Lighting: Rooms

Excessive lighting can affect people negatively. People may get irritated by very intense lights or by too much glare. Light can stir emotions, set the mood, create an atmosphere, offer direction and guidance, or even cause great disturbances. With these things considered, it may be wise to ask: How much lighting do we need? To maximize the positive effects and benefits of lighting on people, there are several factors to consider. These include the dimensions of the room, the kind of light to be used, the intended use of the mom, and some of the light measurements.

The first thing to consider is the dimensions of the room. Measure the length and the width of the room to get the area of the room. For odd shaped rooms, segment them into parts to get the whole area of the room. The area value obtained will then be multiplied to 1. 5 and this will be estimated amount of watts to sufficiently light a room. Adjust this wattage level upwards for rooms that require more lighting like rooms for elderly people and workplaces by multiplying the area of the room o 2. 5 for a higher level of lighting.

The lighting wattage requirement will then be dispersed around the room to achieve both task-specific lighting and appropriate ambient lighting. Another method to use is to know the required number of foot candles to use in a specific room type or room purpose. For example, ten to twenty foot candles are needed in a living room, thirty to forty foot candles for dining rooms, ten to twenty foot candles in a bed room, five to ten foot candles in a hallway, and seventy to eighty foot candles in a tearoom.

One foot-candle of light is the amount of light that a candle can generate one foot away. Measuring the required lumens in a room is also one way of optimizing the lighting in a room. A lumen is a way of measuring how much light gets to what you want to light. A lumen is equal to one foot-candle falling on one square foot of area. To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement.
