Two factories quote the same 1,200 mm brass ring chandelier. One says USD 640, the other USD 1,180. Both are honest. The difference is almost never margin — it is what each factory decided to include, and what each quietly substituted.
If you buy custom lighting for hotels, restaurants or multi-unit projects, learning to read a cost breakdown is the highest-return skill you can pick up. It lets you compare quotations that look nothing alike, tells you which line to push on, and stops you winning a price cut that reappears as a driver failing in year two.
This is how a custom lighting cost breakdown is actually built — the bill of materials, the labour behind it, and the choices that move the number far more than buyers expect.
What a BOM Is in a Lighting Factory
A bill of materials lists every physical part in one fixture, with quantity, material, finish and source. In a factory it is not a sales document — it is what purchasing works from, what the assembly line pulls against, and what the cost sheet is calculated from.
For a decorative fixture the BOM typically runs 40 to 150 line items; a large banquet chandelier with cut crystal can exceed 400. Every line carries a unit cost and a supplier, and every line is a place where a substitution can be made that you will not see in a photograph.
That is why two quotations for “the same” fixture diverge. They are not the same fixture. One has a brass frame, the other brass-plated steel; one uses a branded driver with five-year cover, the other an unbranded unit with twelve months. Both are legitimate products. They are not the same cost.
Our how to brief a lighting factory covers the input side, and the OEM manufacturing process covers what happens once the BOM is frozen.
The Eight Cost Blocks in a Custom Lighting Quote
Group those line items and every decorative fixture comes down to eight blocks. The percentages below are typical for a mid-to-large custom fixture in the USD 300 to 1,500 FOB band.
1. Metal structure and frame
Usually 18 to 30 per cent. This is the ring, arms, canopy, stem and internal support. Solid brass costs roughly three to five times mild steel per kilogram and machines differently, so the labour attached to it is higher too. Stainless sits between them; aluminium is cheapest but rarely gives the look a hospitality specifier wants.
This is also where the most consequential substitution happens: plated steel can look identical to brass on day one and differ completely by year three.
2. Shade and diffuser material
Typically 12 to 25 per cent. Hand-blown glass, machine-pressed glass, cut crystal, natural alabaster, acrylic and fabric all sit in very different bands. Crystal is graded — lead content, cut precision and facet polish move the price per bead by a factor of four or more within one supplier’s catalogue.
Natural stone such as alabaster is priced by block and grade, not by part, which is why a stone shade carries more unit-to-unit variation than any other material. Our comparison of alabaster, glass and acrylic shade materials covers the trade-offs.
3. Light source and driver
Roughly 10 to 20 per cent, and the block buyers underestimate most. The chip, driver, dimming protocol and thermal design decide whether the fixture still performs in year five. A branded driver with surge protection and flicker-free dimming can cost three times a generic unit — on a 60-fixture hotel order that is the difference between a maintenance budget and a maintenance crisis.
In North America the driver and assembly must also satisfy 120V or 277V at 60Hz, which narrows the supplier list and adds cost.
4. Surface finish
Around 8 to 15 per cent. A standard polished brass or matte black powder coat sits at the bottom; hand-applied antique finishes, living finishes meant to patina, custom-matched RAL colours and multi-step plating sit at the top, because each adds manual passes and each pass adds rejection risk.
Finishing is also where small orders get expensive: a custom colour carries a minimum batch charge from the plating shop whether you need 8 fixtures or 80.
5. Assembly, wiring and labour
Typically 12 to 20 per cent. A fixture that takes 40 minutes to assemble and one that takes four hours are different products even with an identical BOM. Crystal stringing, hand-wrapped joints, stone selection and matching, and complex suspension rigging are all labour — and labour is what separates a decorative manufacturer from an assembler.
6. Testing, certification and documentation
Usually 2 to 8 per cent on a repeat specification, more on a first one. Photometric testing, electrical safety testing, ingress protection verification and the accompanying file all cost money. Certification is supplied to your market requirement — CE (DoC with LVD/EMC/RoHS test reports), UKCA, UL/ETL, SAA, SASO, SONCAP and PVoC — and stated on your quotation. On a first order into a new market this block can spike — which is why it should be quoted separately rather than buried.
Our article on what OEM buyers must check in certificates explains what to look at, and how certification documentation is arranged covers the process.
7. Export packing
Three to 8 per cent, and the cheapest place to lose money. A large chandelier needs foam-in-place or an engineered crate, not a carton. Export packing for sea freight — double-wall cartons, corner protection, palletisation, desiccant, drop-tested — typically adds USD 12 to 45 per fixture. Skipping it saves 4 per cent and costs you a claim.
8. Factory overhead and margin
Ten to 20 per cent. This covers tooling amortisation where applicable, engineering time, QC labour, facility cost and margin. Any quotation that appears to carry no margin has moved the cost elsewhere — usually into a lower grade of component you never specified.
A Worked Example: 1,200 mm Brass Ring Chandelier
Here is how the blocks land on a real specification: a 1,200 mm suspended ring, solid brass frame, hand-blown opal glass globes, integrated LED at 3000K, dimmable driver, antique brass finish, quantity 12, for a hotel restaurant.
The frame is about 24 per cent — brass tube at this diameter is heavy, and the ring must be formed true, because an out-of-round ring reads from across a dining room. Glass globes are 18 per cent: twelve per fixture, hand-blown and matched for wall thickness. LED and driver are 15 per cent, because a driver that behaves on a restaurant dimming system is not the cheap one. Antique finish 12 per cent, assembly and wiring 16 per cent, testing 4 per cent, export packing 5 per cent. Overhead and margin take the remaining 6 per cent — low, because this is a repeat specification rather than a first build.
At quantity 12, that fixture lands in the USD 700 to 950 FOB band. At quantity 4 the same fixture lands 25 to 40 per cent higher, because the plating batch, glass setup and engineering time are fixed costs spread across fewer units. Nothing about the fixture changed — only the denominator.
This is the part of a MOQ, lead time and FOB discussion most buyers only discover on their second order.
What Moves the Number More Than Buyers Expect
Ask a buyer what drives cost and you will hear “size”. Size matters, but four other things matter more per unit of satisfaction.
Quantity. Plating batches, glass setups, first-article inspection and engineering are charged once. Spread across four fixtures or forty, the unit price difference is frequently 20 to 35 per cent for no design change.
Finish complexity. Moving from a standard powder coat to a hand-antiqued finish can add more per unit than adding 200 mm to the diameter, because each step is manual and each step adds rejection risk.
Driver specification. A USD 22 saving per fixture looks like USD 1,320 on a 60-fixture order. The first service call on a flickering dining room costs more than that.
Certification scope. Testing for one market is a line item; three markets with different voltage and documentation are three line items, and they do not discount linearly.
On very large or tall fixtures, engineering overtakes everything else — our guide to sizing a chandelier for high ceilings shows where that line sits.
Where You Can Cut Cost Without Hurting the Design
Some reductions are invisible. These are worth asking for.
Consolidate finishes. If your project has four custom finishes, ask what two would cost. Each is a separate plating batch with its own minimum.
Standardise the suspension. Custom drop lengths and bespoke canopies add engineering and assembly time. A standard rod-and-canopy set with field-adjustable length usually looks the same installed.
Order the full quantity once. Splitting 40 fixtures into two releases costs you the fixed-cost amortisation twice. If storage is the constraint, ask for staged delivery against a single production run — same price, no site problem.
Use a stock material in a custom form. A factory’s standard glass or stone in a new shape costs far less than a new material, because the supply chain exists. Our brass linear chandelier and crystal drum chandelier both began as standard material programmes with project dimensions.
Ask for value engineering, not a discount. Send the target price and ask what changes to reach it. You get a list of specific substitutions to accept or reject, instead of a number shaved off a specification you cannot see.
Where Cutting Cost Backfires
Three reductions reliably cost more than they save.
Plate instead of solid. On a frame anyone can touch — a stair rail, a bar footrest, a guest-room sconce — plating wears. On a chandelier three metres up it is frequently the right call. Know which you are buying.
Unbranded drivers. Driver failure is the most common warranty claim in decorative lighting. It is also the least visible line on a quotation, which is why it is the first thing cut.
Reduced packing. Four per cent saved against a 2 per cent damage rate is a bad trade, and the claim costs you weeks.
If a quotation is far below the others, ask which of these three it moved. A factory that will not say is telling you something.
What Our Quotations Include — and What They Do Not
Being explicit about scope prevents more disputes than any other habit.
A Staylighting quotation covers product cost, export packing, quality inspection and delivery to the Chinese sea freight loading port. It does not include international freight, insurance, customs clearance, import duty or destination port charges. The trade term is FOB China Port.
Set that out and the freight and duty conversation becomes a separate, manageable line. Our article on payment terms for lighting imports covers how money moves against that scope, and pre-shipment inspection covers how goods are verified before they leave.
How to Get an Accurate Quote on the First Pass
Most quotation rounds take three passes because the first is missing information. Send five things and you usually get a usable number immediately: dimensional drawings with suspension height and ceiling condition marked; material and finish specification, including whether plating is acceptable; light source requirements — colour temperature, output, dimming protocol, voltage; quantity split by fixture type; and destination market, which determines voltage and documentation.
Add your target price if you have one. It lets the factory engineer toward a number instead of guessing at your expectations. And if the design is still fluid, say so — a quotation on a fluid design is a budgeting exercise, and everyone should know that is what it is.
We have built decorative and architectural lighting in Zhongshan Guzhen since 2014, across five production lines with long-standing partner workshops for specialist processes. That matters here because the choice between in-house and partner work is made on capability, not availability — and you get told which is which.
Frequently Asked Questions
Why do two factories quote so differently for what looks like the same chandelier?
Because it is not the same chandelier. The differences are usually frame material (solid brass versus plated steel), driver brand and specification, crystal or glass grade, and finishing steps. Ask for a specification sheet rather than comparing photographs — the photograph shows none of the four.
Can I get a cost breakdown with my quotation?
Yes, and you should ask as a matter of routine. A factory willing to show the blocks is a factory willing to discuss them. We separate fixed costs — tooling, plating batch, glass setup — from unit costs, so you can see what a quantity change does to the price.
How much does quantity change the unit price?
Typically 20 to 35 per cent between a four-unit and a forty-unit run of the same design. The mechanism is fixed-cost amortisation: plating minimums, glass setup, engineering and first-article inspection are charged once regardless of how many fixtures they are spread across.
Are tooling and mould charges refundable?
Generally not — a mould cut for your design has no second buyer. Worth agreeing in writing: the tooling is yours, it will not be used for another customer, and the repeat order does not carry the charge again. On many designs tooling is avoidable by working within existing component ranges.
What exactly does a FOB China Port price cover?
Product cost, export packing, quality inspection and delivery to the Chinese sea freight loading port. It excludes international freight, insurance, customs clearance, import duty and destination port charges. Budget roughly 1.5 to 1.6 times FOB for landed cost into the United States at current duty rates on lighting.
