To receive a reliable LED tube light quotation, you should send both commercial requirements and technical specifications. The most important details are tube size, power, input voltage, luminous flux, CCT, CRI, wiring type, driver type, certification requirement, installation environment, order quantity, packing needs, and delivery schedule.
Basic RFQ Information Buyers Should Send
What basic information is required for an LED tube light quotation?
The basic information should include product type, tube length, wattage, input voltage, color temperature, quantity, and target application. These details allow the supplier to identify whether you need a T8 LED tube, T5 LED tube, integrated tube fixture, or a special retrofit solution.
For example, a clear request would state: T8 LED tube, 1200 mm, 18 W, 220 to 240 V AC, 4000 K, clear cover, single-end input, 5,000 pieces for office lighting. This is much more useful than only asking for “LED tube price.”
Why is the installation location important for quotation?
The installation location affects the tube structure, safety rating, optical design, and maintenance plan. A tube used in an office ceiling grid may not need the same protection as a tube used in a parking area, cold room, warehouse aisle, or damp industrial space.
Suppliers may need to check ambient temperature, dust exposure, humidity, fixture enclosure type, ventilation, mounting height, and maintenance access. These conditions influence material selection, driver design, IP rating, thermal performance, and expected lifetime.
Should buyers send photos or drawings of the existing fixture?
Yes, photos or drawings are very useful when the LED tube will replace fluorescent lamps in existing fixtures. They help confirm lamp holder type, ballast condition, wiring space, reflector design, and whether the installation uses single-ended or double-ended power input.
Photos can also reveal hidden problems such as enclosed fixtures, narrow housings, damaged sockets, special mounting clips, or non-standard lamp spacing. This reduces the risk of quoting a tube that fits the specification sheet but fails during installation.
| Information to Send | Why It Matters | Example |
|---|---|---|
| Tube type and size | Confirms mechanical fit and product family | T8, 1200 mm, G13 base |
| Wattage and lumen target | Controls brightness, energy use, and price level | 18 W, 2,000 lm |
| Input voltage | Confirms driver design and electrical safety | 100 to 277 V AC or 220 to 240 V AC |
| CCT and CRI | Controls visual comfort and color rendering | 4000 K, CRI 80 |
| Wiring method | Prevents installation mismatch | Single-end input or double-end input |
| Certification need | Controls market access and compliance cost | CE, RoHS, ETL, DLC, or project-specific standard |
Product Selection and Specification Questions
How should buyers specify wattage and lumen output?
Buyers should specify both wattage and target lumen output whenever possible. Wattage shows power consumption, while lumen output shows usable brightness.
Two LED tubes with the same wattage can produce different lumen output because of LED efficiency, diffuser loss, thermal design, and driver efficiency. If the project is replacing fluorescent tubes, provide the old lamp type, wattage, mounting height, and desired brightness level. For lighting design projects, share the lux requirement or photometric plan if available.
What CCT, CRI, and SDCM information should be sent?
You should send the required CCT, CRI, and color consistency requirement if visual appearance matters. CCT means correlated color temperature and is commonly specified as 3000 K, 4000 K, 5000 K, or 6500 K.
CRI describes how accurately colors appear under the light. CRI 80 is common for general commercial lighting, while CRI 90 may be needed for retail, inspection, or display areas. SDCM describes color variation between lamps. A lower SDCM value gives better color consistency across large installations.
Should buyers specify beam angle and diffuser type?
Yes, beam angle and diffuser type should be specified when light distribution or glare control matters. LED tube covers are often clear, frosted, striped, or milky, and each option changes brightness, glare, and visual comfort.
A clear cover can provide higher output but may show visible LED dots. A frosted cover usually gives smoother light but may reduce lumen output slightly. For warehouses, shelves, schools, offices, and retail aisles, the beam angle affects uniformity and shadows.
How does tube housing material affect quotation?
Housing material affects heat dissipation, electrical safety, weight, durability, and cost. Common LED tube structures include glass tube, aluminum plus PC cover, full PC tube, and nano-plastic tube.
Glass tubes may offer good optical clarity and cost efficiency. Aluminum bodies can improve thermal management. Full PC tubes are often preferred where impact resistance or safety concerns matter. If the project has IK rating, food area, transport vibration, or breakage risk requirements, mention them before quotation.
Field Experience Note: When replacing fluorescent tubes, do not rely only on lamp length and wattage. Check the fixture wiring and ballast condition before finalizing the RFQ. Many quotation errors happen because the buyer requests a “direct replacement” tube, but the site actually requires ballast bypass wiring, starter removal, or a different input method.
Electrical, Driver, and Dimming Details
What voltage and current information should buyers provide?
Buyers should provide the input voltage range and the electrical system used in the project country. LED tube drivers are designed for specific voltage ranges such as 100 to 240 V AC, 100 to 277 V AC, or 220 to 240 V AC.
Current is usually calculated from wattage and voltage, but it still matters for circuit loading, breaker sizing, and large project planning. If thousands of tubes are installed on multiple circuits, current, power factor, and inrush current can affect electrical design.
Do buyers need to confirm ballast compatibility?
Yes, ballast compatibility must be confirmed if the LED tube will be installed into existing fluorescent fixtures without rewiring. Some LED tubes are ballast compatible, while others require ballast bypass wiring.
Ballast-compatible tubes can reduce installation labor, but compatibility depends on the ballast model, ballast age, input voltage, and local electrical code. Ballast bypass tubes may improve long-term reliability by removing old ballast failure points, but they require correct rewiring and labeling.
Should the RFQ state single-end or double-end input?
Yes, the RFQ should clearly state whether the tube requires single-end input or double-end input. This affects internal wiring, lamp holder safety, installation instructions, and inspection requirements.
Single-end input means live and neutral connect to one end of the tube. Double-end input means live and neutral connect to opposite ends. Mixing the wrong tube with the wrong fixture wiring can create safety risks, installation delays, or product failure.
What dimming information is needed for LED tube lights?
You should state whether dimming is required and identify the dimming method. Common dimming methods include 0 to 10 V, triac dimming, DALI, or sensor-based control, although not every LED tube design supports every method.
Dimming affects driver selection, minimum load behavior, flicker performance, compatibility testing, and price. If the project uses a lighting control system, send the controller model, dimmer type, wiring diagram, and expected dimming range.
Installation Environment, Safety, and Compliance
When should buyers specify IP rating or IK rating?
Buyers should specify IP rating when the tube may face dust, moisture, spraying water, or damp operating conditions. IP rating describes protection against solids and liquids.
For dry indoor offices, a high IP rating may not be necessary. For parking areas, transit stations, food processing zones, cold storage, or semi-outdoor corridors, IP rating can become important. IK rating should be discussed when impact resistance is required, such as in public areas, industrial spaces, or sports facilities.
What operating temperature details are important?
Operating temperature should be provided when the project is in hot, cold, enclosed, or poorly ventilated spaces. LED tube lifetime depends strongly on driver temperature and LED junction temperature.
Cold storage may require special driver startup performance. High-temperature factories or enclosed fixtures may require lower wattage, better heat dissipation, or a different housing material. If ambient temperature is not confirmed, the quote may not reflect the real reliability risk.
What certifications or test reports should be requested?
Buyers should request certifications and test reports based on the target market and project requirements. Common items may include CE, RoHS, ETL, UL, DLC, EMC testing, photometric testing, LM-79 data, LM-80 data, or TM-21 lifetime projection.
Not every project needs every document. A private commercial retrofit may require different evidence than a government tender or utility rebate program. The RFQ should state whether certification marks, test reports, safety files, or customs documents are required before shipment.
Technical Factors to Check Before Sending RFQ
The following checklist helps buyers prepare a more complete RFQ before requesting price. It also helps suppliers avoid quoting a standard LED tube when the project actually needs a special driver, rating, package, or installation method.
| Technical Factor | What to Confirm | Quotation Impact |
|---|---|---|
| Mechanical fit | Tube length, diameter, base type, fixture space | Prevents fitment issues and accessory changes |
| Electrical input | Voltage range, frequency, wiring method | Controls driver design and safety compliance |
| Lighting performance | Wattage, lumen output, efficacy, beam angle | Controls energy use, brightness, and lighting result |
| Visual quality | CCT, CRI, SDCM, diffuser type | Controls color appearance and consistency |
| Control system | Dimming method, sensor need, controller model | Controls driver compatibility and testing work |
| Environment | IP rating, IK rating, temperature, humidity | Controls material choice and reliability risk |
| Compliance | Target market, required standards, test reports | Controls documentation, certification cost, and lead time |
| Commercial terms | Quantity, packing, label, delivery schedule | Controls unit price, production planning, and logistics |
Procurement, Packaging, and Project Delivery Questions
How does order quantity affect LED tube light quotation?
Order quantity affects unit price, production planning, packaging method, and lead time. A sample order, trial batch, project order, and annual forecast may each require different pricing logic.
For custom CCT, private label packaging, special certification, or non-standard wiring, the supplier may need to check MOQ before quoting. If the project will be delivered in phases, provide the expected shipment schedule instead of only the total quantity.
What packaging and labeling details should buyers send?
Buyers should send packaging, labeling, barcode, manual, and carton marking requirements if they are important for the project. Standard neutral packaging may not meet retail, OEM, warehouse, or project distribution needs.
Private label boxes, country-specific warning labels, installation diagrams, energy labels, and pallet requirements can affect cost and lead time. For fragile tube types, packaging design also affects transport damage risk.
Should buyers send a target price?
A target price is useful if it is linked to a realistic specification and order quantity. It helps the supplier recommend a suitable configuration instead of over-specifying or under-specifying the product.
However, target price alone is not enough. A low target price without lumen output, certification, driver quality, or warranty expectations can lead to wrong product comparison. For fair evaluation, compare quotations using the same technical baseline.
What is the best way to compare LED tube light quotations?
The best way is to compare quotations by specification, not only by unit price. Check wattage, lumen output, driver type, housing material, power factor, CCT tolerance, certification status, warranty terms, packaging, and delivery conditions.
A lower price may be reasonable if the specification is simpler. It may also indicate missing certification, lower lumen output, weaker packaging, or a shorter warranty basis. Ask for a technical datasheet and test data when the quotation will be used for project approval.
Common Misunderstandings That Delay Accurate Quotations
| Misunderstanding | Why It Creates Risk | Better Practice |
|---|---|---|
| All 1200 mm tubes are interchangeable | Base type, wiring, driver, and fixture space may differ | Send fixture photos and wiring information |
| Wattage alone defines brightness | Efficacy and diffuser design change lumen output | Specify both wattage and target lumens |
| Any LED tube works with existing ballast | Ballast compatibility depends on model and condition | Confirm ballast type or request bypass wiring |
| Certification can be added after shipment | Some certifications require design, testing, and documentation before production | State market requirements during RFQ |
| Packaging has little effect on price | Private label, barcode, manual, and pallet rules add cost | Send packaging files and logistics requirements early |
