How many Watts Does a T8 light bulb use?
It may be expected that the electric power needed to operate a 32-watt T8 fluorescent lamp will be 32 watts; however, this designation is simply the nominal power of the lamp. The relevant American National Standards Institute (ANSI) document states that the rated lamp power is 32.5 watts under standard test conditions (ANSI C78.81-2005).
What is the difference between T12 and T8 bulbs?
This is a question we often get asked and the answer is very simple. On the most basic level, the T12 and the T8 bulbs have a different diameter tube thickness. The T12 is 1.5 inches in diameter and the T8 is 1 inch in diameter.
What is the difference between a T5 and a T8 flourescent bulb?
Difference Between T5 and T8 Fluorescent Light Bulbs T5 and T8 fluorescent tubes are often used for ambient lighting in commercial areas such as offices. T5 fluorescent light bulb is a newer technology than T8. T5 fluorescent light bulb has an efficiency of about 100 lm/W. T8 fluorescent light bulb can reach about 90 lm/W luminous efficacy.
What does T8 mean in lighting?
What is t8 lighting? The “T” designation in fluorescent lamp nomenclature stands for tubular — the shape of the lamp. The number immediately follow- ing the T gives the diameter of the lamp in eighths of an inch.
How many watts does a T8 light use?
32 wattsA T8 fluorescent that uses 32 watts of energy typically produces 2500 lumens of light. It's LED equivalent, while using only 17 watts, produces 2200 lumens. Additionally, T8 LED light bulbs have a lifetime rating of 50,000 hours, more than 3 times longer than 15,000 hour average lifespan of T8 fluorescent lights.

How many watts does a T4 light bulb use?
There is no industry standard for the length or wattage of T4 tube lights. They can range anywhere from 6 watts to 30 watts, the lower the number the lower the energy consumption, and many lengths. If you are replacing a T4, you may struggle with finding the same fluorescent light bulbs sizes. Be sure to measure the length ...
What is a T8 light?
T8 lights are commonly used in larger spaces as overhead lighting for example in office spaces with troffer lights, garages or classrooms . This is why you will often see long T8 lighting in 4 foot light tubes, 6 feet, and 8 feet lengths. Compared to T5 lighting, the 8 Foot T8 tube lights are less economical.
Why are T12 fluorescent lights still used?
Another reason why they are still used is the cheaper purchasing price compared to the others, but, they are no longer being made. Despite being an older model, the T12 fluorescent tube lights still offer a range of color temperatures at different watts.
What is the smallest fluorescent bulb?
T4 tubes are the smallest of the fluorescent bulb sizes, at only 4 eighths of an inch (0.5 in). Their size is what makes T4 lights popular for under cabinet lighting purposes and accent lighting for displays or a staircase.
What is the color rendering index of T5 bulbs?
The CRi of T5 fluorescent bulbs generally range in the lower end of 70 -80 but there are options with more accurate color rendering up to 95.
Why are T12 lamps the least popular?
T12 lamps are the least popular size. This is because they use older technology that is less energy-efficient compared to the smaller options. T12 fittings use a magnetic start ballast which is less energy efficient. The smaller and newer models have already been fitted with the more energy-efficient electric ballasts.
How long do T5 LED lights last?
