SHENGQI LIGHTING / FLASHLIGHT SELECTION
Start with the job.
Build the right lighting range.
Choosing a flashlight for your product range starts with how people will use it: the distance they need to see, the time they spend working, and the way they carry and recharge their light. For brands, importers and distributors, those details shape a useful shortlist. This guide from Shengqi Lighting helps procurement teams compare flashlight options, review selected models and prepare an OEM/ODM brief. Use it to connect beam performance, power supply and durability requirements with the samples and specifications you need to evaluate.
- Match the beam to the working distance.
- Compare useful output throughout the task.
- Confirm the sample configuration before ordering.
YOUR SHORTLIST STARTS HERE
Three decisions before a model number
Task & beam
Close inspection, general movement or distant observation?
Power & duration
Short checks or extended use between charging opportunities?
Carry & conditions
Pocket, belt or equipment bag? Dry indoor work or outdoor exposure?
Choose a flashlight around the job
Describe one typical use before comparing products. A light used for occasional checks has different priorities from one carried through an entire shift. Define working distance, use frequency, access to power and carrying method. Then separate essential requirements from optional features.
| Buying question | Specifications to compare | Effect on use |
|---|---|---|
| What needs to be visible? | Beam pattern, candela and beam distance | Balances central reach with coverage around the task. |
| How often and how long? | Output by mode, runtime curves and thermal step-down | Shows whether useful illumination lasts through the intended task. |
| Where can users replenish power? | Approved battery options, charging input and replacement method | Determines the charging routine and need for spare batteries. |
| How will it be carried? | Dimensions, weight with battery, grip and attachment options | Affects comfort, storage and access while wearing work clothing. |

Compare the specifications that matter
Read flashlight specifications together. A headline number becomes useful when you know the operating mode, battery configuration and test conditions behind it.
Beam pattern & intensity
Lumens describe total light output; candela describes intensity in a direction. Compare the central hotspot and surrounding spill at the intended working distance. A stated test beam distance does not establish how far a user can identify an object in real conditions.
Peak & sustained output
Maximum brightness may be available only briefly before output steps down. Request an output-over-time curve and assess illumination after warm-up. For extended work, compare the level maintained during the task as well as the initial peak.
Runtime & operating modes
Match each runtime figure to its brightness setting and test endpoint. The longest runtime may belong to a low mode, and a runtime figure does not promise constant brightness. Compare the modes users will actually select.
Battery & charging
Confirm the approved battery type, whether users can replace it, and the specified charging input. Rechargeability and replaceability are separate features. A USB-C connector alone does not confirm USB Power Delivery or fast charging; verify the supported power profile, cable and charger.
Water resistance, impact & test conditions
Check the exact IP rating and water-test conditions, including closure of any port covers. An IP rating alone does not establish diving suitability. For impact claims, request the drop height, test surface and acceptance criteria. Evaluate evidence for the specific model and configuration you plan to buy.
Explore selected flashlight models
Use these models as starting points for comparison. Review the individual product details, then request the current specification for your intended configuration.
L88
Dual 21700 battery configuration
A long-body rechargeable model with a power indicator. Include it when comparing larger handheld formats, then assess beam performance, carrying space and the charging routine against your brief.
L80
18650 rechargeable battery configuration
A long-body flashlight with a power indicator. For a distance-focused shortlist, compare its beam with the surrounding coverage you need, and check handling with the clothing or gloves used on the job.
CW101
21700 battery with multiple output modes
A rechargeable aluminum-body option with high, medium and low settings. Compare the modes needed for routine outdoor tasks, and request runtime information for the setting your customers will use most.
Refine your flashlight requirements
Everyday carry priorities
When pocket space and frequent access matter, start with dimensions, weight and carry attachments. Then check whether the available beam and controls suit daily use.

From a product brief to an OEM/ODM discussion
An existing model provides a starting point for discussing branding and packaging. A functional change needs a review of the affected optics, electronics or structure. A new product concept requires a broader development brief.
Shengqi Lighting offers design and development services for portable lighting projects. Feasibility, project scope and commercial terms depend on assessment of the specific requirements.
OEM/ODM design and developmentInclude in your brief
- Intended use and target market
- Planned quantity and key performance needs
- Branding and packaging requirements
- Target sample and launch timing
Verify the sample before planning the order
Use this buyer-side checklist to organize flashlight sourcing. Agree the relevant documents and acceptance criteria with the supplier for your project.
- Sample and specification: match the model, battery, controls, accessories and finish to a dated specification.
- Performance evidence: record the operating mode, battery and conditions used for output and runtime testing.
- Packaging and instructions: check artwork, included items, operating guidance and charging information.
- Market documentation: request compliance records applicable to the exact model, configuration and destination market.
- Approval record: document the accepted sample, agreed production requirements and any subsequent changes.
Flashlight selection FAQs
How do I start choosing a flashlight?
Write down the task, working distance, expected use duration and carrying method. Add the charging conditions and target market. These details help narrow the range before comparing individual model specifications.
Should I compare lumens first?
Use lumens alongside beam shape, intensity and sustained output. For distant observation, inspect the hotspot and reach. For close work, assess coverage and glare. More total light does not automatically provide a better beam for the task.
How do rechargeable and replaceable batteries compare?
A flashlight can offer both. Rechargeability describes replenishing the battery; replaceability describes removing and exchanging it. Compare access to charging, approved replacement cells and the user's need to resume work without waiting for a recharge.
What affects actual runtime?
Mode selection, battery condition, temperature and output regulation affect runtime. Frequent high-output use can produce a different result from a low-mode test. Ask for the test conditions and an output curve for the relevant setting.
What information is needed for an OEM/ODM discussion?
Share the use case, target market, planned quantity, key performance requirements, packaging and timing. Identify whether you want branding on an existing model, functional changes or a new design so the team can assess the appropriate scope.
What should I prepare before requesting models and a quotation?
Provide your requirements and any shortlisted model numbers. Specify quantity, destination, battery and accessory preferences, and branding needs. List unresolved points clearly so the proposed configuration and quotation can be reviewed on the same basis.
PLAN YOUR NEXT PRODUCT DISCUSSION
Turn your requirements into a focused shortlist
Tell Shengqi Lighting where the flashlight will be used, your target market, planned quantity and essential performance needs. Include any preferred models and packaging requirements so our team can discuss suitable options and the next evaluation steps.
