EiKO 400W Metal Halide ED37 Lamp – E39 Base | 4000K | 36,000 Lumens

At a glance

When you need serious light, this is your heavyweight.
Throwing down 36,000 lumens in crisp 4000K neutral white, this 400W metal halide lamp is built for big spaces that demand brightness — think high bays, parking lots, arenas, and warehouse floors.
It’s ballast-dependent, dry-location rated, and lasts up to 20,000 hours. Old-school HID power with a modern work ethic.

✅ You need this if:

• You’re replacing a 400W HID lamp in a large-scale commercial fixture

• You need high output and wide coverage (ED37 shape, E39 mogul base)

• You want neutral white light for clear visibility without color distortion

• You’re lighting gyms, factories, outdoor lots, or tall ceiling setups

• You’re keeping your existing HID system running smoothly

❌ You don’t need this if:

• You’re switching to LED or looking for a low-energy alternative

• You need a dimmable option

• You’re working in wet or enclosed locations

• You’re lighting a space smaller than a basketball court
