Instead of or in addition to sconces hidden lights can add a general glow that bounces off the wall and into the room in an even subtler and more diffuse way. Cove lights are built into niches that hide the light source (often a plain LED strip) but hidden lights can also be obscured by medicine cabinets shelving or storage units.
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.
Adding lights to stair risers is beneficial since it can be hazardous negotiating stairs especially at night. Staircases are often enclosed so light them from the sides or embed lights in the risers as a design element.
