Complete fixture development
If a standard fixture has the wrong length, mount or diffuser, VST can develop the complete assembly. As a custom light fixture manufacturer, we specify the housing and building-supply connection together. The initial discussion identifies a workable construction and the sample needed to judge appearance and fit.
Start with a room photo, rough fixture size or sketch, and tell us which details are still undecided.
The linear pendant shown is one starting point for a custom light fixture. Position it around the task surface and ceiling support, then leave room to connect the supply and reach service parts.
Purchasing risk: Installation may need visible patching.
Confirm: Existing outlet position
VST solution direction: Set the mounting plate and cover outline together.
Purchasing risk: A small service job can require removing the whole fitting.
Confirm: Service side
VST solution direction: Provide access in the chosen end or canopy detail.
Purchasing risk: Source points may remain visible after assembly.
Confirm: Normal viewing angle
VST solution direction: Judge the optical stack in the complete sample.
At our custom light fixture factory, we first check whether available housings and optics suit the design. A change of length, finish or mount may retain those parts. A new section, light engine or attachment system needs a separate construction and tooling plan.
Length, cross-section and finish can follow the visible design. A new extrusion is considered when an available section cannot fit.
Buyer input: Visible envelope
Diffusion and source layout are selected together, including the space needed to hide direct source points.
Buyer input: Appearance target
Fixing slots, drop and cable-gripper locations can suit the ceiling interface without using the electrical lead as support.
Buyer input: Ceiling support
Supply interface, controls and access covers follow the chosen circuit and maintenance route.
Buyer input: Control system
Check which housing and assembly parts can stay. If a new construction solves an installation problem, weigh that benefit against the additional tooling and sample work. The complete fixture sample should settle the fit.
| Decision factor | Adapted Existing Platform | New Fixture Construction | Buyer guidance |
|---|---|---|---|
| Main change | Length, finish or attachment detail | New section, optical stack or frame | Keep available parts when they meet the visible and mounting requirements. |
| Tooling | May retain existing tools | May need dedicated extrusion or forming tools | Have the quotation identify tools separately from unit cost. |
| Service access | Follows available cover and end geometry | Can be designed around a new access route | Choose the service opening before closing the housing design. |
| Sample purpose | Prove the adaptation fits | Prove the whole construction and assembly | Evaluate the complete fixture in its intended position. |
VST coordinates the canopy, housing and optics as your custom light fixture supplier. The interface sketch shows how they fit together. An assembled sample checks that detail, and the packing layout sets out how the parts reach the installation.
VST work: Map the outlet and fixing positions to the canopy plate.
Stage output: Canopy outline and mounting-slot drawing.
VST work: Seat the full-length board and rigid diffuser in the housing.
Stage output: A closed optical sample for viewing at the intended angle.
VST work: Set both support cables and inspect the gripper engagement.
Stage output: A hanging sample with a defined support and lead route.
VST work: Separate the bar, canopy and coiled leads in protective supports.
Stage output: A carton layout and assembly contents list.
The custom light fixture manufacturer test plan covers the final assembly. These photographs show how it may be checked. Measurement results and acceptance records apply only to tests performed on the specified sample.
Purpose: Check the support path through cables and grippers.
Method: Mount the unpowered fixture on a rigid test rig with an inline load cell and apply the agreed loading procedure.
Acceptance criteria: No slip or damage under the project test condition.
Evidence: Suspension record after testing the selected assembly.
Purpose: Measure the selected light engine as assembled.
Method: Place the complete unlit bar inside a suitably sized sphere, route the feed, then close the enclosure for measurement.
Acceptance criteria: Measured light and color meet the agreed sample targets.
Evidence: Optical measurement sheet after the sphere test.
Purpose: Check that the lead jacket is retained at the housing.
Method: Inspect the grommet and flex the disconnected lead to locate poor seating or sharp-edge contact.
Acceptance criteria: The jacket stays seated and clear of damaging edges.
Evidence: Inspection record after checking the selected end assembly.
Purpose: Establish where the fixture sends light.
Method: Hold the bar rigidly at the goniophotometer rotation center and measure in a dark room.
Acceptance criteria: The resulting distribution supports the intended task layout.
Evidence: IES file or report after testing this fixture version.
Use the same fixture version on drawings and test files so later changes can be traced.
Shows fixture, canopy and mounting relationship.
Identifies the selected supply and control connection.
Contain results only for the actual tested configuration.
A light change to one custom light fixture model generally starts at 500 units. A new housing, optical system or substantial structural change usually starts at 1,000 units for that model. The quote names the construction covered.
VST can quote a complete sample as your custom light fixture supplier. Processing charges may apply, along with tooling costs for dedicated parts. Eligible sample spending may be returned or credited on a later order under agreed terms.
Light customization typically takes 15-25 working days for samples and 20-30 for bulk production. Deep customization typically takes 30-50 working days for samples and 25-35 for bulk production. These ranges depend on the settled construction and order conditions.
Dedicated dies, molds or assembly tools may carry a separate charge. The commercial terms can specify a tooling credit against the goods value of a later qualifying order, including the amount and conditions that apply.
Repeat orders for custom lighting fixtures use the released housing, diffuser and electrical version. With stable demand, VST can prepare or reserve agreed materials before future batches to keep supply steady and shorten replenishment times.
Protective packing can separate long housings from canopies and hardware. Carton quantities, labels, manuals and installation sheets can be customized for the way your team receives the fixture and assembles it on site.
You can request a quotation while the room concept is still taking shape. It should identify open electrical and mounting decisions and separate the lamp assembly from site work. Discuss mixed mounting types, an existing controller or drawing ownership before setting the sample brief. Include any requirement that the available construction options do not yet answer.
One appearance can be developed with different mounts as related variants. Each needs a separate interface and parts record, so the order clearly distinguishes the pendant from the surface fitting.
The quotation can separate the supply boundary.
| Scope | Identify in the quote |
|---|---|
| Fixture | Housing, light engine and mounting parts |
| Power | Driver supplied by VST or by the project |
| Controls | Required interface and external equipment |
Name the controller and required interface before selecting the driver. Physical connector fit alone does not establish control compatibility.
Exclusivity, drawing use and ownership of dedicated tools are commercial terms to discuss before development. They are not automatically included in a standard quotation.
