With energy-efficient LEDs and CFLs, it is much easier to light your house effectively without driving up your electric bills. Although these bulbs, especially LEDs, are initially somewhat more expensive, they last for tens of thousands of hours. 

To plan lighting for both home security and when entertaining, it is generally best to plan for two separate lighting layouts. The intensity, location, and light color quality are different for optimal security and entertaining. For example, your security lighting layout must be larger and cover hidden areas that guests will never visit.

Brighter, more intense lighting is better for entertaining than for security. High color temperature LED bulbs or integral fixtures produce a whiter light. This is great for entertaining and makes colors look more like they do in daylight. These are often called “daylight” bulbs on the packaging or 4,000K or 5,000K bulbs. The higher the Kelvin rating of the bulb, the cooler and more blue the light emitted will appear. With a lower Kelvin, the light is warmer and more yellow.

For security, a less bright light with a lower color temperature in the 2,700K range is best to use. If brighter security light is used, it causes a person’s pupils to get smaller from the glare. This makes it more difficult to see in unlit or very dimly lit areas where a crook may be hiding. 

Entertainment lighting

Planning your lighting for entertaining is fairly simple, so do this first. You know where you and your guests will be and what activities will typically be going on. 

Lighting around your front door is the first area that every guest sees, and you want it to be as welcoming as possible. Bright, whiter light is ideal here. Select two fixtures from one-quarter to one-third the height of your front door so they don’t look too small or too large for the entrance area. The center of the bulb should be 66 to 72 inches above the floor. This also provides a nice appearance from the street.

LED bulbs or integral LED light fixtures are the best choice for the front door. This is particularly true in colder climates. LEDs reach their full brightness almost instantly. CFLs take a few seconds to warm up and get bright when it’s cold.
If someone knocks on your door, you want full brightness as soon as you switch on the lights. For other fixtures where the lights are on for a while, CFLs are fine.

For general entertaining where less bright lighting is adequate, consider using low-voltage landscaping fixtures around a deck or patio. These are very easy and safe to install yourself. This also provides the opportunity to change or add to the lighting pattern at any time in just a few minutes.

It’s also good to install shielded light fixtures. These block the light from shining up into the sky. This light is wasted and contributes to light pollution. Light pollution is annoying to neighbors and a danger to birds and wildlife. Visit darksky.org for more information.

Security Lighting

Security lighting planning takes more thought, and there are more lighting options. If a house and yard are illuminated properly, a thief will usually avoid it. To plan security lighting, switch on the indoor lights that you normally use. Take a walk around your house and look for locations that are not lighted. Pay particular attention to windows or doors that may be somewhat hidden by shrubs or other landscaping from view. These are important areas for efficient light fixtures.

PAR38 LED floodlight bulbs are a good choice for specific areas like these. PAR38 bulbs come in a variety of beam angles to fit the area of coverage you need. The angles range from 10 degrees, which is narrow for smaller areas, to 50 degrees, which is a wide flood.

One of the most efficient and effective types of security light is a motion-sensing fixture. The time that the
light stays on is adjustable from
15 to 60 seconds, so little electricity is used. When the light comes on, a thief assumes he was seen and leaves. For more security, select a two-level model that keeps a dim light on until it brightens when motion is detected.

Solar-powered LED motion-sensing models are the easiest to install yourself. Any floodlights should ideally be located nine feet above the ground to be
most effective.
