Sylvania 400W E39 Mogul Metal Halide
The Sylvania M400/U/ED28 is a 400 watt metal halide lamp with an E39 mogul base measuring 1.53 inch in diameter. It produces an initial output of 32000 lumens at a 4000K colour temperature and carries a rated life of 15000 hours. The ED28 envelope suits fixtures designed for this form factor.
Suits high-bay and area lighting needing 4000K
This lamp fits installations that require the M59/E ANSI code and a 400 watt metal halide source with an E39 base. Buyers needing a different wattage, a different base type, a higher colour rendering index than 65, or a longer rated life should look at other options.
E39 mogul base with M59/E ANSI code
The E39 mogul base and M59/E designation are the critical identifiers for ballast and fixture compatibility. Verify that the existing ballast is rated for a 400 watt M59/E metal halide lamp before installing this unit.

Questions about this item
Will the 1.53 inch diameter E39 mogul base fit my existing fixture?
The lamp uses an E39 mogul base with a 1.53 inch diameter, so it fits any socket designed for that base size.
What is the correct orientation and ballast requirement for installing this M59/E metal halide lamp?
It is a universal burn position lamp that must be operated on an M59/E ballast rated for 400 watts.
When should I plan to replace the lamp given its 15000 hour rated life?
The average rated life is 15000 hours; schedule replacement near that point as lumen output declines toward the 20000 lumen range.
