The light chemically produced by the tropical Photinus fireflies is the most efficient light known to man!

In it 90 % of the energy is converted to the light as compared to the household lamps

in which only 5.5 % energy is converted to light! The rest is wasted as heat energy.

The glow of a firefly contains only 1 /80,000 of the heat that would be produced by a candle flame of equal

brilliance! These beetles provide a spectacular night time light show when the males flash their lights in

perfect unison from the trees. These flickering beams of light-used to attract females- can be seen from

hundreds of meters away. Indeed a cool invitation flashed to the lovely lady beetles!
