About Replacing Tubular Fluorescent Light Bulbs

Tubular

Medium

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.

Krypton bulbs are known for generating a bright light, such as a flash in a camera. They last longer than incandescent bulbs.

Incandescent bulbs are traditional 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.

Bulbs for General Electric ET-16 sockets must match the ohms listed on the back of your socket.

Wire-Terminal Base Miniature Light Bulbs

Wire terminals allow you to connect these bulbs to a power source through a panel. These bulbs are sized to fit tight spaces such as such as signs, instruments, indicators, and flashlights. 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. They require a resistor to limit current (not included).

Blacklight Blue Light Bulbs

T12

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 Canada because they exceed local regulatory limits on mercury.
