This means that as one moves away from a given light fixture, illuminance decreases drastically. For example, consider an incandescent light bulb that is rated at 300 lm. Standing one meter away from this light bulb, one obtains an illuminance of 300 lux (300 lx= 300 lm/1 m2). However, if one moves away from that light bulb an additional 2 meters (i.e., 3 meters total), illuminance changes to just 33 lux by the inverse square law (33 lx= 300 lm/3 m2).
3. According to the decisions made in the previous step, the variety of styles, brightness levels and the likes can be chosen and bought. In addition, one must also ensure that the transformer will be able to take on the load of all the lights that are to be installed.
There are various reasons why our outdoors must be well lit. First, a well-lit outdoor area increases the serenity of the house and earns a few extra thousand dollars when put on sale. Second, it increases the security level of our home by being well lighted. Any unwanted disturbances can be easily monitored and controlled. Based on your requirement, you can design your lighting to be bright or dull. There are many kinds of lights available starting from incandescent lights to solar power lights. While LED based outdoor lamps are cheaper and brighter all the time, and most solar powered lamps become dimmer because of low power saving capacity. Especially during winter seasons, solar power outdoor lamps are of very limited use. On the other hand, LED retrofits consume less energy and do not emit heat or carbons thus enhancing sustainable a lighting environment.
