Silver Bowl: Metallic finish on the top half of the bulb softens the light. A great solution for overheads with exposed bulbs especially if there isn't a dimmer.
Soft Pink: Emits a gorgeous rosy glow, perfect for mood lighting since its coloring looks great on your skin.
Round Chandelier: These bulbs look great in an open chandelier.
Edison Bulb: Visible Filament bulbs give a soft warm glow since they are low wattage and look great hung on their own.
Incandescent: White Light, Low Voltage (12-24), and they require transformers.
Fluorescent: (CFL's) greater energy and longer life than incandescent. These also come in rope lighting and cove lighting which are great for under the cabinet lighting.
Halogen: Offer bright white light which is good for task or accent lighting. These are usually low voltage, but do put off some heat.
Best Wattage for each situation:
50-70W: Staring at a Computer
70-80W: Putting on Makeup
