Direct all external lighting onto a surface and minimise spill light into the sky.
Downlights are generally round or square and recessed into the ceiling, but can also be surface-mounted. Some types of downlight include an open reflector and a shielding device. Generally, the larger the opening, the more efficient the downlight will be. Downlights that contain built in reflective surfaces designed to direct light in a precise direction, can cause the ceiling and upper walls to appear dark, so you must use them appropriately.
Many great downlight choices
The range of new energy efficient halogen light bulbs and spotlight bulbs perform brilliantly when it comes to providing true colours, uplight, downlight, task and directional lighting, and it’s easy when halogen bulbs or spotlights need to be changed.
There's currently also a lot of hype about the design possibilities of LED technology that lasts upwards of 40 years within homes. It’s however likely to be a few years yet before LEDs become a mainstream alternative due to pricing and difficulties in producing the same colour temperature we’re used to for home lighting.
