What Is A T8 Fluorescent Lamp

T8 lights are a good choice for an adjustable lighting system because of their color temperature range from a soft yellow white to bright daylight.

What is a t8 fluorescent lamp.

The t12 is 1 5 inches in diameter and the t8 is 1 inch in diameter. Limited testing by nlpip found differences between rated and measured light output values. A common t8 bulb is the f32t8 which uses 32 watts of power. This type of fluorescent tube lighting is the most popular because of its high cri and many color temperature options.

Additionally the t8 uses an electronic ballast that is more energy efficient than the t12 magnetic. A fluorescent lamp or fluorescent tube is a low pressure mercury vapor gas discharge lamp that uses fluorescence to produce visible light. Set your store to see local availability add to cart.

The t12 is an older generation fluorescent bulb that generates light through electromagnetic induction which is considered less efficient method of creating light compared to that of newer electronic based circuits. Figure 1 shows the range of values for rated initial light output that are presently published for 121 lamp models by nine manufacturers for different correlated color temperatures cct. The t12 runs on a magnetic ballast and a t8 operates on an electronic ballast. Fluorescent t8 bulbs have continued growing in popularity since they were brought to the united states in 1981 and have now become the standard in building construction.

These are the basic different characteristics of each different fluorescent lamp type that is most commonly used in offices and commercial industrial lighting all across the world. For fluorescent bulbs the number after f tells you how many watts. A f17t8 is a 17 watt fluorescent t8 lamp. Buy 10 or more 8 37.

The amount of light generated by 32 watt t8 fluorescent lamps varies considerably from one lamp model to the next and from one manufacturer to another. An electric current in the gas excites mercury vapor which produces short wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow a fluorescent lamp converts electrical energy into useful light much more efficiently. The other common lamps are the larger t8 eight eighths inch 1 and t12 twelve eights inch 1 tubes. The most commonly available is the t8 bulbs.

Tube lights under 1800 lumens require fewer watts than t8 lamps that product over 2000 lumens. Even if rated and measured light output values were the same the uncertainties of approximately 1 to 2 would blur the differences between models with similar values of rated. T8 fluorescent lamps are available with a variety of rated light output values.
