The t12 is 1 5 inches in diameter and the t8 is 1 inch in diameter.
T8 fluorescent lamps vs t8 led tubes.
An led lighting system delivers many more lumens per watt than comparable fluorescents do.
T8 lighting tends to be more expensive and have a shorter lifespan of around 15 000 hours but can last up to 50 000 hours if you choose the led alternatives.
Led replacement bulbs on the other hand calculate end of life at 70 which is approximately 50 000 hours.
This is why you will often see long t8 lighting in 4 foot light tubes 6 feet and 8 feet lengths.
Fluorescent tubes are available in a wide variety of types and sizes.
With linear fluorescent you either had to specially order shatterproof fluorescent lamps or use a tube guard which was costly.
Shatterproof potentially most t8 led tubes are made with a shatterproof coating.
Consider that a typical 4 led tube only consumes between 15w and 20w delivering energy savings above 50 if used to replace t12 tubes consuming 40w each.
A component that will also eventually fail.
On the most basic level the t12 and the t8 bulbs have a different diameter tube thickness.
Typical wattage of a 4 lamps 32w.
You ll avoid the periodic updates to fluorescent lamp standards and save money in the long run.
An led t8 tubelight meant to replace a 32w fluorescent consumes 15 18w.
This is a question we often get asked and the answer is very simple.
Compared to t5 lighting the 8 foot t8 tube lights are less economical.
These are used in private households for example to illuminate basements or garages.
Mercury free leds are mercury free making them environmentally friendly and free from recycling fees.
Easier to control fluorescent lights burn out faster when controls are administered like occupancy sensors.
Tube diameter 8 8 1 t8 lamps click here to buy are used in similar applications as t12 lamps offering superior energy.
Energy efficient on average new t8 led tubes are around 30 more efficient than fluorescent t8 tubes.
Now let s give some attention to led t8 tube lamps.
Oh yeah fluorescent tube lamps require a ballast too.
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 the nearest millimeter.
T5 and t8 fluorescent tubes are the most commonly used types today.
Comparison of fluorescent tube vs led tube.
Lifespan the average life of a t8 led is 50 000 hours versus only 30 000 hours for an average t8 lfl.
