LED Strip Light RFQ: How to Get Comparable, Project-Ready Quotes

A quote for “24V COB LED strip, 3000K, 500 meters” can be fast and still be the wrong quote. It does not say whether the tape must fit a narrow groove, finish at an exact length, match an existing dimmer, or arrive as labelled assemblies. Those omissions do not disappear. They become supplier assumptions.

A useful LED strip RFQ defines the installed result, the product variant and the purchasing unit separately. That lets a buyer compare offers without discovering after sample approval that one price covers bare reels and another includes cutting, leads, packaging or a different power level.

This guide shows how to build that request around actual RH single-color COB models, when to ask about tunable-white COB, and what should remain conditional until the sample and quotation are confirmed.

1. Make the supplier quote a decision, not a product label

Start with one sentence explaining what must work: “Two concealed light lines per indoor display unit, no visible dots through the selected cover, fixed 3000K, accessible low-voltage connections.” Then attach the profile section and the length schedule. The supplier can now see which requirements are essential and which options may change.

Separate the RFQ into three columns: fixed requirements, proposed starting points and supplier confirmations. An 8mm maximum PCB width may be fixed. A 10W/m power level may be provisional. The permitted feed length, exact lumen output and driver pairing need confirmation. Treating all three as settled facts makes a polished RFQ less useful, not more precise.

2. Build the shortlist from the installation constraint

These catalog entries provide concrete starting points. They are indoor IP20 product families, not recommendations for wet areas. Verify the chosen CCT, output, assembly details and current availability in the quotation.

If a deeper concealed profile makes individual LED packages acceptable, include an SMD strip alternative in the same request. Compare the complete covered sample, not a bare COB reel against an uncovered SMD board. Read the COB versus SMD commercial selection guide when choosing which architecture to sample.

3. Quote finished pieces as well as total meters

Consider a hypothetical order for 60 display units, each needing two 900mm light lines. With a 50mm cutting interval, 900mm contains 18 segments. The installed tape quantity is straightforward:

But 108m is not necessarily the reel purchase quantity. If the selected variant is supplied on 5m reels and only whole 900mm pieces are used, each reel yields five pieces, with 500mm remaining. Producing 120 pieces requires 24 reels: 120m purchased, 108m installed and 12m of offcuts. This example excludes samples, spares and damaged pieces; some projects can reuse offcuts, others cannot.

Ask for two clearly separated options: full reels for local fabrication, and factory-prepared lengths if available. The second option needs a drawing, lead length, polarity, termination method, tolerances and packaging. Do not assume that cutting and assembly are included in a meter price or offered for every quantity.

For the 10W/m variant, the two 900mm lines represent a nominal 18W per display, or 0.75A at 24V before other system loads and losses. That is a load estimate, not a driver recommendation. The driver, wiring, controller and installation temperature still have to be checked.

4. Use a specification schedule the supplier can answer

Keep a supplier-response column in the RFQ. “Complies” is not enough where the requirement is provisional: the reply should name the offered value or identify a deviation.

A broad catalog CCT range does not make a fixed-white strip adjustable. Likewise, “dimmable” does not identify a compatible system. Put the driver/controller model and desired control behavior in the schedule. DOE distinguishes tunable white from dim-to-warm because they provide different control behavior; the RFQ should do the same.¹

5. Ask for evidence at the correct product level

For market access, ask what the document actually covers: the tape, a driver, a component or the assembled lighting system. A supplier’s general logo sheet is not a substitute for model identification and document scope. UL’s lighting guidance distinguishes product categories and their evaluation routes; it does not establish certification of any RH model mentioned here.²

For EU-bound products, list the requested RoHS documentation explicitly and have the responsible compliance team check applicability and current requirements. RoHS concerns restricted substances; it is not a brightness test, color-consistency guarantee or complete electrical-safety approval.³ Do not approve a purchase merely because a quote contains familiar certification acronyms.

For commercial comparisons, specify the named place and the edition of the agreed Incoterms rule. ICC explains why the place is central to interpreting the chosen rule.⁴ Keep freight, tax assumptions, payment terms and acceptance terms visible rather than expecting a three-letter shipping term to settle the whole transaction.

6. Approve a reference assembly, not just a bright sample

A useful pilot combines the selected tape with the real profile, cover, wiring and control equipment. Check physical fit, start-up, dimming if required, appearance at normal viewing angles, and the chosen light level after stable operation. Retain the approved assembly or a traceable reference, not just a phone photograph.

Record the sample identifier, datasheet revision, CCT/power variant, profile and diffuser codes, wiring layout and agreed acceptance criteria. Ask how a later production change will be communicated. For a phased order, retain enough information to distinguish a replacement driver problem from a changed tape variant.

This is where the RFQ becomes a purchasing control. If the supplier offers a different wattage, cut interval or color variant after sampling, it should be treated as a declared substitution with a review step, not silently placed under the same broad family name.

7. Compare quotes with a short exception list

Before comparing totals, mark every missing or substituted item. A practical comparison has four groups: tape, assembly/accessories, packaging/documentation, and freight or delivery costs. Then mark technical exceptions separately. A lower total is not equivalent if it changes the light level or leaves the terminations to the installer.

• Quantity: Are meters, reels and finished pieces reconciled?
• Variant: Is voltage, width, W/m and CCT explicit?
• Evidence: Do reports and samples match that variant?
• Scope: Are connectors, drivers, controllers, labels and spares included or excluded?
• Change control: Does the bulk order reference the approved sample and revision?

The aim is not to make every supplier offer the same design. It is to make differences deliberate and priced. RH can then be evaluated on a proposed product configuration rather than an incomplete request for the cheapest meter.

Buyer questions

What if I do not know the required lumens per meter?

Send the target surface, viewing conditions, profile geometry and desired result. Ask for an output recommendation and a sample plan. Label the output target as unresolved instead of inventing a number.

Can I ask for a 930mm strip?

Yes, but distinguish the desired lit length from what the selected tape permits. A 50mm interval gives 900mm below that target; a 4mm interval gives 928mm. Connection space, tolerances and unlit end gaps still need a drawing review.

Should samples and bulk quantities be on the same RFQ?

Yes, as separate stages. Ask for separate prices and lead times, and make bulk approval conditional on the agreed sample checks. An annual forecast is not the same as a committed order.
