ENERGY-EFFICIENT LIGHTING

Introduction to energy-efficient lighting

 

We have gone over 130 years since Thomas Edison or one could argue that Wilson Swan invented the first long lasting electric light bulb. It turns out that the bulb as we know it is extremely energy inefficient despite its numerous modifications - still as of today only 5% of consumed energy is emitted as light, the rest as heat. 

Withdrawal of traditional light bulbs from the market will substantially reduce the CO2 emission to our atmosphere. What is more, it will allow us to save some money. But what, if not the traditional bulb, will light our living spaces? Read our suggestions for the new light sources.

To dispel any doubts, we present you with a short guide to energy-efficient lighting. 

There are numerous alternatives to the traditional bulb on the market - some of those are significantly more cost saving than the others. Among all of those, the most popular are: compact fluorescent lamps (CFLs), LED lamps and halogens.

To begin with let’s talk about the CFLs. These often oddly-shaped fluorescent lamps are the perfect substitutes for our outdated lighting sources. They can be directly installed in any typical lamp socket. In comparison to the traditional bulb, the fluorescent equivalent consumes up to 80% less energy and lasts noticeably longer. Compact fluorescent lamps emit a variety of light colours with the warm one that we all are so used to produced by normal bulbs. These modern light sources turn on quickly and produce an even light. Introduction of the CFLs to the market in 1980 began a new era in the history of lighting. The newest generation of compacts is roughly the same when it comes to their sizes, although they come in various shapes. You could easily distinguish 3 main shapes - normal bulblike shape, tubes and spirals. The best part about them is that they can replace any of your normal bulbs - energy-saving bulbs are available with traditional sockets: E27, E14 and powers.

Alternatively to the CFLs you could buy now very popular LED lamps. This solution is famous for its unbelievable longevity. LEDs last several dozen times longer than normal lighting solutions. These lamps do not emit any heat nor UV radiation. Newest diode technology allows LEDs to be used widely as fully capable light sources. Energy-efficiency, durability and exceptionally long life are among biggest advantages of these lamps and they are the perfect solution for office spaces where the light is on multiple hours a day. When you add that the LEDs are shake resistant, are able to produce basically any light colour without unnecessary filters and their small size you know that you are in for a treat.

Our last candidates for energy efficient lighting are halogen lamps. These bulbs have a wolfram filaments and are filled with special fluoride gasses which allow the filaments to achieve higher temperatures than normal bulbs. High voltage (230 V) halogens can be used in the same sockets as traditional lighting. Halogen bulbs emit a very white light colour, similar to the sunlight. Therefore objects lit with these light sources look natural. This kind of light is perfect to light work spaces, desks or even bathroom mirrors.
