About Brightness and Light Appearance

Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.

Bayonet Base Miniature Light Bulbs

Single-Contact Base with Tubular Bulb

Miniature

Pins on either side of the base lock these bulbs into sockets. These bulbs are sized to fit tight spaces such as indicators and vehicle lights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.

Plastic-coated glass and plastic bulbs are more shatter-resistant than glass.

Bi-Pin Base Miniature Light Bulbs

These bulbs are small, but very bright, so they're often used in flashlights and optical instruments such as projectors and microscopes. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

LED bulbs last longer and are more efficient than other technologies. They generate little heat and withstand vibration.
