The light source itself is a small, long-filament lamp with the filament aligned along the supporting rod, making it easy to position on the optical bench.
This simple, high intensity light is extremely suitable for experiments with lenses, prisms and optical gratings.
The long narrow filament is ideal for performing experiments with lenses and gratings.
The lamp housing contains a fan to keep the housing cool to touch.
The lamp is rated 12 V / 15 W
