Philips Advance LI533-H4 Ballast Ignitor

The Philips Advance LI533-H4 is a metal halide ballast ignitor kit rated for 450 W operation. It supports a single 400 W bulb and is supplied in a Val-U-Pak Plus (77L) package for new installations or direct replacements.

Installers needing one 400 W metal halide fixture

This kit suits electricians and facility teams wiring one metal halide lamp up to 400 W with the ballast mounted within 25 ft of the lamp. Projects that require multiple lamps per ballast, higher wattage, or longer lead lengths should look at a different solution.

Maximum distance to bulb 25 ft

The ballast must be installed no farther than 25 ft from the lamp to ensure reliable starting and operation. Exceeding this distance can prevent the ignitor from striking the lamp or maintaining stable output.

How far can the lamp sit from the ballast?

The ignitor supports a maximum lead length of 25 ft between ballast and bulb.

Will the 1 5/8 in diameter body fit my existing housing?

The cylindrical case measures 1 5/8 in across and 2 1/2 in long; verify your enclosure clearance against those dimensions.
