What is a Fluorescent Light or a CFL? Fluorescent light bulbs are a specific type of gas-discharge light (also known as a high intensity discharge, HID, or arc light). CFL is an acronym that stands for compact fluorescent light. Standard fluorescent lights are available in tubes (generally 48 to 84 inches in length).

What is the difference between fluorescent and compact fluorescent light bulbs?

Q:What’s the difference between a compact fluorescent light bulb and a linear fluorescent bulb? A: The primary difference is size and application.

What are fluorescent light tubes called?

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light.

Is it safe to smash fluorescent tubes?

Fluorescent tubes contain mercury, which can be dangerous if released so be careful not to break them. … Mercury is toxic, and can cause serious damage to the brain, kidneys, lungs, nervous system and other vital organs. Therefore, fluorescent tubes should always be disposed of properly.

What is the difference in fluorescent tubes?

The major physical difference between T5 and T8 light bulbs is the length and diameter of the tube itself. The T5 tends to be slightly shorter than the T8 tube, and is significantly smaller in diameter. This factor is important to consider when looking at your fixture, because the two tubes are not interchangeable.

How do I identify fluorescent tubes?

Lamps are typically identified by a code such as FxxTy, where F is for fluorescent, the first number (xx) indicates either the power in watts or length in inches, the T indicates that the shape of the bulb is tubular, and the last number (y) is the diameter in eighths of an inch (sometimes in millimeters, rounded-up to …

Are all fluorescent tubes the same?

A small percentage of this mercury can be released into the air if the bulbs are broken. … Mercury can cause poisoning in some circumstances. Even so, people are encouraged to replace their “old fashioned” incandescent bulbs with CFLs.

Are fluorescent tubes toxic?

Which gas is used in CFL?

In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

Why did they stop making CFL bulbs?

The growth of technology for CFL bulbs stopped soon after their initial peak in 2007, because of their notoriously slow start-up time. “It’s kinda been the product that everybody loves to hate,” Mr. Strainic said, as reported by The Verge. LED, he said, was simply the better product.

Which is better LED or CFL?

Longevity—With a lifespan of approximately 25,000–35,000 hours, an LED bulb lasts 2 to 4 times longer than a CFL, and 25 to 35 times longer than a standard incandescent bulb. … LEDs are more efficient than even CFLs: A 16.5-watt LED bulb is equivalent to a 20-watt CFL and a 75-watt incandescent.

Can a T8 tube replace a T12?

The easiest and lowest price option to replace a T12 is a T8 linear fluorescent. They have become the go-to option for pre-existing T12s. If you still have magnetic ballasts, switching to a T8 will require a ballast swap.

What causes a fluorescent light to go out?

A dead fluorescent can be caused by lack of electrical power (tripped breaker or blown fuse), a dead or dying ballast, a dead starter or a dead bulb(s). … defective starters, defective bulbs or a defective ballast. IMPORTANT: Flickering fluorescent tubes can cause the ballast to overheat and fail prematurely!

How do I know if my ballast is T8 or T12?

If no markings are available, the size in diameter of the tube is the easiest way to determine the type you have installed. T8 tubes are 1-inch in diameter and T12 tubes are 1 1/2 -inch.

What is T5 fluorescent tubes?

A T5 is a type of fluorescent tube. It differs from a T12 and a T8 in its diameter. All T5s are 5/8ths of an inch (T8s are exactly 1inch thick and T12s are 12/8ths or 1.5 inches thick). T5s are 16mm in diameter making them the thinnest fluorescent tube out of the three.

What is fluorescent material?

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. … Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after.

What is the standard size fluorescent tube?

While there are multiple types of LED and fluorescent tube lights, the three most common are T12, T8 and T5. The terminology comes from “T” for “tubular” and the diameter of the bulb in eighths of an inch, so “T8” represents a tube of 8/8ths of an inch, or 1 inch.

Which is better T5 or T8?

T5 lamps are smaller and more efficient than T8 bulbs. T5 lights are the winner between the two, they do cost about 2x more than T8 options. While T8s are cheaper upfront, T5s are a more affordable option long-term and are great for most growing needs.

Will a T8 fit a T12?

T8 tubes are simply 1 inch in diameter versus the 1.5 inch diameter of T12 tubes. In an effort to make LED tube lights compatible with the internal dimensions of most fixtures, you will find that most LED tube lights feature a T8 or 1 inch diameter. They can indeed be used in T12 fixtures.

How do you make fluorescent lights less harsh?

Today, the most common way to hide the harsh glow of fluorescent light is with plastic covers for fluorescent light fixtures. Almost every fixture has them. Typical plastic covers for fluorescent light fixtures come in a few styles. The most common are prismatic and frosted light fixture covers.

What's the difference between T8 and T12?
