Questions about this item

Will the 330 W HID arc draw work with my existing electronic ballast?

The lamp is rated at 330 W and requires a compatible electronic ballast designed for HRI short-arc mercury lamps.

How can I verify the 7500 lumen output once the bulb is installed?

A calibrated light meter at the working distance will show approximately 7500 lumens when the lamp reaches full brightness after warm-up.

Does the 54405 package include a ballast or only the reflector lamp?

Only the OSRAM SIRIUS HRI reflector lamp is supplied; a matching 330 W electronic ballast must be purchased separately.
