Direct Fixture Compatibility

The Jaspertronics TOPPEST TOP 400 BWS-LAMP is a 380W 18R discharge lamp built for the TOPPEST TOP 400 BWS moving-head fixture. It also fits a wide range of professional beam units including models from Acme, Martin Professional, GTD and others listed in the specifications. The lamp uses a short arc design rated at 7,500 K colour temperature with a CRI of 80.

Bare-Bulb Installation Impact

Supplied as a bare bulb without a housing, the lamp requires the installer to seat it into the fixture's existing lamp holder and align the 1.2 mm arc gap precisely. The compact 58 x 58 x 66 mm envelope and 31.42 mm working distance allow it to slot into the optical path of each compatible model. Correct seating restores the rated 20,000 lumen output and the 1,500 hour average life.

Professional Lighting Operators

Venues such as houses of worship, clubs, concert stages and theatres that run TOPPEST TOP 400 BWS or cross-listed fixtures will regain full intensity with this replacement. Buyers who need a housed module, a different wattage, or a lamp rated for a specific burning position other than any orientation should look at other options.

Questions about this item

When will the 380 W lamp need replacement after 1 500 hours of use?

The average rated life is 1 500 hours; plan to replace the bare bulb once output drops or the arc becomes unstable.

What limits continuous output first during long shows?

The 1.2 mm arc gap and 20 000 lm output mean thermal load on the fixture's cooling system becomes the limiting factor.

How much heat and power does the 380 W discharge lamp produce all day?

It draws 380 W and emits 20 000 lm at 7 500 K, so the fixture must dissipate significant heat; expect warm exhaust air and constant fan noise.
