Luminator Signal Flare Capsules are high-intensity beacons, roughly half the size of a standard bolt round, and have two operating modes, steady and stroboscopic. In steady mode they are used for marking and illuminating, and can light an area five metres in diameter. In stroboscopic mode the Luminator Flare flashes on and off hundreds of times per minute and is typically used as a distress beacon. Unlike lamp packs or glow globes, Luminator Flares are one-use only, and are simply discarded when they run out of power.

发光信号照明器是高强度信标，大约是标准爆矢的一半大小，有两种操作模式，稳定和频闪。在稳定模式下，它们用于标记和照明，可以照亮直径五米的区域。在频闪模式下，照明弹光斑每分钟闪烁数百次，通常用作遇险信标。与灯组或发光球体不同，发光照明器只使用一次，当它们耗尽电源时就会被丢弃。
