Approve stability on the complete production-intent sample, not from a product photo or base weight alone. Test the lamp on the tables, linen and service route it will actually meet; record rocking, sliding, tipping behavior and handling points; then retain the signed sample as the repeat-order benchmark.
Why is stability a restaurant purchasing issue?
A cordless lamp sits close to glassware, plates and moving hands. The buyer therefore needs a repeatable approval method that connects the product to the real table environment. A lamp can feel steady on a clean test bench yet behave differently on a small bistro table, thick linen, a joint between two tables or a frequently moved outdoor setting.
What should the sample test include?
| Test area | What to do | Record |
|---|---|---|
| Table fit | Place the lamp on every intended table and linen combination. | Rocking, sliding, usable clearance. |
| Guest contact | Apply light contact from typical seated directions. | Movement, recovery and nearby-object risk. |
| Staff handling | Carry, place, collect and recharge the lamp in the normal route. | Grip points, hand clearance and drop risk. |
| Repeat control | Compare several samples with the approved unit. | Base contact, alignment and visible variation. |
How do you check the base and table contact?
- Set the lamp on a flat, clean surface and check all contact points.
- Repeat on the venue's smallest table and normal linen.
- Check whether the base rocks before the lamp is touched.
- Slide the lamp gently to understand friction and marking risk.
- Inspect the underside material, joints and edge contact.
- Repeat after a normal cleaning cycle.
Do not treat a larger or heavier base as automatic proof. Footprint, center of gravity, geometry and contact material all influence the result.
How should guest contact be simulated?
Place empty glasses and service items at realistic distances, then apply light contact from the directions guests are likely to reach. The purpose is not to create an arbitrary strength claim; it is to discover whether the chosen lamp, table and layout work together before rollout.
What should staff test during a closing shift?
- Where can the lamp be gripped without touching the diffuser or switch?
- Can several units be carried safely in the intended tray or trolley?
- Does the charging connector remain visible and accessible?
- Can staff identify units that need inspection?
- Does the lamp return to the same table position after cleaning?
How does battery configuration affect approval?
Battery capacity, cell choice and internal layout can change mass distribution. Approve the exact configuration intended for production. Runtime, charging time and battery claims must be verified for that configuration; they should not be borrowed from a visually similar model.
What belongs in the approval record?
- Model and sample revision.
- Photos on the intended tables.
- Base-contact and handling observations.
- Approved battery and charging definition.
- Finish and cleaning method.
- Packaging and transport orientation.
- Named approval owner and date.
- The retained physical control sample.
Frequently asked questions
Can a buyer approve stability from photos?
No. Stability depends on the complete sample, table surface and guest contact, so approval should use a physical sample.
Is a heavier lamp always more stable?
Not necessarily. Base footprint, center of gravity, geometry and contact material also influence the result.
Should the lamp be tested while charging?
Test the approved charging method separately and keep the guest-use stability check cable free.
What should be kept after sample approval?
Keep the signed sample, photos, revision record, packaging definition and agreed inspection points.
Does this checklist replace a formal safety test?
No. It is a buyer approval workflow and does not replace required laboratory testing or market-specific compliance evidence.
