    I would have thought if you want to throw a clear shadow you want a bulb which produces light from the smallest area. If that is right then an older fashioned bulb with a small filament rather than a modern bulb with long tubes.

    You want a point source to cast clearly defined shadows. Perhaps a ceramic metal halide bulb? Maybe even a suitable geometric arrangement of them to project each face of the cube?

    What about a halogen, or, perhaps better, LED? Both are small and relatively strong light sources.

    5 strong, small bulbs with something shielding each bulb's direction from the others.

    one standard screw lamp fitting in the centre, so i guess the smaller the bulb the better :thumbs:

    it doesn't need to be bright enough to cast shadows a long way. what's the smallest size bulb you can get on a standard fitting?

    I would think LED would be good for this, small single point light source, most energy efficient type afaik as well. Can get LEDs in a variety of colour temperatures so a nice stark bright white should be achievable I reckon which would help with getting strong, sharp shadows.

    i work changing lights in offices - best i've come across are Engergizer LED bulbs. They give a clean crisp clear light without any glare. Even on a low wattage they're brighter than most ordinary bulbs.
