Which is bigger T5 or T8?

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.

Are T5 bulbs being discontinued?

Lamps affected include fluorescent 4 foot T8, T5, T5HO and 2 foot U-bent lamps. However, many 32W lamps have either been re-engineered or discontinued by the manufactures. Most current fluorescent T5 linear lamps already comply with the new standards. The 2015 rule-making takes effect in January of 2018.

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.

Where do you usually use a T5 fluorescent?

T5 luminaires are usually used in new construction projects. Because T5 lamps have smaller diameters, shorter lengths, and higher luminances than T8 and T12 lamps, they are more suitable for indirect lighting, direct/indirect lighting, direct lighting for high-bay applications, and wall-washing applications.

Which is better LED or T5?

LEDs also offer increased light efficiency when dimmed as opposed to T5 fixtures and usually produce more lumens per watt in general, which decreases energy usage and thus, energy costs. A lower wattage of LED luminaire will usually be just as efficient, sometimes more, as a higher wattage T5 lamp.

Are all T5 bulbs the same?

Are t5 and t8 bulbs interchangeable? T5 and T8 lamps have different diameters so they are not usually interchangeable. The pin sockets will only line up and complete a circuit in a correctly sized ballast. The exact design of each ballast differs across manufacturers.

Is T5 better than LED?

What kind of T5 light bulbs are there?

The high-output T5 (T5 HO) lamps are available in 24, 39, 54, and 80 watts (49-watt T5 HO lamps are also available from GE Lighting).

What’s the average life of a T5 Ho lamp?

As Table 1-2 shows, however, T5 HO lamps are slightly less efficacious than standard T5 lamps. Table 1-3 illustrates features of four-foot standard T8 and T12 lamps. Standard T5 and T5 HO lamps have a rated average lamp life of 20,000 hours, the same as most standard T8 and T12 lamps.

How is the light output of a T5 lamp measured?

Light outputs are measured during lamp operation on reference ballasts under standard laboratory conditions. T5 lamps are operated at 35°C (95°F) compared to T8 and T12 lamps, which are operated at 25°C (77°F). Mean light output means lamp light output at 40% of rated lamp life.

How often should I replace my T5 light bulbs?

But by the two year mark the efficiency even for the highest quality bulbs can drop a great deal so I would suggest to replace T5 bulbs every year for best results or very two years if you want to save money but still have great results from your lighting.
