Type 8 phaser

From Memory Alpha, the free Star Trek reference

The type-8 phaser is a ship-mounted phaser emitter.

In 2370, the Cardassian warship Vetar came under attack by a fleet of small Maquis attack fighters armed with photon torpedoes and type-8 phasers, which inflicted heavy damage to the Vetar. Gul Evek accused the Federation of supplying these supposed civilians with the weaponry, but Captain Jean-Luc Picard assured Evek that however they got them, it was through unofficial channels. (TNG: "Preemptive Strike")

Phasers of the Excelsior-class USS Enterprise were listed as type-8 phaser emitters in the bridge master systems display. (Star Trek Generations)

Legible image of the master systems display was reproduced in Star Trek: The Next Generation Sketchbook: The Movies.
