A Cold-light Sphere is a 5cm transparent sphere which glows with a soft light. The sphere is filled with a collection of bacteria in a balanced, sealed ecosystem, one of which produces a bioluminescent cold light. The sphere needs to be exposed to daylight to re-charge it. The sphere glows for 4 to 8 hours after an 8 to 12 hour exposure to sunlight.
If the sphere is stored in a dark space, the bacteria will go dormant; they will survive for up to a year and return to normal functioning when again exposed to light. Exposure to extremes of heat or cold will kill the bacteria and render the globe useless. The sphere is otherwise sealed and does not require external power, nor is it sensitive to external pressures (vacuum to 100 atmospheres).
