Best Answer

In fluorescent tubes the number represents the diameter of the tube. The tubes are measures in 1/8ths of an inch. T8 would be 8/8ths or 1 inch. T5 would be 5/8ths of an inch. Older fixtures took T12 which would be 12/8ths or 1.5 inches.

A T12 bulb is a type of fluorescent light bulb with a diameter of 1.5 inches. It is an older and less energy-efficient version compared to newer T8 and T5 bulbs. T12 bulbs are being phased out in many regions due to their higher energy consumption.

What is the difference between T12 and F12 fluorescent tubes and are they interchangeable?

T12 and F12 tubes have different diameters - T12 tubes are 1.5 inches in diameter while F12 tubes are 1 inch in diameter. They are not interchangeable because they have different fixtures and ballasts. T12 tubes are being phased out due to energy efficiency regulations.


Is a T8 ballast and T8 bulb more efficient then a T12 ballast and a T8 bulb?

A T8 ballast and T8 bulb are more efficient than a T12 ballast and T8 bulb combination. T8 bulbs use less energy and are more efficient than T12 bulbs, so pairing them with a T8 ballast will result in overall energy savings.


Can you replace t8 bulb in fixture now using t12 bulb?

No, you cannot replace a T8 bulb with a T12 bulb in the same fixture. They have different diameters and require different ballasts to operate. It is best to use the correct type of bulb for your fixture to ensure proper functionality and safety.


Can a 34 watt T8 bulb be put in a fixture designed with a 40 watt T12 ballast?

No, it is not recommended to use a higher-wattage bulb in a fixture than what the ballast is designed for. Using a 34 watt T8 bulb with a 40 watt T12 ballast can lead to decreased efficiency, increased risk of damage to the ballast and bulb, and potential safety hazards. It is best to match the bulb wattage with the ballast rating for optimal performance and safety.


How many t12 florecensent use 200watts?

It depends on the wattage of each T12 fluorescent tube. However, a typical T12 fluorescent tube is around 40 watts. So, if you have a total of 200 watts available, you could power five T12 fluorescent tubes.

What is the difference between a F20-T12 CW fluorescent bulb and a F20-T9 CW bulb?

The main difference is the diameter of the fluorescent bulb. The letter T designates the diameter in 1/8" increments. A T9 is 9/8" or 1 and 1/8". A T12 is 12/8" or 1 and 1/2". The CW stands for "cool white" which is in reference to the colour of the light output on a light spectrum chart.
