Every custom LED lens project starts the same way. You have a lighting idea, but the standard lenses on the market don’t fit your needs perfectly — or they cost too much.

That leaves you with one clear path: custom LED lenses.

At Sunshineopto, we help customers walk this path every day.

As an optical lens manufacturer based in Shenzhen for 16 years, we’ve completed over 3,000 custom mold projects and offer free optical design from day one.

This article takes you through the very first stage of customization: from sending your requirements to receiving a clear, transparent quote.

You’ll learn what to prepare, how our factory evaluates your project, and what key details a trustworthy quote should include.

Step 1: Tell Us What You Need — Project Evaluation

Think of us as your optics tailor. Before we cut the fabric, we need your measurements.

The more details you share, the faster and more accurate your quote will be.

Here’s the key information that helps us understand your project:

LED model or brand. Are you using Cree, Lumileds, Osram, or Nichia? Or another brand’s COB or SMD? The LED’s light pattern and physical size directly affect how we design the lens.

Desired beam angle. A narrow 15° for spotlights? A wide 60° for floodlights? Or an asymmetric beam for wall washing?

Size and shape limits. What’s the maximum outer diameter and height for the lens in your fixture? Round, square, or a special shape? A simple sketch or 3D file helps enormously.

Estimated quantity. Just a rough number so we can pick the best production method. Even if you only need a few hundred pieces, we’ve got you covered.

Special requirements. Any material preference? Need UV resistance? High temperature tolerance? Built-in mounting clips or brackets?

Send us this information, and our engineers start the project evaluation right away.

If you’re not a technical expert, don’t worry — simply share your general needs, and we’ll provide a one-stop service to solve the problem for you.

With 16 years of hands-on experience, we can spot potential issues early and discuss adjustments with you. Good communication at this stage can save weeks of rework later on.

We promise to reply within 24 hours. If something isn’t clear, we’ll ask. You’ll never be left waiting.

Step 2: Receiving Your Quote — Quotation Confirmation

Once the technical plan is clear, we prepare your quote.

No hidden fees — just a straightforward document that includes:

Mold cost. A precision optical mold goes through many steps — roughing, heat treatment, mirror polishing, texture etching, and more. The number of cavities also affects the cost: 1+1, 1+2, 1+4, or more. More cavities mean higher output.

Unit price per lens. This depends on the material, molding cycle time, and order quantity. Larger volumes bring the per-piece cost down.

Estimated lead time. How long from design to first samples? How long from sample approval to mass production? (Need it faster? We’ll go all out for your project.)

Free design. Yes, really free. We provide free optical design for your LED project. This isn’t a bait-and-switch — it’s our commitment, saving you real R&D money before you even place an order.

All costs are clearly listed. Take your time, and ask as many questions as you like. We’re online 24/7, so you’ll get a fast reply no matter your time zone.

What Makes a Good Quote?

Not all quotes are equal. When comparing offers, look for these points:

Itemized costs. Mold cost, unit price, lead time — each listed separately.

Clear material specs. Is it PC or PMMA? What IP rating?

Clear mold ownership. The mold belongs to you. At Sunshineopto, always.

No forced large orders. A good factory works with your starting quantity. We grow with you.

Our quotes check every box. As a 16-year Shenzhen factory with 3,000+ completed mold projects, we understand both startup runs and large-scale production.

FAQ

Q: How fast can I get a quote?

A: We respond within 24 hours. Once requirements are clear, a full quote usually takes 1–2 working days.

Q: Can you quote without ready-made drawings?

A: Absolutely. A sketch, a reference photo, or a few key parameters (LED model, beam angle, size) is enough. We’ll fill in the rest.

Q: Is the optical design really free?

A: Yes, completely free. Free optical design and free LED circuit design are our promise to every customer, regardless of order size.

Q: Why do mold costs vary so much between factories?

A: The difference lies in steel quality, precision, and mold life. High-precision optical molds use top-grade steel and require mirror polishing — the upfront cost is higher, but they last longer and produce better lenses. Cheap molds often cost more per piece in the long run.

Q: What if my initial quantity is very small?

A: No problem. We tailor the production plan to your volume. Even tiny orders get the same free design support.
