Sensor Switch LED Corn Bulb Suppliers and Manufacturers

Sensor Switch LED Corn Bulb Supplier Concentration and Factory Types

Suppliers in this category fall into clearly identifiable types: manufacturers and factories that produce LED bulbs in-house, trading companies that consolidate output from multiple plants, and group corporations that combine both roles. On the current supplier page, all three company types appear, so buyers should not assume a single structure. The product lines overlap significantly: main products listed include LED bulbs, corn bulbs, panel lights, tube lights, flood lights, street lights, solar lights, filament lamps and energy saving bulbs, while other suppliers focus more narrowly on smart bulbs and motion sensor products. A sensor switch corn bulb typically combines a corn-style LED array with a radar or PIR motion detection module, so suppliers with a documented motion sensor bulb range are often better positioned than generalist lamp traders.

Regional concentration matters when shortlisting. One supplier location given as a high-confidence fact is Zhejiang, China, and another supplier is listed in Anhui, China, so buyers can treat both provinces as documented sourcing points for this page. Zhejiang's cluster context supports LED lighting supply chains, while the Anhui entry is a trading company whose range extends into alarms, doorbells and cable accessories, indicating broader electrical hardware coverage rather than pure lighting focus. Where no cluster is documented, buyers should map supplier locations from listing data, request factory addresses, and check whether the claimed site matches the registered business scope before investing in samples.

How to Verify Sensor Switch LED Corn Bulb Suppliers

Verification should start with third-party signals shown on the supplier page. At least one supplier on this page carries ISO 9001 system certification, another lists both ISO 9000 and ISO 9001, and one is marked as verified through CTI. These are meaningful starting points, but they are page-level claims: ask the supplier for the current certificate number, issuing body and validity period, and check the certificate against the certification body's public database. Note that one Anhui-based trading company lists QC 080000 and HACCP certifications, which are unusual for lighting and should prompt a direct question about which entity and production scope the certificates actually cover.

Company type is the second verification axis. A listing that says Trading Company, Manufacturer/Factory or Group Corporation tells you who you are negotiating with, but not who makes the goods. Request the production entity's full legal name, a business license copy and, where possible, a live video walkthrough of the SMT and assembly lines that would handle sensor modules. Research and development capability labels also help: this page shows suppliers offering OEM, ODM and own-brand arrangements, so ask which of these they genuinely support for sensor corn bulbs, since retrofitting a motion module onto a corn bulb design requires firmware or radar-tuning capability that a pure reseller cannot provide. Finally, confirm the certified scope matches the exported product, not just a sister product line.

What to Compare Across Sensor Switch LED Corn Bulb Suppliers

Use the attributes actually displayed, and never assume every supplier shows the same fields. Response time is directly comparable here: one supplier lists an average response time of about 7.8 hours, another about 12.3 hours, and a third about 5.4 hours, which matters when you are iterating on sensor sensitivity questions across time zones. Lead time data on this page diverges sharply, with one supplier showing roughly 23 days and another showing roughly 150 days, a gap large enough to determine whether a supplier is viable for replenishment orders at all. Ask for written lead times against your specific order size, since listing figures may reflect sample or small-batch conditions.

Compare product depth alongside the commercial fields. One supplier's lineup spans corn bulbs from 5W to 35W in E14, E27 and B22 bases, 220V input, PF above 0.5, CRI above 80, around 90lm/W efficiency and a stated 30,000-hour life, while a motion sensor specialist lists an A60 sensor bulb in 5W to 12W with 630lm, Ra above 80, a 270-degree beam angle and a two-year warranty. Establishment year, escrow availability and location should also be captured in your comparison sheet where displayed. Build the sheet with columns for company type, main products, certifications, response time, lead time, MOQ and capacity labels, and leave blanks where a supplier publishes nothing rather than guessing.

Common Sensor Switch LED Corn Bulb Sourcing Risks

The largest risk is conflating a plain corn bulb with a sensor-equipped version. Corn bulb listings on this page include detailed electrical specs, but the sensor functionality appears mainly in separate motion sensor bulb listings, and one supplier's radar motion sensor bulb is listed under a trading company whose main products emphasize alarms, doorbells and cable accessories. That combination is not disqualifying, but it means the sensor module may be sourced from elsewhere, adding a hidden second supply chain. Ask which factory produces the driver, which produces the radar or PIR module, and who is accountable if the sensor false-triggers in an installation with moving air or pets.

Specification drift is the second risk. Published attributes such as PF ranges of 0.5 to 0.9, Ra above 80 and 270-degree beam angles describe specific models, and production runs can drift from those values without notice. Require a golden sample, define acceptable tolerance bands for lumen output, detection angle and hold time in the purchase contract, and reserve the right to test incoming shipments. Price-driven quality risk follows the same logic: listed unit prices on this page range from under one dollar for a 5W bulb to several dollars for higher-wattage corn bulbs, and an unexplained discount against a quoted range usually signals downgraded chips, smaller heat sinks or a lower-grade sensor module. Verify warranty enforcement too, since a two-year warranty is only as strong as the supplier's replacement process.

Sensor Switch LED Corn Bulb Regional Sourcing and Logistics

Two documented locations anchor regional planning for this category: Zhejiang and Anhui, both in eastern China, which places production within reach of major export ports and established lighting component markets. Zhejiang suppliers here combine manufacturer, trading and group-corporation structures, giving buyers a choice between factory-direct pricing and consolidated sourcing across bulb types. The Anhui supplier is a trading company with a fast listed response time, which can suit buyers who want one point of contact across sensor bulbs and adjacent electrical accessories. When a supplier's location is not displayed with confidence, verify the province through the business license before quoting freight.

Logistics planning should reflect the product's physical profile. Corn bulbs are relatively compact but fragile, so confirm export packing details: one supplier lists color box packing per lamp with corrugated carton boxing, which is the format to specify in your contract, along with drop-test expectations for cartons. Weight and dimensional data such as published bulb sizes, for example a 30 by 95mm E14 model or a 73 by 265mm 30W model, let your forwarder calculate carton cube accurately before booking. Match the shipping mode to lead time: if a supplier's listed lead time runs long, ocean freight planning must start earlier, while air freight may be justified for sensor module samples and pilot batches. Confirm which Incoterm the quoted price assumes before comparing suppliers.

Sensor Switch LED Corn Bulb Commercial Terms and Order Planning

Order economics start with MOQ and price bands. One motion sensor bulb listing shows a 3,000-piece MOQ with unit pricing between roughly $1.16 and $1.27, while corn bulb listings range from about $0.56 for a 5W E14 model to about $3.80 for a 30W B22 model, with customization marked available on most listings. Treat these as anchors rather than final quotes: sensor-equipped variants typically carry different economics from plain corn bulbs, and MOQ may differ by wattage or by whether the sensor module is standard or custom-tuned. Ask each supplier to quote your exact configuration in writing, including packing and warranty terms.

Structure payment and production milestones around the verification steps above. A sensible sequence is sample approval against a golden sample, a deposit against production start, inspection before balance payment, and shipment against the agreed Incoterm. Where escrow or platform protection is offered, use it for the first order; where it is not, adjust payment staging accordingly rather than assuming protection exists. Plan order timing around the lead times published on this page, which range from roughly 23 days to roughly 150 days, and build buffer for sensor module procurement if the supplier sources it separately. For reorders, negotiate a rolling forecast with fixed prices for a defined period, and record which certifications, packing format and spec tolerances were contractually binding on the first order so they carry through every repeat purchase.
