Purpose and fit
This 250 watt metal halide bulb fits fixtures that accept an E39 mogul base and are rated for M58 operation. It is intended for commercial or outdoor installations that require high-output white light. It is not for buyers who need a standard household screw base or a lower wattage lamp.
Deciding specification
The lamp delivers 21250 lumens at a 4000K colour temperature with a colour rendering index of 65. Verify that the ballast and fixture are approved for 250 watt M58 metal halide before purchasing.
Sustained operation
Rated life is 10000 hours under continuous burning cycles typical of area and high-bay lighting. Output and colour stability are maintained across the rated lifespan when operated on a compatible ballast.

Questions about this item
How bright will the 21250 lumen output appear in a typical high-bay fixture?
The 21250 lumen rating is the initial lamp output; actual delivered light depends on fixture optics, reflector efficiency and mounting height.
What does the E39 mogul base and M58 designation mean for ballast compatibility?
The E39 base fits standard mogul sockets; M58 identifies the ANSI ballast type required for this 250 W metal halide lamp.
What clearance is needed for the E39 base and overall bulb length?
The lamp uses an E39 mogul base; allow enough vertical space in the fixture for the full bulb length plus base depth.
