Downward pendants bring light close to a key surface like a dining table or side table which helps create a sense of intimacy. Upward pendants and general-glow pendants give a more ambient light to the room’s core with the former letting light bounce downward off the ceiling first while highlighting any overhead features in the process.
Have a beautiful or shapely ceiling? Uplights will bring attention to it and indirectly bounce light back down. Plus they are often combined with a wall washer so the architecture is fully on display. Uplights can also act as wall washers when installed in the floor especially in contemporary homes. The effect of many wall washers and pot lights can be a bit modernist and even a little cold so use this effect only if you enjoy a minimalist gallery-inspired look. Ultimately when implemented correctly a great lighting scheme won’t necessarily be the first thing you notice. But layers of light coming together to bring out the best in your space will make sure that wherever your eyes do fall all they will see is a perfect photo-ready finish.
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.
