It is a well known fact that many times builders do not install large enough light fixtures in outside areas. Whether they do not realize the importance of having a well lit yard and outdoor area or if they are simply trying to be economical with their plans, often times the outdoor lighting that is installed is insufficient and needs to be changed or added to.
It is extremely important that outdoor areas are well lit as this will discourage the attention of unwanted intruders. It also helps people residing in the home to be able to safely move around outdoors at night time. It also helps, when entertaining outdoors, if the area where your guests are gathered is lit up well.
The main criterion when judging how big your light should be is whether or not it illuminates all of the surrounding areas sufficiently. There should not be too many dim spots or areas where no light reaches, especially on a patio area or outdoor veranda. If you wish to have dimmer lighting on certain occasions it is a good idea to install a dimmer switch so you can adjust the brightness of the lights. It is also recommended that you always leave a light on in your patio at night. You may want to have a couple of lights installed, of different strengths, so you can choose one over the over, leaving the smaller light on at night once you have retired.
If you are not sure what type of ceiling lights are available, a simple search for outdoor ceiling lights online should reveal many different types and sizes of lights you can choose from. You can even purchase patio umbrella lights for decorating around your outdoor patio furniture for parties and get togethers. Remember to match the light with your lighting needs. It is always better to err on the side of buying a light that is slightly larger than you think you will need as you can always install a dimmer later if it proves to be too bright.
