T4 Light Bulb FAQs

What does the T4 designation mean?

The “T” in T4 wedge bulbs refers to its tubular size, a distinct difference from other bulbs. The number “4” is in reference to the bulb’s diameter in 1/8-inch increments. At 4/8 of an inch, the T4 wedge LED bulb has a half-inch diameter.

Where should I use T4 LED bulbs?

Because of their omnidirectional beam angle, you can use T4 wedge bulbs as path lights or garden lights where they can easily shine the area around the bulb. These bulbs are great when you need a low-profile bulb that can still give people adequate lighting to view notable features or to highlight paths or obstructions during nighttime.

How do I install a T4 wedge bulb?

Installing a T4 wedge bulb is easy with the right lighting tools. Wear insulated gloves to protect yourself from any potential electric shocks, and use a screwdriver to remove any protective plates in the fixture to get access to the slot where the bulb will sit. T4 LED bulbs use a slot or pin system when connecting to power so make sure that you don’t jam the slot or bend the pins before installing the bulb. For additional safety, you can also turn off any electrical power leading into the fixture.

How long do T4 LED bulbs last?

In general, LED bulbs have a long lifespan due to their low wattage and focus on energy-efficiency. With proper maintenance and error-free installation, you can expect a T4 wedge LED bulb to last anywhere between 15,000 and 25,000 hours. You can further extend the bulb’s lifespan by ensuring that it doesn’t stay on all day, creating a lighting schedule with smart devices, or even installing outdoor motion sensors that trigger the bulbs only if someone is nearby.

What are the advantages of using a T4 light bulb?

The biggest advantage of a T4 LED bulb is it small size. This allows you to utiilze small, low-profile fixtures to house the bulbs, which opens the door for minimalist-style outdoor lighting. T4 bulbs are also omnidirectional, which means that it shines light in all directions equally, a must-have when choosing to highlight notable areas or add the right accent lighting to a wall.
