If you are determined tofeature deer antlers s in your room then you need to consider the overall balance of the interior design. The rustic "look" does tend to feature the "more is more" school of interior design - but antlers are such a design statement its wise to consider the overall design statement of the room or house.
If you are featuring a large and intricate chandelier then you may find it best to keep the other light fittings in the room to a more restrained style - though still in overall keeping of the rustic theme. Natural wood and brass fittings as well as cow-hide shades are often used in confunction with antler lights. This puts the focal point of the room firmly on the feature light fixture.
Alternatively you can layer a room so that you not only include antler light fittings of various sides but also include antler furniture and other deer, elk or moose inspired items including skins, mounted pieces, decorative rugs and art featuring the animals which discarded the antlers originally. Soft furnishings featuring leather and other natural materials will also carry the theme through.
When you are in the process of choosing your light fixtures make sure that you remember to keep the practicality of your lighting plans in mind. If the room is designed as say a dining room then its a good idea to ensure that there is a light fixture above where the table will be placed. If the room is a general living room then you may want to have a variety of lights which ensure that there is task lights for people sitting and reading but also overall general lighting which can be controlled to make activities such as eating or TV watching comfortable.
Antlers are often used in masculine rooms such as home bars or pool rooms. You can get specific antler pool table lights which are designed to ensure that players have the best light on the playing surface. If there is a built in bar then it is easy to include bar lights often on a exposed bar which feature smaller deer antlers.
Whatever you decide you will find many different antler light fixture available for almost any design situation in your home.
