A customer asks whether one set will cover a patio. Another wants lights for a café terrace that stays open late. Your purchasing team needs to know how much stock to commit to—and when it can arrive.
These are the questions a useful wholesale specification should answer. A product photo can show the decorative effect, but choosing G40 solar string lights for your wholesale business also means comparing usable coverage, understanding charging and runtime, and agreeing on supply and support terms.
Use this guide to build a buying brief, evaluate samples, and move from a trial order to bulk purchasing. The Couleelight range provides three configurations to compare, with U.S. sample availability and standard orders starting as low as one carton of 12 sets.

Choose for the customer’s layout and evening routine
Start with two questions: Where will the lights go, and how will the customer use them? The answers are more useful than selecting the longest string or the highest bulb count by default.
| Customer or setting | Main buying priority | What to establish first |
|---|---|---|
| Home patios and gardens | A layout that fits the seating area and is straightforward to operate | Intended cable route, panel position, and clarity of installation instructions |
| Restaurant and café terraces | Decorative lighting that suits the evening service routine | Required operating hours, preferred light effect, and access to controls |
| Events and seasonal displays | A workable setup, charging, and storage plan | Charging opportunity before use, installation schedule, and packing arrangements |
These scenarios help you plan an assortment. Confirm the model’s installation instructions and outdoor-use limitations before recommending it for a particular site. For a café, for example, discuss decorative atmosphere separately from any task or safety lighting the venue needs.
For each customer segment, write a short buying brief: intended setting, measured route, desired nightly operating period, and available solar-panel location. This gives your sales team a consistent basis for recommending a configuration—and gives the supplier a clearer request to answer.
Compare 7 m, 12 m and 21 m G40 configurations
Couleelight offers three G40 solar LED globe string-light configurations:
| Configuration | Listed total length | How to use it in your assortment planning |
|---|---|---|
| 10 bulbs | 7 m | Compare against shorter decorative routes and customers seeking fewer light points. |
| 20 bulbs | 12 m | Evaluate when a customer’s layout calls for more length and more light points than the 10-bulb option. |
| 40 bulbs | 21 m | Evaluate for longer routes, with particular attention to supports and panel placement. |



Configuration illustrations for comparison. Confirm included contents, illuminated length, lead length and bulb spacing in the current SKU drawing.
Total length and illuminated length answer different questions. Total length helps describe the overall set; illuminated length tells the buyer where the bulbs begin and end. Request a dimensioned drawing showing both, together with lead length, bulb spacing, and connection points.
Do not derive bulb spacing by dividing total length by bulb count. That calculation would assume a cable layout that has not been confirmed. Bulb count alone also cannot tell you how brightly a finished space will be lit.
Ask customers to measure the planned cable route, including drapes and changes of direction. Then compare it with the model drawing. A 12 m route should not automatically be matched to a 12 m set: part of the listed length may be needed between the panel and the first bulb.
If a layout needs several runs, confirm whether they require separate sets and panel positions. Obtain model-specific instructions before offering end-to-end connection, extensions, or cutting to length.
For opening stock, let customer inquiries guide the configuration mix. If most inquiries concern compact patios, investigate those layouts first; if buyers are furnishing larger terraces, collect their measurements before choosing quantities. An equal split across all three configurations is a purchasing choice, not a requirement.
Separate solar charging from lighting runtime
A useful way to explain solar lighting is to separate energy collected during charging from energy used while the lights operate.
Shade, panel exposure, season, and weather affect the charging opportunity. Brightness, lighting mode, and operating duration affect energy use. A timer helps set the operating schedule; it does not establish that the control box has received a full charge.
For Couleelight, the stated runtime is up to 50 hours when the control box is fully charged, in steady-on mode at normal brightness. Ask which configurations the statement covers and which setting is defined as normal brightness when preparing your SKU-specific listing.
Treat this as a conditional maximum. One day of sunlight will not necessarily produce a full charge, and the figure should not be presented as a guaranteed result every night.
Couleelight’s remote supports brightness, mode, and timer adjustment. Request the current operating guide to confirm the available settings. During sample evaluation, assess the light effect your customers want alongside the operating period they need. Record charging conditions, mode, brightness setting, and elapsed operating time together so the observation is useful.
This also helps your team answer a common customer question: “How long will it run in my garden?” Start with the intended schedule and charging location, then use model-specific guidance and relevant sample observations to explain expectations.
Make the sample review useful to purchasing and sales
A good sample review should answer three questions: Does the set match the specification? Is the experience suitable for the customer? What needs clarification before ordering?
Couleelight’s current design features a black control box with orange corner guards. Match the supplied version to the product images and written specification, then work through the same checklist for every configuration you evaluate.
| Check | Practical sample-review task |
|---|---|
| Control box | Inspect the housing, controls, markings, and cable entry for visible defects. Check that the instructions explain operation clearly. |
| Light performance | Check that all bulbs illuminate. Observe visual consistency and the decorative effect at the documented settings in a representative location. |
| Remote operation | Try the documented brightness, mode, and timer functions. Record the distance and conditions used. |
| Connections and cable layout | Compare the assembly with the dimensioned drawing. Inspect visible fit and finish, and review instructions for positioning and securing connections. |
| Packaging and contents | Compare contents with the packing list. Assess packing protection, SKU identification, instructions, and suitability for your retail presentation. |


Keep a simple review record: model, date, conditions, observation, and follow-up question. For example, “timer function needs clarification in the instructions” gives the supplier something specific to resolve before the order.
Use the sample to approve appearance and operation, and request supporting specifications for claims that require more evidence, such as a protection rating or material grade. Visual inspection alone cannot establish those properties.
Retain the approved sample and specification as references for bulk supply. If your business requires a pre-shipment inspection, agree on its scope and acceptance criteria before production or order preparation begins.
Use a small opening order to learn what to stock next
Couleelight can send samples from its U.S. warehouse, subject to availability. The warehouse also supports retail supply; bulk orders ship directly from the factory. Confirm sample stock, charges, and shipping arrangements when you inquire.
Standard orders start as low as one carton containing 12 sets. Ask which configurations are available and whether mixed cartons are possible. OEM and private-label minimums are quoted separately.
A practical purchasing path is:
- Evaluate samples: resolve questions about coverage, controls, packaging, and instructions.
- Approve the specification: record the exact configuration and supplied version.
- Place a trial order: choose a quantity that fits your budget and the stock available.
- Review the response: track requested lengths, customer questions, actual orders, and support needs before planning replenishment.
Set the review criteria before the trial. For example, track inquiries and orders by configuration, and note recurring questions about panel placement or timer operation. These observations can inform both your next order and your product-page content.
Compare the landed cost per set, too. Request carton dimensions and shipping weight, then add freight and applicable import or handling costs to the product cost using a consistent basis. A lower unit quotation does not necessarily produce a lower delivered cost. A smaller trial reduces the initial quantity committed, while leaving sales and profitability to be evaluated through actual trading.
Plan bulk supply around the required receipt date
Small quantities may be available from stock, subject to actual inventory. For bulk orders, Couleelight’s production or preparation lead time is generally 15 working days, excluding transportation. Reconfirm the timing for your configuration, quantity, and any customization.
Work backward from when you need stock available for sale. Allow separately for sample approval, artwork approval where applicable, production or preparation, freight, customs clearance, and final delivery.
Before committing, request a written quotation covering:
- Model reference, configuration, quantity, and approved product version.
- Stock availability, production or preparation timing, and its starting point.
- Shipping origin, transport method, delivery terms, payment terms, and freight estimate.
- Packaging, labeling, inspection arrangements, and included documentation.
Couleelight supports OEM/private label. Describe the changes you want and ask what is available, including branding, packaging, and instructions. Confirm scope, minimum quantity, fees, approval steps, and lead time before applying standard-order assumptions to a customized order.
For import purchasing, request the applicable FCC, CE, and RoHS documentation for the exact model and destination market. Have the responsible compliance team check the documents against the product being ordered and your sales-channel requirements. The European Commission’s CE guidance explains the role of manufacturer responsibility and supporting documentation; a logo on an image is not enough for a purchasing review. European Commission guidance on CE marking.
Agree on after-sales support before the order
Couleelight provides a 12-month whole-product warranty and has spare parts available. Request the written terms so your purchasing and service teams understand how support will work.
Clarify when coverage starts, what it covers, what evidence a claim needs, the available remedies, and responsibility for shipping costs. Ask which spare parts are available for your model, how compatibility is identified, and what ordering and supply arrangements apply.
Keep the approved specification, order reference, instructions, and supplier contact details together. This gives your team a useful starting point when a customer needs help and avoids having to reconstruct the original purchase later.
Frequently asked questions
Which configuration should I stock first?
Start with your customers’ layouts and inquiries. Compare the 7 m / 10-bulb, 12 m / 20-bulb, and 21 m / 40-bulb options using a dimensioned drawing, then use trial-order results to guide replenishment.
What does the up-to-50-hour runtime mean?
Couleelight states up to 50 hours when the control box is fully charged, in steady-on mode at normal brightness. Confirm the applicable SKU and brightness definition. Actual charging conditions and settings matter; the figure is not a daily runtime guarantee.
Can I order one carton with my own branding?
The standard minimum is as low as one carton of 12 sets. Private-label scope, minimum quantity, pricing, and lead time need a separate quotation.
Can I receive samples from the U.S.?
Samples can be sent from Couleelight’s U.S. warehouse, subject to stock. Confirm costs and shipping arrangements. Bulk orders ship directly from the factory.
