Bayonet Base Miniature Light Bulbs
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.
Incandescent bulbs are traditional light bulbs.
Plastic-coated glass and plastic bulbs are more shatter-resistant than glass.

Circuit Board LED Light Bulbs
Often used as status indicators, in displays, or to check circuit function in prototyping and testing, these bulbs have wire terminals to directly install onto circuit boards. As LEDs, they last longer, are more efficient, and produce less heat than other types of bulbs. Vibration won’t cause these bulbs to malfunction. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. They require a resistor (sold separately) to limit current.

Blacklight Blue Light Bulbs
Detect UV-reflective materials that are invisible to the naked eye with these bulbs. They contain a blue filter that absorbs the visible light they produce while allowing long wave ultraviolet (UV-A) light to pass through. They appear black when turned off. These bulbs are not for use in bug zappers. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Bulbs cannot be sold to the listed areas because they exceed local regulatory limits on mercury.
