FAQ

Q Which LED brands do you support?

We work with major brands like Cree, Lumileds, Osram, Nichia and so on. Also with COB, SMD and high-power LEDs of all kinds.

Q I only need a small quantity at first. Is the optical design still free?

Yes, absolutely. Free design is a promise we make to every customer, big or small.

Q How long does it take from design to shipping?

If you provide the design drawings, we will spend approximately one week designing the experimental mold within 10 days, confirm the light spot characteristics, and produce the final mold in about 25 days. Once you receive the confirmed mold ready for production, the project can be completed through mass production in just 10-12 days.As a dedicated optical lens manufacturer with a 16-year Shenzhen factory, we keep tight control over every stage to ensure on-time delivery.

Q What is the minimum order quantity for custom lenses?

It depends on the mold size. Even if your volume is small, you still get free optical design. Just talk to us, and we’ll find a way.

Q What if my initial quantity is very small?

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

Q Why do mold costs vary so much between factories?

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 Is the optical design really free?

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

Q Can you quote without ready-made drawings?

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 How fast can I get a quote?

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

Q For outdoor lighting and LED street lighting projects, COB LED and high-power SMD LED are the most commonly used options

When selecting the right LED type, consider the following:
• Application (outdoor lighting, street lighting, industrial, decorative)
• Required brightness and uniformity
• Beam angle and LED lens compatibility
• Optical design and light distribution
• Thermal management and system reliability
• Environmental factors (IP rating, temperature, humidity)
For professional lighting projects, combining the right LED type with optimized optical solutions and LED modules is essential for long-term performance and cost efficiency. If you have any related questions, please feel free to contact us at any time!
