PRO-D Series D2 D4 HID Xenon LED Bulbs

The PRO-D2 and PRO-D4 are two compatible-model options within the PRO-D Series, sharing the same exterior design and core LED-upgrade structure while serving different operating-voltage requirements. Developed for aftermarket HID/xenon-converted headlamp systems, these LED bulbs provide a D2 or D4 replacement option for B2B customers upgrading an existing xenon light-source format to LED. Both models use two customized 8045 LED chips, a 45 V LED-module specification, and a 6,000 K white-light configuration. The main electrical difference is operating voltage: PRO-D2 is specified at AC/DC 90 ± 10 V, while PRO-D4 is specified at AC/DC 45 ± 5 V. This combined page gives distributors, wholesalers, installers, and OEM/ODM buyers one consistent product platform with model-specific electrical data clearly separated for selection.

Structure

The PRO-D2 and PRO-D4 share a compact structure that integrates the LED light source, thermal-transfer components, rear cooling assembly, and connection area into one headlight-upgrade format. Two customized 8045 LED chips form the central light-emitting section, while the supplied product information identifies a 45 V LED module within the PRO-D Series structure. Behind the LED-chip area, a 1.5 mm double-sided copper plate provides a heat-transfer path, and the 3 mm heat-pipe design helps move heat through the bulb body. The construction is completed by a 3010 dual-ball fan at the rear. This arrangement gives the two models the same external appearance while supporting their different D2 and D4 electrical configurations.

1:1 Design and Plug and Play Installation

The PRO-D Series presentation emphasizes a 1:1 design based on the original HID bulb format. For the D2 and D4 models, this design approach helps keep the product focused on the relevant bulb interface and available headlamp space rather than requiring a large external retrofit assembly. A closely matched format is useful for product-selection discussions because the applicable headlamp housing, bulb seating position, and electrical system still need to be considered together. The plug-and-play concept refers to a direct LED-upgrade approach for the matching HID/xenon format. Final fitment should always be checked against the vehicle, headlamp housing, and ballast arrangement used in the individual project.

Perfect Beam Pattern

Headlight performance depends on the relationship between the light source and the optical system, not only on the visual brightness of the bulb. The PRO-D promotional material presents the copper plate, heat-pipe structure, and compact LED-chip layout as a design intended to keep the light-emitting area close to the reference position in the compatible headlamp system. This supports a more controlled beam pattern when an HID/xenon light source is upgraded to LED. By concentrating the LED source in a compact form, the PRO-D2 and PRO-D4 are positioned as headlight-upgrade products rather than general auxiliary lighting. This is relevant for B2B buyers who need a product story based on usable headlamp optics, practical positioning, and a familiar D2 or D4 replacement format.

Dissipation System

The shared dissipation system is one of the core elements behind the common PRO-D2 and PRO-D4 exterior design. Heat is transferred away from the LED-chip area through the 1.5 mm double-sided copper plate and 3 mm heat-pipe design. The 3010 dual-ball fan then supports airflow through the rear cooling section. Together, these components create a thermal-management structure designed to support stable operation across the stated -45°C to +85°C operating-temperature range. For wholesale, private-label, and OEM/ODM programs, this construction provides a clear product benefit: the light source, heat-transfer structure, and active cooling system are presented as an integrated headlight-upgrade solution rather than separate aftermarket parts.

Extreme Brightness

Extreme brightness is the central performance message of the PRO-D Series. For the D2 and D4 models, that positioning is supported by the combination of customized 8045 LED chips, a 45 V LED module, 35 W ballast input, and a 6,000 K white-light specification. The series technical information lists lumen output above 3,500 lm in hot state and above 4,500 lm in cold state. These figures give both models a clear high-output LED position for HID/xenon headlight-upgrade applications. The 6,000 K specification supports a clean white-light appearance, while the separate D2 and D4 operating-voltage options allow buyers to select the correct model according to the applicable electrical configuration.

Certification

The PRO-D Series promotional material presents CE and RoHS certification references as part of the product-range presentation. For distributors, wholesalers, and OEM/ODM buyers, certification documentation should be reviewed against the selected model, the planned packaging and labeling, and the regulations of the destination market. This makes it easier to prepare a product program around the D2 or D4 configuration while keeping customer-facing documentation aligned with the relevant market requirements.

With a shared 1:1 exterior design, customized 8045 LED chips, copper-and-heat-pipe thermal transfer, active dual-ball-fan cooling, and model-specific D2 or D4 electrical options, the PRO-D Series offers a focused LED upgrade platform for HID/xenon-converted headlight systems. The two models can be presented together as a consistent product family while allowing B2B customers to select the appropriate operating-voltage version for their project.
