What are T5 4-Foot Bulbs?

So, what exactly are T5 4-foot bulbs? Let's get down to the basics. "T5" refers to the bulb's tubular shape, with a "T" meaning tubular and the "5" indicating the diameter in eighths of an inch. So, a T5 bulb is 5/8 inch in diameter. These bulbs are a type of fluorescent lamp, specifically a slimline fluorescent lamp. They're typically long and slender, designed to fit into a variety of fixtures. The "4-foot" part is pretty straightforward – it refers to the length of the bulb, which is approximately four feet long. These T5 4-foot bulbs are often used in situations where you want bright, even lighting without taking up a lot of space. Think of them in under-cabinet lighting, shop lights, or even in some types of track lighting. They're a versatile option that can really make a difference in your lighting setup.

Now, a little more about how they work. T5 bulbs use a process called fluorescence to produce light. Inside the glass tube, there's a small amount of mercury vapor. When electricity flows through the bulb, it excites the mercury atoms, causing them to emit ultraviolet (UV) light. This UV light then strikes a phosphor coating on the inside of the tube, which converts the UV light into visible light. Pretty cool, right? This process is much more energy-efficient than traditional incandescent bulbs, which generate light by heating a filament. That's one of the big reasons why T5 4-foot bulbs have become so popular. They offer a great balance of light output and energy savings, which is a win-win for both your wallet and the environment. Keep in mind that T5 bulbs require a ballast to operate. The ballast regulates the current flowing through the bulb and provides the necessary voltage to start and maintain the arc. There are different types of ballasts, including electronic and magnetic ballasts, and they can affect the bulb's performance and lifespan. We'll delve into that a bit later.
