Philips 320W Metal Halide Lamp

This Philips 320W pulse-start metal halide lamp delivers 30000 lumens at a 4100K cool white colour temperature. It fits fixtures with an E39 mogul screw base and carries the manufacturer part number 383810. The transparent ED28 envelope suits industrial and outdoor installations that require high-intensity discharge output.

30000 lumen output with 20000 hour life

The 30000 lumen rating provides strong illumination for high-bay warehouses, sports courts and area lighting where broad coverage is needed. A 62 CRI means colour discrimination is limited, so the lamp is not suited to retail display, galleries or tasks that demand accurate colour rendering. Rated life reaches 20000 hours before replacement is required.

E39 mogul base for pulse-start ballasts

The lamp requires a compatible pulse-start metal halide ballast and an E39 mogul socket; it will not operate on standard probe-start gear or smaller bases. The ED28 bulb shape fits common industrial reflectors, freeing the specifier from sourcing special housings. Ensure the fixture is rated for 320W pulse-start operation before installation.

Questions about this item

Will the E39 mogul screw base fit the ballast and socket I already use for 320 W metal halide lamps?

The bulb uses an E39 mogul screw base, which is the standard socket for 320 W pulse-start metal halide fixtures, so it will fit existing compatible ballasts and sockets.

How can I confirm the 320 W pulse-start lamp is operating correctly once installed?

After warm-up the lamp should deliver 30000 lumens at 4100 K cool white with a CRI of 62, matching the rated output for the 383810 model.

Does the package include a ballast or any mounting hardware, or is it just the ED28 bulb?

The box contains only the 320 W ED28 metal halide bulb with E39 base; a compatible pulse-start ballast and mogul-base fixture must be purchased separately.
