How Long Does Custom Lighting Take?

Custom lighting timeline overview

One of the first questions clients ask about custom lighting is: "How long will it take?" And the answer is almost always longer than they expect. Custom architectural lighting is a bespoke product — each piece is designed and built from scratch. It is not something you can pick up from a warehouse.

That said, custom lighting does not have to be a black box. With a clear understanding of the process and the factors that affect timing, you can plan accurately and avoid schedule surprises.

This guide walks through each stage of the custom lighting process, explains typical durations, and identifies what you can do to keep things moving. The timelines here are based on our experience with custom lighting projects across the GCC, from single decorative pieces to full-project custom fixture packages.

Stage 1: Initial brief and quotation

Duration: 1–3 weeks

Every custom project starts with a brief. The more information you provide at this stage — drawings, reference images, dimensions, performance requirements — the faster we can respond with a proposal and quotation.

What happens during this stage:

• We review your brief, drawings, and reference images
• Our engineering team assesses feasibility and identifies potential challenges
• We develop a preliminary design concept and budget estimate
• We send you a proposal with scope, timeline, and pricing

How you can speed this up:

• Provide clear drawings with dimensions
• Share reference images of the aesthetic you want
• Specify technical requirements (output, color temperature, CRI, IP rating, dimming)
• Identify your budget range — this helps us propose appropriate solutions

Stage 2: Concept design

Duration: 2–4 weeks

Once the proposal is accepted and the project kicks off, we move into concept design. This is where the design is developed and refined before we go into engineering.

What happens during concept design:

• 3D modeling of the fixture(s)
• Material and finish selection
• Light source and optical layout
• Concept renders for client review
• 2–3 rounds of design revisions based on feedback

This stage ends with a signed-off design concept: drawings, renders, and specification that everyone agrees on. The faster the review and approval cycle, the shorter this stage takes.

Stage 3: Engineering and technical design

Duration: 2–4 weeks

Once the concept is approved, the design moves to the engineering team. This is where the pretty pictures become a manufacturable product.

What happens during engineering:

• Detailed mechanical design — every component, every dimension
• Electrical design — LED selection, driver specification, wiring diagrams
• Thermal analysis — ensuring the fixture will not overheat
• Structural engineering — especially important for large and suspended fixtures
• Production drawings and BOM (bill of materials)
• Internal design review for manufacturability

For complex or large fixtures, this stage may include structural calculations and load analysis. Safety is critical — a custom chandelier falling from a ceiling is not an acceptable outcome.

Stage 4: Prototype and sample approval

Duration: 3–6 weeks

This is the most important stage for quality assurance. We make a physical prototype (or sample) of the fixture so you can see, touch, and test it before we go into full production.

What happens during prototyping:

• Fabrication of a 1:1 prototype (or a representative section for very large pieces)
• Finish and color sample preparation
• Electrical assembly and initial testing
• Photometric verification — does it produce the light we promised?
• Client review and approval
• Any necessary design adjustments and re-prototyping

Do not skip the prototype stage. It is much cheaper and faster to fix problems at prototype stage than it is to fix them after production. We have had projects where the prototype revealed issues that no amount of 3D rendering could have predicted. Catching those issues early saved weeks of rework and thousands of dollars.

Stage 5: Production and manufacturing

Duration: 4–10 weeks

Once the prototype is approved, we go into full production. The duration depends on the complexity and quantity of the fixtures.

Production timeline by complexity:

• Simple custom (modified standard): 3–5 weeks
• Moderate complexity (custom pendant, wall sconce): 5–8 weeks
• High complexity (chandelier, large feature fixture): 8–12 weeks
• Very high complexity (sculptural, one-of-a-kind): 12–24 weeks

Production involves multiple steps — metalwork, finishing (painting, plating, polishing), glasswork, electrical assembly, and final assembly. Each of these steps has its own lead time, and they often need to happen in sequence.

Stage 6: Quality control and testing

Duration: 1–2 weeks

Before anything leaves the factory, it goes through quality control. This is not optional — it is how we ensure that what arrives on site matches what was approved.

What quality control includes:

• Visual inspection — finish quality, alignment, workmanship
• Electrical testing — function, wattage, insulation resistance
• Photometric verification — output and beam pattern
• Color consistency check — all fixtures match within specification
• Burn-in testing — running fixtures for 24–72 hours to catch early failures
• Packaging review — ensuring proper protection for shipping
• Documentation — test reports, certification, installation instructions

For large orders, we typically inspect 100% of the first article and then do AQL sampling on the rest. For critical or high-value pieces, 100% inspection is standard.

Stage 7: Shipping and logistics

Duration: 2–8 weeks

Getting custom lighting from the factory to the project site involves more than just putting it on a ship. There is documentation, customs clearance, certification, and inland transport to coordinate.

Customs and certification considerations:

• SASO certification for Saudi Arabia adds 1–2 weeks if not already in place
• ESMA / ECAS certification for the UAE adds 1–2 weeks
• Qatar, Kuwait, and Oman have their own certification requirements
• Customs clearance can be delayed if documentation is incomplete — always use an experienced freight forwarder

Stage 8: Installation and commissioning

Duration: 1–4 weeks (varies by project size)

Installation is the final step. Custom fixtures often require specialized installation, especially for large chandeliers and complex feature lighting.

What is involved:

• Site preparation and safety setup
• Fixture uncrating and inspection
• Installation and mounting — sometimes requiring rigging or scaffolding
• Electrical connection and testing
• Focusing and aiming — for adjustable fixtures
• Scene setting and control system programming
• Final walkthrough and handover

For large or complex installations, we recommend having a factory representative on site for the first few days to supervise installation and troubleshoot any issues. This adds cost but prevents installation mistakes that could damage the fixtures.

Factors that affect lead time

These are the variables that have the biggest impact on how long a custom lighting project takes:

1. Design complexity. A simple modified-standard fixture takes weeks. A one-of-a-kind sculptural chandelier takes months. Complexity is the single biggest driver of lead time.
2. Decision speed. How quickly the client reviews and approves designs, samples, and prototypes. Slow approvals are the #1 cause of delay.
3. Number of revisions. Each round of design revisions adds 1–2 weeks. Changing the design after prototype approval is especially costly and time-consuming.
4. Quantity. Larger quantities take longer to produce, but the per-unit time decreases due to economies of scale. 10 custom fixtures do not take 10x as long as 1.
5. Material availability. Special materials (exotic metals, custom glass, specialized finishes) can have long lead times. Standard materials are usually available immediately.
6. Certification requirements. If fixtures need SASO, ESMA, or other local certification, and they are not already certified, this adds 2–4 weeks.
7. Shipping method. Sea freight takes 4–6 weeks; air freight takes 1–2 weeks. The choice depends on schedule and budget.
8. Factory workload. Factories have peak and slow periods. Ordering during peak season (before major religious holidays or construction deadlines) can add time.
9. Site readiness. If the site is not ready for installation when the fixtures arrive, you are paying for storage and the project timeline slips anyway.

How to shorten the timeline

If you are working on a tight schedule, here are some strategies to reduce lead time without compromising quality:

• Start early. The earlier you engage a custom lighting partner, the more time you have. Bring us in during the design development phase, not when you are ready to order.
• Provide a complete brief. The more information you give us upfront, the fewer questions we have and the faster we can move.
• Limit design revisions. Try to get all stakeholders aligned before the design goes to prototyping. Major changes after prototype approval are very time-consuming.
• Parallel-path critical items. For large projects with multiple custom fixtures, we can start the most complex or time-consuming pieces first while simpler pieces are still being designed.
• Use standard components where possible. Custom does not mean every single part has to be bespoke. Using standard LED engines, drivers, and mounting hardware saves time and improves reliability.
• Pre-order long-lead materials. If we know we will need special glass or a custom finish, we can order those materials before the final design is 100% approved.
• Plan for certification early. If your project requires SASO or ESMA certification, let us know at the start. We can design with certification in mind and start the process early.

The cost of rushing

It is possible to speed up custom lighting production, but it comes at a price. Here is what rushing typically costs:

• Overtime and expedited production: 20–50% premium on production cost
• Air freight instead of sea freight: 3–5x the shipping cost
• Rush prototype: Can cut prototyping time in half, but adds 30–50% to prototype cost
• Risk of quality issues: When you rush, corners get cut. Sometimes it works, but sometimes you end up with problems that take longer to fix than the rush saved.

Typical project timelines

Here are realistic total timelines for different types of custom lighting projects, from initial brief to installation on site.

The key takeaway: start early. Custom lighting takes time, and the best way to avoid stress and rush charges is to plan for it from the beginning of the project. If you are an architect or interior designer working on a project that will need custom lighting, reach out to suppliers during design development, not when construction is already underway.
