Import 22mm Ad16-22e Indicator Light B Type Pilot Lamp — Buy in wholesale FOB from Supplier in China

The AD16-22E B type from Zhejiang Ninuo Electric Co., Ltd is a 22 mm circular pilot lamp built around an LED source with a colour rendering index of Ra 80. It accepts input voltages from 6 V up to 380 V across both AC and DC supplies, and is offered in white, green, red, yellow and blue. The unit mounts in a standard 22 mm panel cut-out and carries an IP65 rating, indicating sealed construction against dust ingress and low-pressure water jets. Continuous operating life is specified at more than 30 000 hours, positioning it for long-service industrial installations.

The B type designation in this series typically refers to a specific bezel or terminal configuration within the AD16 family, though exact mechanical differences from the D type or other variants are not detailed in the source. The Ra 80 CRI is a notable specification for an indicator lamp, suggesting the LED phosphor blend renders colours with reasonable fidelity, useful where operators distinguish status by subtle hue differences. Housing construction is standard flame-retardant thermoplastic, with internal voltage-dropping components sized for the broad 6 V to 380 V range. As with most multi-voltage indicators, the same physical housing is used across the range, with internal resistor or capacitor values selected for each voltage grade.

Target purchasers include switchgear manufacturers, process control system integrators, and electrical wholesalers supplying maintenance departments. The AD16-22E B type fits control desks, generator panels, conveyor system enclosures and building management interfaces. Because the listing groups all voltages under one product page, buyers must specify the exact operating voltage when requesting a quote to receive the correct internal configuration. Packaging, MOQ and lead time are not provided and should be clarified with the supplier before finalising procurement.

Zhejiang Ninuo Electric Co., Ltd is based at No.1, Pioneer Road, Backstreet Industrial Zone, Liushi Town, Yueqing, Zhejiang Province, 325604, China. The company markets its indicator products under the "NIN" brand. Its platform trust tier is recorded as "harbor", and both response rate and average response hours are shown as zero, indicating no response history is currently logged. Buyers should therefore initiate contact early in the sourcing process and verify supplier responsiveness before committing to large orders.

No data is available on the company's founding year, production floor space, employee count, or annual revenue. The product catalogue appears centred on AD16-series pilot lamps and signal indicators for industrial and household electrical applications. The listing describes the AD16-22E as suitable for both industrial and household use, suggesting the company targets a broad market segment. Prospective buyers should request a factory profile, quality management system documentation, and reference customers to assess capability.
