photographic studios & industries.The bulb was developed by the

Early Modern Fluorescent Bulb.HistoryIn 1927, the high pressure
vapor lamp was invented.
High pressure vapor lamp.HistoryIn 1976, Edward E. Hammer,
invented the CFL spiral tube. In 1995, spiral lamps were
manufactured in China
CFL spiral tube bulb.Other InformationThe CFL has a poisonous
vapor called mercury, that can be released in high concentration if
the bulb is broken.CFL stands for Compact Fluorescent Light or
Energy Saving Light.
Purpose The CFL bulb has a longer life span that lasts up to
15,000 hours, than the incandescent that has 1,000 hours.It also
uses less energy.And it is eco-friendly.
Creates light by a current reaction, with argon gas and mercury
vapor.
Pins pass a current to an electrode, which electrons strike
atoms of vapor. This produces UV radiation that bounces off
phosphor coating.
The fluorescent powder on the inside of the tube energizes
electrons in phosphor atoms. Then atoms radiate white light. The
