Guangya Lighting Fair, June 2017. We brought the full solar street light range and a factory-side perspective: adjustable power, lithium or lead-acid battery choices, custom mounting brackets and voltage tweaks for different markets. Buyers asked practical questions about battery life, panel performance and IP ratings.

Nearly a decade later, the same questions appear in almost every OEM conversation. The answers have improved; the questions have not.

Question 1: Can You Adjust the Power?

Then and now, buyers want a model that fits a specific road rather than a catalogue slot. Adjustable power lets one platform cover 20W to 120W, which reduces tooling cost and simplifies spare parts.

Question 2: Which Battery?

In 2017 lead-acid was still common in some markets because it was cheap and familiar. Today LiFePO4 dominates, but the underlying question is unchanged: what does the pack cost over its life, not at the counter? A cheap battery with a short cycle life is the most expensive component in the lamp.

Question 3: Can You Change the Bracket?

Mounting is where OEM projects succeed or fail. A bracket that fits an existing pole avoids civil works; a bracket that does not turns a lamp swap into a construction job. Buyers ask for drawings early, and they should.

Question 4: What About Voltage and Certification?

Different markets have different requirements, from voltage labelling to certification scope. The practical answer is to agree the documentation pack before production, not after the container is loaded.

What Has Changed

Two things. Buyers now ask about spare parts before the first order, and they ask how a component change will be communicated later. Both questions come from experience: a private-label line is only valuable if it can be serviced for years.

How to Run an OEM Meeting

Bring three things: a target price band, a sample of the market you are selling into, and a list of the parts you expect to stock. With those, a supplier can propose a platform and a tooling plan in one session. Without them, the meeting becomes a catalogue review, and the buyer leaves with a brochure instead of a decision.

The Lesson

OEM is not a cosmetic exercise. It is a supply agreement with a product attached. Suppliers who treat it that way keep their customers through model changes; the rest restart the conversation every year.
