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.

Bi-Pin-Base Miniature Light Bulbs


Tubular Bulb	Pointed Bulb

Often used for general task lighting and in flashlights, projectors, and microscopes, these bulbs are small but very bright. To replace a bi-pin bulb without a trade number, match the base number, voltage, and wattage. The base number reflects the pin spacing from center to center in millimeters—for example, G4 base pins are 4 mm apart. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

LED—Last longer and are more efficient than other technologies.

Bayonet-Base Light Bulbs

Pointed

Bulb

Pins on the base lock these bulbs into sockets to withstand vibration. They're often used in machines and elevators. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.
