How can you tell the difference between T8 and T12 bulbs?
The main difference between T8 and T12 tubes is the tube’s diameter. T12 tubes are 1.5″ in diameter while T8s are just one inch. All other things—socket sizes, lengths, distance between pins—are the same. T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine.
What is the difference in fluorescent tubes?
The major physical difference between T5 and T8 light bulbs is the length and diameter of the tube itself. The T5 tends to be slightly shorter than the T8 tube, and is significantly smaller in diameter. This factor is important to consider when looking at your fixture, because the two tubes are not interchangeable.What is the difference between T4 and T5 lights?
There are many types of fluorescent lights available but the main difference between the T4 and T5 lights are their efficiency or their watt consumption and lumen output, as well as the thickness of the tubes. The T4 has a half-inch diameter, while the T5 is five-eighths of an inch.
How long does a 4 foot fluorescent bulb last?Four-foot LED tubes typically use 15 to 25 watts, while fluorescent tubes of this size use more than 30 watts. Lifespan – This is how long the bulb will last. It’s measured in hours. 50,000 hours is common for LED tubes.

Are T12 bulbs being discontinued?
In effect since July 2012, the legislation eliminates nearly all 4-foot T12 lamps, some 4-foot T8 lamps, most 8-foot T12 lamps, and almost all standard halogen PAR38, PAR30 and PAR20 lamps from the market. T12 technology is over 80 years old. Since that time, lamps and bulbs have been developed that just work better.
What's better T5 or T8?
The T5 has a better lumen-to-watt ratio than the T8, implying that its output is more efficient and brighter per watt of energy used.
Will a T8 ballast work with T12 bulbs?
As far as safety is concerned, you can exchange them. If you place T12 tubes in a fixture with a T8 ballast, you will wear out the ballast and have to replace it. If you place T8 tubes in a fixture with a T12 ballast, then the tubes will have a shorter life due to a higher current through the tube.
Are T8 fluorescent lights good for growing?
Tip. Four T8 fluorescent light bulbs will work well for growing vegetables indoors as long as you leave them on long enough to give the plants enough light.
Is T5 the same as G5?
Fluorescent G5 tube base types are a two pin fitting located at each of the tube with 5mm between the two pins. The T5 (16mm tube diameter) and T4 (12mm tube diameter) uses the G5 cap fitting.
How long is a T8 tube?
The smallest fluorescent tube is the T2 and it has a length of between 250mm and 760mm. The next longest tube is the T4, with a total length of anywhere between 150mm and 1,500mm.
