400W Metal Halide Bulb MH400/U/MOG 3 Pack - High Output 36000 lm

In this review of the Bluex Bulbs MH400/U/MOG 3 pack, the bottom line is clear: these 400-Watt metal halide lamps are meant for large-area lighting where high lumen output and dependable color temperature matter. They are best for facility managers, warehouse operators, sports lighting and large outdoor fixtures that require a mogul E39 base. The single biggest reason to buy is the sustained 36000 lumen output at a neutral 4000K with a long service life of roughly 12000 hours, which reduces replacement frequency compared with lower-grade HID options.

Key Features

• 36000 Lumens: Delivers bright illumination suited to high-bay and outdoor fixtures, cutting the number of lamps needed for the same area.
• 4000K Color: Neutral white color temperature provides clear visibility and good color rendition for workspaces and sports areas.
• 12000 Hour Life: Long average lamp life lowers maintenance cycles and total ownership cost for large installations.
• Mogul E39 Base: The mogul base fits standard E39 sockets used in commercial HID fixtures for straightforward replacement.
• Clear ED37 Bulb: Clear ED37 envelope gives direct, unobstructed light output for maximum efficacy in open fixtures.
• ANSI Code M59: Matches M59 ballast fixtures so installers can confirm compatibility before replacing lamps.

Who It's For

The Bluex Bulbs MH400/U/MOG is aimed at commercial and industrial users who need a high-output HID lamp for warehouses, gymnasiums, parking lots, and large retail spaces. Facility teams and contractors who maintain metal halide systems and want fewer replacements will appreciate the 12000 hour average life and strong lumen output.

It is not ideal for small residential fixtures, decorative lighting, or systems that require other ANSI codes or lower wattage bulbs. Buyers should confirm their ballast and fixture accept an ANSI M59 metal halide lamp and an E39 mogul base before ordering.

Pros & Cons

Pros

• Very high lumen output gives excellent coverage for large spaces with fewer fixtures.
• Neutral 4000K color temperature aids visibility and color recognition in work environments.
• Long 12000 hour average lamp life reduces maintenance frequency and replacement costs.
• Mogul E39 base and ANSI M59 code make it compatible with common commercial HID ballasts.

Cons

• As a metal halide HID lamp, it requires the correct ballast and warm-up time, so it is not an instant-on LED alternative.
• The clear ED37 envelope can produce noticeable glare in fixtures without diffusers.
