Bright idea for dimmed lighting: To make the most of your lighting install the highest-wattage lightbulb possible then dim it down to accommodate the mood and lighting needs. Consider putting dimmers on both overhead lighting and lamp lighting.
A skylight is like a window on your roof. Simple skylights can be used to bring extra light to a room as a substitute for artificial lighting throughout the day. More complex skylights can even offer an access point for roof maintenance (ideal for checking up on a green roof for example). Skylights can be fixed vented tinted or even combined with an automated shutter system and can include a fly screen. A light tube on the other hand is good for rooms that don’t have a ceiling at roof level. It’s basically a reflective pipe that bounces the daylight down to the room where it is needed. Light tubes can be combined with lighting fixtures so the same area that lets in daylight during the day can double as a light for the evening.
Downlighting is just that: lighting that shines down to illuminate a space. Down lighting can sometimes be referred to as general lighting. Once it was simply the only light source in a room — that single fixture in the middle of the ceiling. If this is your only option placement and quantity of fixtures are the keys to attaining a balanced lighting level while reducing dark corners. Pot lights are also considered downlighting.
