Compatible Fixtures

The Jaspertronics ACME XP-380 BEAM-LAMP is a 380W 18R discharge lamp built for moving-head fixtures. It fits the ACME XP-380 BEAM, ACME XP-380 BSW, ACME XP 500 BEAM and a long list of other stage and club units. Venues needing a direct replacement for worn arc sources will find the correct part number here.

Build And Mounting

The bare bulb weighs 0.2000 kg and measures 58 x 58 x 66 mm with a working distance of 31.42 mm. Its 1.2 mm arc gap and any burning position allow straightforward installation in tight yoke assemblies. A CRI of 80 and 7,500 K colour temperature deliver consistent white output across the beam.

Upgrade Context

The lamp produces 20,000 lumens and is rated for 1,500 hours of average life. It replaces dimmed or expired 380W beam lamps in fixtures such as the Martin Professional ERA 500 Hybrid IP or GTD GTD-371 II BEAM. The jump is worth it when output has dropped below usable intensity or when the arc becomes unstable.

Questions about this item

What arc gap does the 380 W 18R lamp use, and how does it affect output?

The 1.2 mm arc gap concentrates the discharge, producing 20,000 lumens at 7,500 K with a CRI of 80 for intense, cool-white beam projection.

What are the physical dimensions and working distance needed to mount this lamp in an ACME XP-380 BEAM fixture?

The bare bulb measures 58 x 58 x 66 mm and requires a 31.42 mm working distance from the reflector to align correctly in the optical path.

How is the lamp installed in a moving-head fixture, and which step is most often missed?

Insert the bare bulb into the lamp holder without touching the quartz envelope, secure the retaining clips, then reset the fixture's hour counter — skipping the reset triggers premature replacement warnings.
