• Use a Satco metal halide HID lamp that delivers 36000 lumens while operating at 400W, supporting high-output HID applications where strong light levels are required. The ED28 lamp type and Mogul (E39) base help support straightforward replacement in compatible probe start metal halide fixtures.
• Provide a crisp 4200K Cool White appearance with a wide 360 degree beam angle to support omni-directional illumination for general area lighting. This broad distribution helps support uniform output in commercial and industrial spaces where consistent coverage is important.
• Designed for probe start systems and listed as non-dimmable, supporting stable operation in typical metal halide fixture environments. Universal operating position adds flexibility for installation across different socket orientations found in many legacy HID installations.
• Plan maintenance cycles using the published 20000 hour rated life, helping set clear expectations for relamping schedules in facilities that rely on metal halide performance. Published wattage, lamp type, and base details support consistent purchasing and replacement planning.
• Compliance information supports specification needs, including RoHS compliant status and California fields marked exempt - base not regulated with lawful for sale status. California Proposition 65 notes Lead, and published mercury content of 59.0 supports environmental documentation requirements.
