Within this principle also lay the ability to make bulbs which were considerably darker. Not only due to their glass being painted black but also from the ability to create filaments of varying resistance. These bulbs would come in handy when a person or even a cities whereabouts would have to be concealed in times of war. Light could, for example, not leak from gaps in curtains if the source were both directional, and weak. This would mean aeroplanes or distant troops would not be able distinguish general landscape from potential target.
This also made it possible to determine variety in a light bulbs life span. Producers now had the ability to create bulbs which would die out when they wanted them to, hence the beginning of a malleable industry and market…
   
   

Many other attempts were made towards alternative and efficient means of lighting, one of which was the fluorescent tube, a system requiring quite low energy consumption.
In development by a man around thirty years before the company had even formed, the fluorescent tube would only return forty years later, much improved by another man living in another country.
Comprised of a three-part system, the circuitry has at its heart a pair of nodes on opposing ends of a metre long vacuum tube. One node being the positive node, the anode, and the other node being the negative node, the cathode. Early nodes, or electrodes had been made of iron, graphite and even mercury.
Also in a vacuum, a high voltage current flowing between the nodes, (in combination with a chemical and gasses) emits an ultra violate radiation producing light.

 
 
 
 
Overall, a typical fluorescent lamp would become four to six times more efficient than an incandescent lamp. In order to advertise such a new kind of lamp, various companies had first turned to two venues for installation, one being a chapel, in a distant country, and the other fitted by the company, a low cost household and clothing store in a city not far from here.
