Import D510 — Buy in Bulk from Supplier in China

The D510 is a mechanically rotary-switched portable flashlight engineered for technical diving, featuring a waterproof housing and high-output LED system. It is designed for operation at depths beyond recreational limits, with a focus on reliability under pressure and in low-visibility conditions. The product is manufactured by Orcatorch Technology Ltd. in Shenzhen, China, and is not marketed for general consumer use.

The housing is constructed from aerospace-grade aluminum alloy with an anodized finish, rated for pressure resistance up to 200 meters. The LED emitter is a single CREE XML2 or equivalent, delivering approximately 1200 lumens with a beam distance of 150 meters. The rotary switch is a mechanical, non-electronic design to prevent water ingress and circuit failure. Battery life is estimated at 3.5 hours on high mode using a 18650 lithium-ion cell, though exact battery type is not specified.

This flashlight is primarily purchased by professional diving teams, marine research institutions, and underwater photography operators who require consistent illumination in extreme environments. Bulk orders are typically placed in quantities of 20 to 100 units, with custom branding available on request. Trade terms are negotiated directly; standard delivery is FOB Shenzhen, with lead times of 15 to 25 days depending on order volume.

Orcatorch Technology Ltd. is based in Building 6, Yusheng Industrial Park, Shenzhen, China, with no additional details provided on workforce, founding date, or production volume. The supplier is classified as harbor-tier and imported, indicating basic verification and export capability, but no response rate or contact history is recorded.

The company appears to specialize in underwater lighting equipment, with the D510 being its only listed product. No claims are made regarding ISO certification, IP testing protocols, or in-house manufacturing of components. Buyers should request independent test reports for pressure resistance, thermal management, and switch durability before committing to bulk orders.
