# How Much Electricity Does A T5 Light Use?

Energy. A four-lamp bay with high-output T5 bulbs consumes 220 watts of electricity, including the ballast; a six-lamp T5 bay consumes roughly 342 watts. T5 bays with four lamps use roughly 6,840 kilowatts (kW) per hour, whereas six lamp bays use about 10,260 kW per hour.

## What is the wattage of a T5 light?

T5 lights are offered in two output levels: regular and high. Standard T5 lights have wattages of 14, 21, 28, and 35 watts. T5 bulbs with high output (T5 HO) are offered in 24, 39, 54, and 80 watts (49-watt T5 HO lamps are also available from GE Lighting). The attributes of the conventional T5 and T5 HO lamps available in the United States are summarized in Table 1-2. In the United States, a four-foot-long, 54-watt variant with 5,000 lumens is popular. Because of the high light output, fewer luminaires are required to reach the same illuminance levels as other fluorescent lights. T5 HO lights, on the other hand, are slightly less efficient than ordinary T5 bulbs, as seen in Table 1-2.

The features of four-foot standard T8 and T12 lamps are shown in Table 1-3. The rated average lamp life of normal T5 and T5 HO bulbs is 20,000 hours, which is the same as most standard T8 and T12 lamps. T8 and T12 bulbs with extended life last 4,000 to 10,000 hours longer than T5 lamps. (These lamps are not included in Table 1-3.) RE80, a rare earth phosphor with a color rendering index (CRI) of 85, is used in all of the lights in Tables 1-2.

## What does it cost to keep a T5 light on?

The cost of a kilowatt hour in my city is 10.29 cents. So it cost me about 62 cents each day to run two 4 foot panels with four lamps each for 12 hours. This works out to about \$19 a month. That works up to about \$226 each year. From October through the end of March, I exclusively use my lights. So, for \$113, I could get roughly 60 plants. How old are you, 60? Thirty were nearing completion, and another thirty were in the works for a second batch that would finally be finished outside. These would have already bloomed and started to set fruit at this point. That’s a lot of joy, food, and contentment! It’s what I refer to as \$113 worth of therapy.

## Is it better to use LEDs or T5s?

For a long time, T5s were thought to be the most energy-efficient tube light alternative. LEDs, on the other hand, have closed the gap and are currently predicted to save 45-65 percent of the energy used by T5 bulbs. T5s are being left in the dust as LEDs continue to improve.

Fluorescent lights and incandescent bulbs are inefficient when compared to LED bulbs. T5, however, remains the best and most efficient fluorescent alternative.

Efficiency of LEDs According to Energy.gov, broad LED adoption by 2027 could save 348 TWh of electricity. At today’s electricity pricing, that’s the annual electrical production of 44 1,000-megawatt electric power plants, saving more than \$30 billion.

## T5 or T8: which is better?

The T5 has a higher lumen-to-watt ratio than the T8, which means its output is more efficient and brighter per watt of energy utilized. Because of its smaller diameter, the illumination is more focused and concentrated in a single point, making the T5 a perfect light for performance. T5 lights are brighter and more powerful than T8 lights, however they might generate glare and over-stimulate the plants.

## Is it possible to replace T5 bulbs with LEDs?

LED T5 bulbs that are plug-and-play or direct wire make transitioning from fluorescent to LED a breeze. Installing these bulbs is simple and quick. It will not be necessary to replace the ballast in your current fixture because it plugs straight into the fixture and does not require any rewiring.

## When it comes to T5 lights, how close should they be to plants?

You’ll want to hang your T5 grow lights 12 to 18 inches above your plants when it comes to hanging them. Unlike HIDs, which require 18 to 20 inches of space above plants, and LEDs, which require 20 to 24 inches, T5s do not have the same intensity as other lights.

## Is T5 a suitable choice for growing?

T5 grow lights are one of the most effective types of lighting for growing any type of plant, from vegetables to the most delicate flowers. This is due to T5s’ high efficiency, which allows you to save money on electricity while still producing brilliant, intense light.

## What exactly does T5 light imply?

T5 lights are fluorescent lamps with a diameter of 5/8″ of an inch. Only linear T5 lights are discussed in this study. Compared to traditional fluorescent lamps, the difference in length and socket pin design prevents any complications with electric circuits or human factors. The physical features of T5 systems are compared to T8 systems in this section.

The letter “T” in lamp nomenclature refers to the lamp’s tubular shape. The number after the “T” usually denotes the lamp’s diameter in eighths of an inch (1 inch equals 2.5 centimeters). T5 lights have a diameter of 5/8″, which is equal to 5 times an eighth of an inch. These lights are almost 40% smaller than T8 lamps, which have a diameter of one inch, and nearly 60% smaller than T12 lamps, which have a diameter of 11/2″. Diagrams of lamp ends for T5, T8, and T12 lamps are shown in Figure 1. Figure 1 further demonstrates that T5 bulbs have a different pin base than T8 and T12 lamps. T5 bulbs have a small bi-pin base, whereas T8, T12, and T14 lamps have a medium bi-pin base.
