Produces only a tiny white speck of light, used as the baseline in the brightness comparison.

Significantly brighter than the 10 lumen torch and enough to light up much of a room.

A torch at one end and softer lantern at the other, with a very large step up in power.

Uses six bulbs, is built to light up the ocean depths and is bright enough to damage eyes.
