The figure is a strength, not a distance: it scales the brightness the glow is drawn at, with 64 leaving it at its natural level, so the stock systems’ 21 and 25 land at roughly a third of that. Zero or below casts no light at all.

There are two lights, and OneFrameLight chooses between them. With the flag set, the glow is drawn afresh on every frame the system holds a particle, at this strength scaled by how full the system is against ParticleCap; a system of any behavior can carry one. Without the flag, a single glow is thrown at this strength when a Spark system’s first frame bursts, and it spreads and burns out over the next ten frames on its own; that one is drawn only at the highest detail setting, and only the Spark behavior casts it.
