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.

These bulbs are sized to fit tight spaces such as signs, control panels, indicators, and flashlights. Brightness is measured in lumens; the higher the lumens, the brighter the bulb.

Incandescent bulbs are traditional light bulbs.

Often used in recessed can fixtures and track lighting, these bulbs produce a focused beam of light. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Bulbs with a warm light appearance have yellow tones. Bulbs with a neutral light appearance are commonly used in workspaces. A bulb’s estimated yearly energy cost is based on 3 hours of usage per day at $0.11 per kWh.

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

Halogen bulbs are slightly more energy efficient than incandescent bulbs, but they generate more heat.

Bulbs that cannot be sold to the regions listed do not meet local energy efficiency requirements.
