When selecting what type of exterior lighting you're going to install, there are some important elements that need to be considered. Fixtures intended for exterior use are designed to withstand rain, wind, heat, snow, dust, and other influences generated by weather that can wear away at the life of a fixture. Even though the rating of the fixture is important, in terms of UL and IP ratings, the quality of the fixtures is also a key factor. You need to look for options made with durable materials such as polycarbonate lenses to avoid shattering, silicone gaskets to prevent the entry of moisture, and resistant housings that are built to last.
A general rule of thumb is that the more lumens a fixture provides, the higher up it should be placed so the light output isn't overly harsh. If a lighting solution has a high lumen output that is concentrated within the beam spread, it could be too harsh if placed at eye level or below. On the other-hand, if a lighting solution has a lower lumen output and is placed up high it will lead to illumination becoming too widely dispersed to be effective. So, if you follow these simple steps you can easily determine the right placement for lighting based on its lumen output.
Another aspect you need to take into account when choosing exterior lighting for apartments, is what color temperature and color rendering it provides. For example, if the color temperature is too warm, the light output will have a yellow tinge, which is less flattering to the eyes than a cooler white tone. Also, cool temperature lights also tend to offer a better color rendering of objects than warmer tones. Having the proper color temperature and CRI are crucial in implementing a lighting solution that makes renters feel safe in their apartment setting.
Even though there is a certain level of light pollution is unavoidable in this location, there are some measure you can take to help reduce it. For example, parking lot spaces need ample light, but that light needs to be primarily focused downward at an angle that is opposite of apartment windows. When it comes to walkway lighting in the form of poles, it needs to be placed between windows on the opposite of the walkway opposed to directly in front of windows. If you take these two steps into consideration, it will reduce the chance of direct light spread from affecting an occupant's comfort.
