These bulbs are sized to fit older telephone switchboards, signs, instruments, and indicators. 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.

Bulbs for General Electric ET-5 and ET-6 sockets must match the ohms listed on the back of your socket.

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

Your go-to bulbs for everyday use in standard sockets.

Plastic bulbs are shatterproof.

Change out the bulbs in your high-intensity discharge (HID) light fixture to lower energy costs. These LED bulbs last longer than other HID bulbs and achieve the same brightness with fewer lumens. They’re ballast bypass bulbs, so you can install them in a socket that’s wired directly to the power source. Match the wattage of the bulb you’re replacing.

Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a bulb with more than one light appearance. You can adjust the temperature with a switch.
