“Custom” is the most overused word in lighting supply. It can mean a different colour, a different drop length, or an entirely new housing. Those are four different projects with four different costs, and confusing them is how budgets slip.

The four levels of custom

Level	What changes	Tooling	Typical lead time
1. Configuration	CCT, wattage, beam, cable length	None	Standard
2. Finish & branding	RAL colour, logo, packaging	None, but batch minimum	+1–2 weeks
3. Adaptation	Modified housing, new diffuser, different driver position	Modified jig	+3–5 weeks
4. New design	New mould, new optics	Full tool	8–12 weeks

Most commercial projects need level 1 or 2 and are quoted as if they need level 4. Ask which level a quote is priced at.

Where custom actually pays back

Not in the fixture cost — custom is always more expensive per unit. It pays back in three places: matching a design language that cannot be bought off the shelf, avoiding a redesign fee from the lighting designer, and owning tooling that a competitor cannot buy. If none of those apply, buy standard.

What the factory needs from you

A brief that can be manufactured contains five things: a dimensioned drawing or reference photographs, the target retail or project price, the destination market, the installation environment, and the quantity expectation. Missing the target price is the most common gap — without it, engineering optimises for the wrong cost.

Photometrics before commitment

Custom housings change the optics. A new diffuser or a deeper recess moves the beam and the glare rating, which is why IES/LDT files are produced for the prototype, not for the catalogue equivalent. Approve the photometry before the tooling, not after.

Common failure modes

• Approving a sample photographed under showroom light instead of measuring it
• Leaving the IP rating to “we will make it IP65” without a test report
• Skipping the pilot run to save two weeks, then finding the issue at 5,000 units
• No written tooling ownership

Frequently asked questions

What counts as custom?

Four levels: configuration (CCT, wattage, cable), finish and branding, adaptation of an existing housing, and a new design with new tooling. They differ in cost and lead time by a factor of five.

Do I need a new mould?

Only at level 4. Most projects are solved by configuration or a modified housing, which avoids tooling cost and shortens the timeline.

What should I include in a brief?

A dimensioned drawing or reference photos, target price, destination market, installation environment and expected quantity.
