	The main drawback of this type of lighting is that the cables that transport the light inside the building also absorb some of this light. This means that the cables can only carry light for a certain distance before it requires amplification. Because of this, hybrid lighting works only in rooms close to the roof level. This means that hybrid lighting has more application is stores, schools, and other public buildings where artificial lighting is used extensively in the daytime.

	The benefits of hybrid lighting are especially noticeable on a bright, sunny day. By bringing natural light into a space the need for artificial lighting is almost entirely removed. This offers considerable energy savings, which lowers energy costs. As well, these systems deliver visible light while blocking [[ultraviolet]] and [[infrared radiation]]. This means that hybrid lighting doesn't warm a building as much as using incandescent or fluorescent bulbs.<ref name="RE1"/> As well, exposure to natural sunlight can reduce the symptoms of depression as sunlight has been shown to increase production of serotonin in the brain.<ref>WebMD Health News.

==How it Works==
Hybrid lighting brings natural light into buildings from one or more mirror dishes installed on the roof. These dishes can swivel to follow the Sun through the sky. These dishes are around 1 [[meter]] in diameter and collect [[sunlight]] incident on the mirrors. The collected sunlight is then funneled down into the building through thick, clear fiber optic rods composed of plastic. These fiber optic rods are fairly thick and are made of plastic cores that transmit sunlight into the building and are wired similarly to electrical wiring.<ref name="RE2"/> Before entering the room the light is fed through luminaries (bulb-shaped ends of the fibre opic wire) that diffuse the light softly, providing lighting for around 100 square meters of indoor space.<ref name="RE1"/> In some cases, light tubes like the one shown in Figure 1 are used. These differ from fibre optic cables in that they are simply large plastic tubes that are coated in some reflective coating to bounce light down into the room.
