Definition
A bengal light is a static device that burns with an intense, steady coloured flame and no projection: red from strontium, green from barium, blue from copper, white from magnesium. Packaged as a pot, a cylinder or a handled torch, it lasts 30 seconds to three minutes and bathes everything around it in its colour. It is used to tint a façade, a bridge, a lakeshore or an alley, often by the dozen lined up and lit together by quick match or igniters. Bengal lights give off a lot of smoke and considerable heat, which calls for a non-combustible support. Handheld bengals for the public fall in F1 or F2; display pots and stage torches go up to F3, T1 or T2.
In practice, for the display company
Bengal lights come by the dozen and sit on fireproof supports: they are a rigging and clean-up job more than a firing one. PyroDesk manages them by quantity in stock and quotes, groups them on one cue or one fuse line in the firing plan, and PyroSimulator renders the coloured light cast onto the 3D scenery of the site.
