Bathroom LED 3 Light 10.5W low wattage Lamps in Matte Black, Antique Copper. Interior design is a process. Specifically, it is the process of integrating into the fabric of architecture. Design never begins with the lighting fixtures; it always begins by determining which surfaces and objects you want to light and then working “backward” toward the solution. Luminaire selection is the last step in this process. By definition, successful lighting design is sustainable design.

It uses the available watts to supply light where it is needed, when it is needed, and limit light from where it is unwanted and unnecessary. Sustainable design requires careful control of light, glare, and power consumption, without waste and in sympathy with the ecology and management of the natural environment. It means making every watt count.
High‐wattage lamps, therefore, are more effi cient than low‐wattage lamps of the same voltage and life rating. Lower voltage lamps, because their fi lament wire is of greater diameter, are also more effi cient than higher‐voltage lamps of the same wattage. Low‐voltage reflector lamps with narrow beamspreads are energy‐saving when their concentrated distribution is used to light small objects at near distances or large objects at great distances, because light is confi ned to the lighted object without spilling beyond it. Where wider beams are required, low‐voltage lamps are often less effi cient than standard lamps.
Low voltage lamps are not of magical construction they are simply incandescent and tungsten halogen lamps that operate between 6 V and 75 V. The increased diameter of the filament wire of low‐voltage lamps allows for a more compact fi lament. The more compact the fi lament, the more precise the beam control. The main advantage of low‐voltage lamps is their precise beam control. An increase in the diameter of a fi lament wire raises the temperature at which it can be operated without danger of excessive evaporation.
Energy‐effi cient is an inaccurate term when applied to either luminaires or lighting design. In every building, the optimum quantity of light must be delivered to where it is needed using the fewest number of watts and the maximum amount of glare control, or the light is ineffective. Every time the optimal quantity of light and appropriate glare control are delivered to where light is needed with the maximum energy effi ciency, we are describing energy‐effective luminaires and energy‐effective lighting design.
