This depends on several factors. If you have a fancy cabinet with objects that need illumination, such as expensive china or trophies, then you should definitely install some additional lighting. Also, if you find that during evening hours your one kitchen light is too inferior to provide safe lighting and working conditions then perhaps it is time to invest in some additional light sources.

There are four main types of lighting you can choose from, Rope, Puck, Recessed and linear strips, as well as options for hard-wiring or plug in. First and foremost, you should always consult with a licensed electrician and be sure all power is off to anything electrical that you decide to work on. Secondly, be sure to follow all instructions and safety guidelines.

When you hard-wire something you are essentially tapping directly into an electrical source as opposed to simply plugging something in. This eliminates wasted outlet space but does require at least a limited knowledge of electrical components. Standard practice when installing lights is to place them about 30 inches apart in order to decrease shadowy areas. Another important thing to remember is to install a transformer. Typically cabinet lights run off of a 12 volt direct current whereas a typical household is powered with 120 volt alternating current. It is important to have the right size transformer when transferring DC to AC or vice versa. Usually the more lights you have installed the larger the transformer needs to be.

For safety reasons never place a transformer behind a sealed wall or anywhere out of easy reach. During the manipulation of alternating current to direct current heat is given off. If the transformer is enclosed or packed with dry materials this could become a fire hazard and a danger to your home and family. For this reason transformers should always be left out in the open where they can properly ventilate.

Cabinet lighting also has the great benefit in that it can showcase a backsplash or if your countertops are made of granite or some other stone they will sparkle and shine.  Now that you know why you should install some cabinet lighting, and even a little bit about safety precautions, you can competently choose and install your own do-it-yourself cabinet lighting.
