400 Watt - Metal Halide HID - Mogul base - ED28 - Coated - 65 CRI - 3700K

Powerful High-Bay Lighting for Demanding Environments

When you need to flood a massive space with reliable, high-intensity light, the SATCO 400-Watt Metal Halide bulb delivers exceptional performance. Producing a staggering 33,900 lumens, this HID lamp is engineered to illuminate large-scale industrial and commercial interiors where visibility is non-negotiable. Whether you are managing a busy warehouse, a manufacturing floor, or a high-ceiling retail showroom, this bulb provides the punch needed to ensure safety and productivity across your entire facility.

The coated ED28 glass design sets this bulb apart by softening the intensity of the discharge arc. This diffusion reduces harsh glare and hot spots, creating a more uniform distribution of light that is easier on the eyes—a critical factor for employees working long shifts under high-bay fixtures. With a 3700K cool white color temperature, it offers a crisp, professional atmosphere that enhances contrast and color clarity, making it far superior to the dingy yellow light of older technologies.

Designed for longevity and durability, this lamp is rated for 20,000 hours of operation, significantly reducing the frequency of costly relamping projects in hard-to-reach ceilings. Its mogul (E39) base ensures a secure fit in standard industrial housings, while its enclosed-fixture rating makes it a versatile choice for a wide range of protective luminaires in dry locations.
