Produce bright light and is more energy efficient than regular incandescent
Can be very hot to touch
Halogen bulbs last about 2500 hours.

10. COMPACT FLUORESCENT BULBS (CFLs) are fluorescent lights that screw into regular incandescent light sockets.
CFLs last about 10,000 hours.

11. LIGHT EMITING DIODES (LEDs) are made of crystals on silicon chips about the size of a grain of salt.
LEDs last about 50,000 hours

27. WALL WASHERS spread light over a wall from ceiling to floor.

28. SOFFITT LIGHTING is an enclosed box-like structure with a diffuser at the bottom.

29. LUMINOUS CEILING PANELS are fluorescent tubes placed under plastic panels.

30. STRIP LIGHTS are rows of incandescent bulbs.

31. TRACK LIGHTING is several light fixtures mounted on a metal strip.
