Overview

The Ushio BC2378 UHI-S150DM/A/UVP is a 150-watt metal halide bulb built for high-output, energy-efficient lighting in professional and commercial settings. Operating at 4200K, it produces a neutral daylight-white light that renders colors accurately, making it well-suited for retail displays, architectural fixtures, grow light setups, and studio environments. At 13,000 lumens, the BC2378 delivers roughly three to five times the light output per watt of a comparable halogen bulb, which translates directly into lower energy costs for the same level of illumination.

Built around a G12 2-pin base, this bulb is designed to drop into compatible professional fixtures without modification. Its 10,000-hour rated lifespan means fewer replacements over the life of an installation, a meaningful consideration in hard-to-reach or high-use fixtures. As with all HID lamps, a compatible ballast is required, and the bulb will need a few minutes to warm up to full output after switching on. For anyone maintaining or upgrading an existing metal halide lighting system, the Ushio BC2378 is a proven, efficient choice from a manufacturer with decades of experience in specialty lighting.
