A buyer searching for Table Lamp is usually trying to stop a bad substitute. A luminaire or lamp is specified by light output, color, the driver, and the environment around the optic. The notes below are selection criteria for a Table Lamp. They are not a catalog promise. Confirm every rating on the current datasheet, drawing, or test report for the revision you will receive.
What has to be true of Table Lamp
A luminaire or lamp is specified by light output, color, the driver, and the environment around the optic. For a Table Lamp, start from the duty, then the interface to the rest of the machine or the room, then the document that proves the claim. A lower price that leaves one of those blank is a different product.
Table Lamp is easy to confuse with Track Rail. If the quote could be read as either, add the line that separates them: the rating, the fitment, or the standard named below. Link the drawing number to that line so receiving inspection can reject the wrong one.
Numbers that change the quote
| Line | What to write for Table Lamp |
|---|---|
| Lifetime | The hour figure and the lumen maintenance it refers to, such as L70. |
| Lumens and candela | Delivered light, not only the LED chip claim. |
| Color | Correlated color temperature and color rendering. |
| Driver | Current or power, dimming method, and where the driver sits. |
| Optics and mounting | Beam angle, and ceiling, wall, pole, or high bay. |
| Environment | IP code, ambient, and whether the fitting is indoors only. |
How to compare two offers
Lay both quotes for Table Lamp on one sheet and line up lifetime, lumens and candela, and color. If a cell is empty, the offer is not finished. Ask for the missing line in writing. When those match, the honest difference is lead time, the test evidence, and who carries the warranty. Do not average a fully specified Table Lamp with a cheaper line that omitted lifetime.
Documents worth having before the deposit
Ask for a photometric file if the lighting layout depends on it. The file should name Table Lamp and the revision, not only the supplier’s homepage. A factory quality certificate such as ISO 9001 can sit beside that file. It does not replace it.
Failures that show up after delivery
- Pairing a lamp with a dimmer the driver does not support.
- Using an indoor fitting outside because the photo was taken at dusk.
- Buying watts instead of lumens.
On a Table Lamp, the expensive version of the first mistake is discovering it after the goods are in the crate. Put the rejection condition in the purchase order while the supplier can still restate the offer.
A worked RFQ line
Use this shape, then replace the brackets with your duty: “Table Lamp — State lumens, color temperature, driver type, beam, IP code, and ambient.” That sentence is a template, not a rating of any brand. If a supplier’s datasheet uses different units, convert them onto this sheet so the next offer can be compared.
Where words like waterproof / IP65 belong
Searches often add a constraint to Table Lamp: waterproof / IP65, or outdoor. Keep those on this page. IP65 in IEC 60529 means dust-tight and protected against water jets. Write that code if hoses are the real exposure. The word waterproof alone does not name a test. Outdoor means UV, temperature cycle, and corrosion, not only a gasket. Name the climate and the years the gasket is expected to last. If you need a third constraint, add it as another line on the same drawing. A second URL that only swaps the adjective does not give a buyer a second fact.

Questions buyers actually ask
What should an RFQ for Table Lamp include?
State lumens, color temperature, driver type, beam, IP code, and ambient.
Is a cheaper Table Lamp the same part?
Only if lifetime, lumens and candela, and the documents match. A missing line is a different offer.
Do waterproof, OEM, or IP words need their own page?
No. For Table Lamp they are extra lines on this specification. Ask for the test or the drawing that gives the word a value.
