turns a corner without a break or a visible joint.

Any angle, and the diffuser follows it. The cover is cut to the same angle as the LED aluminium profile, so the light line stays continuous through the bend — this is what a site drawing with a non-90° corner actually needs.
LED aluminium profile

Silicone extrusion

Custom silicone LED aluminium profile extruded around the LED strip light — side-emitting, top-emitting, or a shaped section to suit the fixture. See the neon profile range for the standard sections.
Sealing

Over-moulding & end caps

End caps moulded on rather than glued, with the cable exiting where you need it — including a side exit rather than the end. Waterproof and mechanically strong, and it looks finished.
Sealing

One-piece cable exit

Cable, seal and LED aluminium profile formed as a single part. No joint to leak, nothing for an installer to get wrong on site.
Assembly

Assembled kits

LED strip light, LED driver, LED controller, LED aluminium channel, cabling and fixings — matched, powered up together and packed as one kit.
Board

Custom PCB layouts

Segment length, LED pitch, cut-point spacing, copper weight for long runs, dual-row for higher output.
Branding

Private label

Your reel labels, your printed packaging, your part numbers on the packing list. Nothing of ours in the box.
05 — Who this is for

The pattern is always the same: a piece of equipment that needs light inside it, with an LED strip connector already decided.

Equipment & machinery

Enclosure and panel lighting, indicator LED strip lights, inspection lighting. Usually 24 V, usually a fixed LED strip connector already specified by the electrical designer.

Vehicles & mobility

Interior and accent lighting, service vehicle lighting, marine and caravan fit-outs. Vibration and temperature drive the specification here more than brightness does.

Robotics, drones & models

Status and signalling lights where weight and cable dressing matter. Short tails, small LED strip connectors, addressable pixel LED strip light for status colour.

EV charging & infrastructure

Status rings and indicator lighting in outdoor housings — IP rating and UV stability matter more than anything else. See outdoor range.

Signage & display builders

Repeatable modules at a fixed length, terminated so the installer only ever plugs in.

Furniture & cabinetry

Pre-cut, pre-terminated lengths shipped flat-pack with the carcass, so the fitter does no wiring.

Not sure which LED strip connector your equipment uses?

Send a photo of the socket — straight on, with a ruler or a coin next to it — plus the pin count and the voltage. We identify LED strip connectors from photographs regularly, and we would rather spend ten minutes doing that than have you order the wrong mating half. Browse LED connectors and accessories to see the standard parts we already stock.

06 — How the process runs

Three stages before production, and none of them costs you anything.

1

Enquiry

Send the specification, a drawing, a sample, or a photograph. If you only know the outcome you need — “this housing has to glow evenly, it runs at 24 V, and it lives outdoors” — that is enough to start.
2

Specification & quotation

We come back with a written build sheet: LED strip light type, pinout, wire gauge, tail lengths, sealing method, plus unit price, tooling cost if any, and lead time. Anything we think will cause a problem is flagged here, not later.
3

Sample, then production

For a new build we make samples first and you fit-test them. Production starts only after you confirm. Every unit is tested before packing, and the build sheet stays on file for reorders.

07 — What to send us

The more of this you can answer, the faster and tighter the quotation comes back.

Electrical

Voltage, LED strip connector part number, pin order, wire gauge and outer diameter, tail length at each end.

Optical

Colour temperature or colour, LED density, output level, CRI if it matters, diffusion required or not.

Mechanical

Finished length, bend radius, mounting method, IP rating, operating temperature range.

Commercial

Quantity for the first order, likely annual volume, destination country, and the date you need it by.

Missing several of these is normal on a first enquiry. Send what you have — the specification is a conversation, and it is one we have several times a week.

Start a custom build

Send a part number, a drawing, a photograph of the LED strip connector, or a description of the job. All of them are a valid starting point. A person replies, normally within one business day.

Custom assemblies carry the same SuperLightingLED warranty as our standard products — see warranty & lifetime support. Tooling costs, where any apply, are quoted separately and stated up front.
