Exterior lighting for your home or business is ensures that the perimeter of your space remains safe and secure. Individuals considering exterior lighting for the first time may be a little overwhelmed regarding what light bulbs they should choose and why, so in this article I will give you advice that will hopefully help you make the right decision for your needs. For your home’s exterior lighting, the most common light bulbs used are flood light bulbs and the common fixtures are landscape flood fixtures. The term 'Flood' does not designate a light bulb type or shape but a beam angle. The most commonly used flood bulbs for the home are incandescent, halogen, CFL, metal halide light, and LED bulbs. The commonly used flood bulb shapes are PAR36s, PAR38s, PAR46s,PAR56s, R, and BR, shaped bulbs. These shapes are offered in nearly every bulb type. You should know that triple and quad tube and 2-pin base bulbs CFLs are also used in outdoor lighting.

, which feature wonderful light quality and variable color temperature.
