Interior Lighting

Light can define space, substance and style. Outdoors, with the shifting sun and atmospheric conditions, light and the shadows change the appearance of things natural and man made. But in the indoors, the play of natural and artificial lighting largely determine both function and decoration.

The invention of the incandescent bulb in 1978 revolutionized lighting systems as it allowed light to be easily manipulated. Apart from exploiting natural light by using opaque or transparent glass walls, sky lights, large windows etc. for offices, architect work out the detailed light fittings which are conducive for a work environment. In homes, a careful selection of lights extends and enhances the aesthetics of interiors. Similarly for hotels, showrooms, museums, gardens, water bodies, individual lighting requirements are worked out. Artificial light falling from various angles and heights on different surfaces guide us to perceive various features and dimensions while creating a specific mood. With technological developments and the stress on precision lighting, a variety of lighting fixtures are readily available with options which offer manifold possibilities in terms of effect.
