High-wattage metal halide lamp

The SYLVANIA PowerArc 66633 is a 1500 watt metal halide bulb built for fixtures that accept a T7 double-ended lamp with an RX7S base. It suits commercial or industrial lighting installations where high-output discharge light is specified.

Thermals and power in normal use

Rated at 1500 watts, the lamp draws substantial power and generates significant heat during operation. Adequate fixture ventilation and correct ballast matching are essential to maintain stable performance and lamp life.

Behaviour under sustained load

Continuous operation at full rated wattage maintains consistent light output provided the ballast and fixture thermal limits are respected. The RRSC designation indicates a specific envelope construction intended for reliable long-term cycling.

Questions about this item

How do you install the Sylvania 66633 1500W T7 DE RX7S bulb, and what step is often missed?

Insert the double-ended RX7S base firmly into both socket contacts until fully seated; the step often missed is verifying the lamp is horizontal within the fixture to prevent premature failure.

What maintenance or replacement will the Sylvania 66633 1500W T7 DE RX7S bulb need later?

Replace the bulb once light output drops or colour shifts noticeably; metal halide lamps require no cleaning if the fixture lens stays sealed, but always change it before the rated life ends to avoid rupture risk.

What limit shows up first on the Sylvania 66633 1500W T7 DE RX7S bulb under sustained use?

The 1500 watt power draw creates significant heat, so the fixture's thermal limit is reached first; ensure the enclosure is rated for 1500W T7 double-ended lamps to prevent overheating shutdown.
