How Much LED Light Does My Room Need?
The amount of light produced by a bulb is measured in Watts. Traditionally, wattage is quite simple to understand,with a higher wattage producing a greater amount of brightness, and a lower wattage producing less brightness, but with the proposed phase out of inefficient incandescent bulbs and the more towards “green" LED lights, it can be difficult to understand the wattage equivalent, and how much light your room requires.
Rooms Without Natural Light
Rooms that lack any sort of natural light, such as lofts or attics, will generally require a higher powered bulb than rooms with large windows, for example. You may also find you need a greater amount of light in craft rooms or kitchens for example, which is where an LED downlight really comes in handy,giving a bright spotlight effect. With traditional incandescent bulbs, 100 Watts is considered to be a bright bulb. However, to create the same amount of light from an LED, you should be looking at a 10 Watt LED bulb.
Rooms With Restricted/Limited Natural Light
For rooms with small windows, or for rooms with windows that are obstructed by buildings or foliage, a medium wattage is ideal. 60 or 75 Watt incandescent bulbs are the perfect blend of dim, atmospheric glow and usable light. For LED lights, look for a 10 or 12 Watt bulb to create the same effect. If you find that you require additional light, during the evenings for example, or in times of poor weather conditions, a desk lamp or a few table lamps can really help boost visibility while minimising energy output.
Rooms With Abundant Natural Light
Natural light is by far a superior option as it's environmentally friendly and completely free, but sometimes even rooms with abundant outdoor light shiningmthrough need a bit of help. A simple lamp may well do the job here, but if you'd rather use a ceiling light or a crystal chandelier, for example, opt for a low wattage bulb that produces a dim light. In terms of incandescent bulbs, a 40 Watt bulb should be more than adequate. An 8 Watt LED should do roughly the same job.
Of course, sometimes it can be difficult to determine how much light you will need in any given room, as visibility can change significantly due to the weather, the seasons, or even the interior decor. For example, you may find that cream coloured walls reflect natural light well, but if you redecorate to darker colours, the room may become a bit too dark. If you anticipate varying conditions in your home, consider a dimmer switch which will allow you to alter the amount of light in your room quickly and easily.
