The t12 is 1 5 inches in diameter and the t8 is 1 inch in diameter.
T8 fluorescent lamps vs t8 led tubes.
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.
An led lighting system delivers many more lumens per watt than comparable fluorescents do.
Easier to control fluorescent lights burn out faster when controls are administered like occupancy sensors.
Lifespan the average life of a t8 led is 50 000 hours versus only 30 000 hours for an average t8 lfl.
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.
An led t8 tubelight meant to replace a 32w fluorescent consumes 15 18w.
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.
This is why you will often see long t8 lighting in 4 foot light tubes 6 feet and 8 feet lengths.
Led replacement bulbs on the other hand calculate end of life at 70 which is approximately 50 000 hours.
Fluorescent tubes are available in a wide variety of types and sizes.
These are used in private households for example to illuminate basements or garages.
Oh yeah fluorescent tube lamps require a ballast too.
T5 and t8 fluorescent tubes are the most commonly used types today.
Now let s give some attention to led t8 tube lamps.
Typical wattage of a 4 lamps 32w.
You ll avoid the periodic updates to fluorescent lamp standards and save money in the long run.
It should first be noted that led t8s have a higher initial cost than fluorescent t8s which can be purchased for only a few dollars in some cases.
On the most basic level the t12 and the t8 bulbs have a different diameter tube thickness.
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.
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.
A t8 bulb is considered end of life at 60 of its light output which equates to roughly 14 400 hours.
Energy efficient on average new t8 led tubes are around 30 more efficient than fluorescent t8 tubes.
A component that will also eventually fail.
