A fixture or two over the island and the table boost general lighting, and dimming allows you to switch moods and move from homework to dining modes.
If you have recessed lighting, the color of the can’s interior, which surrounds the bulb, affects light output and light color. A shiny metal reflector casts the most light but increases glare. A black interior reduces glare but absorbs light, so you might need a brighter bulb.
Some CFLs and LEDs are bigger or heavier than incandescent bulbs. Bring your old bulb with you when you shop to prevent getting a bulb that will stick out.
