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.
Dual-Filament Wedge Base Miniature Light Bulbs
Tubular

Wide
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.
Bulbs have two filaments, which operate at two brightness levels. The first filament illuminates a light and the second emits a brighter light when activated similar to a tail light and brake light.
