Every buyer now receives advice to diversify supply. The advice is sound and the execution is where programmes break, because two factories building to the same drawing rarely produce the same lamp.
What actually has to match
The drawing is the least of it. Finish, shade material, cord and switch specification, packaging structure and the certification scope all have to match, and each of them has a tolerance.
| Element | What to fix in writing | How to verify |
|---|---|---|
| Finish | Plating or coating process, not just colour name | Side-by-side panels under one light |
| Shade | Fabric weight, weave, seam construction | Physical sample against the reference |
| Electrical parts | Named switches, cords, sockets or approvals | Inspection against the parts list |
| Packaging | Structural drawing, board grade, artwork file | Drop test and carton check |
| Certification | Model listed on a valid certificate | File lookup before the first order |
Run a golden sample into both factories
The reference unit, signed and dated, is what both suppliers are measured against. Without it, every quality conversation becomes a comparison of two opinions, and the factory with the better photographs wins.
Split by model, not by percentage
Giving two factories the same model at fifty percent each maximises the risk of visible inconsistency. Assigning whole models to each factory, in a way the customer never sees side by side, keeps the assortment coherent and still removes the single-source dependency.
Budget for the learning curve
A new factory's first order takes longer, produces more samples and usually has one component that needs correction. Plan for it rather than discovering it in the middle of a season, and never launch a new source on a peak-season order.
Keep the second source warm
A qualified alternative that receives no orders for two years is no longer qualified. A small annual purchase keeps the relationship, the tooling and the certification current, and converts a contingency into a real option.
Frequently asked questions
Why diversify lamp sourcing
Diversification reduces single-origin risk from tariffs, capacity crunches, or disruption, and gives leverage in negotiation. A second qualified source also shortens the path if the first falters.
How many sources is enough
For most programmes, two qualified sources per critical model is enough to manage risk without doubling overhead. More sources add audit and quality cost that rarely pay back for slow movers.
Does a second source change the certification
A new factory building the same model must hold its own listing for that construction, or the model must be certified at the new site. Do not assume a certificate transfers; confirm the listing covers the actual production source before you ship.
