When to Change Lamp Supplier, and How to Do It Without Losing a Season

Buyers change lamp suppliers for ordinary reasons: a finish that drifts between batches, a response time that slipped, a minimum that no longer fits, a price that stopped being competitive. The decision is usually correct. What goes wrong is the transition, because the replacement programme is live before it is proven and the old one has already been wound down.

Separate the real reasons from the annoyances

Some complaints are structural and some are irritations. A finish that changes between production runs is structural, because it breaks the visual consistency a shelf or a guest room depends on. A slow reply to one email is an irritation.

Structural reasons justify the cost of switching: inconsistent specification, documentation that cannot be produced for specific models, a minimum that no longer matches the order pattern, or a lead time that keeps moving after it was committed.

A Scorecard for Lighting Suppliers gives a way to score this consistently, and How to Evaluate a Lamp Supplier Before You Commit covers the evaluation sequence for the replacement.

Cost the switch before you decide

The visible cost is the new samples and the new tooling or packaging if the programme is private label. The invisible cost is the overlap: the period where you are running two suppliers, two sets of cartons, two documentation files and possibly two finishes on the same shelf.

There is also a cost to staying that is easy to undercount. A supplier whose lead time has slipped twice has already cost you the sales that did not happen, and those do not appear on any report.

Write both numbers down. If the switching cost is recoverable inside a season, the decision is easy; if it takes two years, the case needs to be stronger than an annoyance.

Run the overlap on purpose

The safest transition is a deliberate overlap: the new supplier is qualified and stocked while the old one is still supplying, and the old relationship is wound down only once the new stock is actually on the shelf or in the warehouse.

That means qualifying the replacement properly — sample round, documentation, a small first order — before reducing the incumbent's volume. The Sample Round: How to Order, Evaluate and Sign Off a Lamp Before Volume is the sequence to run.

Do not announce the change to the incumbent until the replacement is real. An incumbent who learns they are being replaced before you have stock will not prioritise your last orders.

Protect the specification during the handover

• Photograph and document the approved sample from the outgoing supplier, including finish, shade, cord, plug and switch.
• Send that record to the incoming supplier as the target specification, not a description of it.
• Approve a production sample from the new supplier against the same record before volume.
• Confirm the new models carry the listing documentation you need, at model level.

Plan the sell-through of the old stock

If the change is driven by a finish inconsistency, decide what happens to the stock that carries the old finish. Selling through quietly is often fine; mixing old and new finish on the same shelf is not.

For hospitality and contract buyers the rule is usually stricter: rooms should not contain two visibly different versions of the same lamp. In that case the old stock becomes attrition stock for back-of-house or is held for a different property.

Why Lamps Get Returned, and What the Product Design Can Do About It is a useful check on whether the problem being solved is actually a product problem rather than a supplier problem.

Give the incumbent a chance to fix a fixable problem

A supplier who has been good for three years and slipped for one quarter is often worth a direct conversation. Name the specific failure, ask what changed, and see whether the answer is credible and specific.

Vague reassurance means the problem is structural. A specific explanation with a date attached means it may be recoverable, and keeping a proven supplier is usually cheaper than qualifying a new one.

Where Anrotix fits

Anrotix holds 120V floor and table lamps in US stock from ten units with mixed SKUs, dispatched within one business day and typically delivered in three to seven business days, so a buyer qualifying a replacement can start with a small mixed order rather than a commitment.

Wholesale pricing is quoted by tier, and the model, finish and documentation set is the same whether the order is ten units or a programme. Send the models you are replacing and the quantities with an enquiry.

Frequently asked questions

When is changing lamp supplier clearly worth it?

When the problem is structural: inconsistent specification between batches, missing model-level documentation, a minimum that no longer fits, or committed lead times that keep moving.

Should I tell the current supplier I am switching?

Not until replacement stock is real. Announce early and the incumbent will not prioritise your remaining orders.

How do I stop the specification drifting during the switch?

Document the outgoing approved sample in detail — finish, shade, cord, plug, switch — and send that record, not a description, to the incoming supplier as the target.
