Get To Know Why Photoluminescent Exit Signs NYC Use Are Very Cost-Effective And Popular


By Cornelia Reyes


Photoluminescence is the ability of a material to produce light without using any commercial power sources, for example, electricity and battery usage. This phenomenon actually has scientific explanation behind it. It normally occurs when certain substances take in photons from another light source and emit the photons in darker places later on. It generates a lighting effect that ranges in brightness. Brightness is dependent on the ability the material to take in photons. The item progressively loses its energy until all the light eventually goes out. This is mechanism through which photoluminescent exit signs NYC uses works.

The materials are often referred to as self-sustaining. This is because they appear to generate their own energy. This has made them quite popular in reducing energy costs. Their use in making exit signs is a testament to this. Without their use, the energy bills charged on NYC government would rise significantly.

Industries committed to green revolution and cost-effectiveness also use these items in the corporate world. Agencies within the federal government charged with making plans for minimizing energy consumption, especially non-renewable energy, favor their use. Apart from reducing consumption of non-renewable energy, the exit signs are also bright, non-radioactive. They also do not emit toxic fumes or contaminate the environment. The items also can be recycled.

Their relevance in maintaining the green revolution going is very obvious. Topping the list is the ability to scale down operational costs of authorities and companies which use them. Maintenance cost of incandescent exit signs is just too great. First, their bulbs have to burn throughout the year. Compounded to this are added cost of faulty wiring repair, replacing batteries and burnt bulbs. In expansive organizations such as corporate bodies and county governments the cost of maintenance for the entire year can rise to significant levels. The best option for such entities is to go for the maintenance-free type that has a long life of a quarter century.

Tritium, LED and compact florescent exit signs are alternatives to the incandescent and photoluminescent ones. They too are cost-effective however compact florescent and LED types require maintenance services. All three of them have a relatively shorter lifespan compared to the photoluminescent type. The tritium one lasts between ten to twenty years while LED and compact florescent ones average eleven and six years respectively.

The fact that they are simple to move when egress ways change comes as another advantage. The florescent and the LED type require rewiring in such circumstances. Whenever comparisons are drawn, photoluminescent type caries the day as the best long-term investment i. E. Monetarily and environmentally.

One popular producer of these items puts total ten-year cost of installation and maintenance at a hundred and eleven dollars per sign. In comparison tritium costs 190 dollars, while LED and compact florescent costs 370 and 894 U. S dollars respectively. The incandescent type is the most expensive of the five costing 1465 dollars.

With the above figures, it becomes very clear the photoluminescent exit signs NYC use has massive benefits. Coupled to this is also their safety profile. It is actually a very excellent way of going green.
