Use this infra-red light panel for backlighting of animal tanks, cages or mazes made in translucent materials like clear or white plastic and glass. For contrast based video tracking (e.g. LoliTrack and ShuttleSoft) backlighting will eliminate common problems like reflections, diurnal light cycles) or cryptic animals changing color.
Infra-red light is invisible for most animals, but digital cameras are highly sensitive to this range of wavelengths resulting in sharp and well-illuminated images even at low or zero ambient light intensities, e.g. you can track animals in the dark.
