315w Ceramic Metal Halide Lamp

The 315 W ceramic metal halide lamp from Weifang Hengxin Electronic Co., Ltd is a high-intensity discharge luminaire built around a ceramic arc tube rather than traditional quartz, delivering improved colour stability and longer service life. The lamp operates at 315 W nominal power with a colour temperature range of 3000 K to 4000 K and a luminous efficacy that exceeds conventional metal halide alternatives. Colour rendering index is typically 90 or above for ceramic arc tube designs in this wattage class, though the exact CRI value should be confirmed with the supplier. The ceramic tube construction tolerates higher operating temperatures and resists chemical degradation from halide salts, which is why horticultural and retail lighting buyers have shifted toward this technology.

Light output maintenance is a critical parameter for commercial buyers: standard ceramic metal halide lamps retain 80 percent of initial lumens at 8,000 hours and often reach 20,000 hours rated life under three-hour cycle operation. The 315 W format has become the dominant single-ended size for vertical indoor farming and high-bay retrofit because it balances photon flux density with canopy penetration. Weifang Hengxin Electronic does not state the exact lumen maintenance curve or PPFD values for horticultural use, so growers should request spectral distribution charts and micromole-per-watt data before specifying this lamp for controlled-environment agriculture.

Applications span retail display lighting, warehouse high-bay illumination, sports hall overhead lighting and horticultural grow operations where full-spectrum output and UV suppression are valued. The lamp is designed for standard E40 mogul base or PGZ18 socket depending on variant, compatible with electronic ballasts rated for ceramic metal halide. Weifang Hengxin Electronic holds imported-tier status with harbour trust classification, indicating the profile has passed basic verification but carries no response-rate data. Buyers should request ballast compatibility sheets and confirm whether the offering is single-ended or double-ended, because 315 W ceramic metal halide lamps ship in both formats and socket mismatch will prevent installation.

Weifang Hengxin Electronic Co., Ltd is located at No.269 Fengshou Road, Qingzhou, Shandong Province, China, placing it within the Weifang industrial corridor known for electronics manufacturing and agricultural machinery. The supplier is classified as imported-tier with harbour trust status, meaning the profile has been imported into the platform directory with basic field validation but shows zero response rate and zero average response hours. No factory size, year of establishment, ISO certification scope or export licence details are provided in the listing, so buyers must independently verify business registration and manufacturing capability.

The company positions itself as a lighting manufacturer, specifically in ceramic metal halide lamp production, yet the listing does not disclose whether it operates a full vertically integrated factory or assembles from sourced arc tubes and caps. Shandong Province hosts several major phosphor and glassware suppliers, so local sourcing of ceramic tube blanks is plausible but unconfirmed. Importers are advised to request a factory audit report, product certification such as CE or UL, and reference customers in their target market before committing to container-volume orders.
