What does T5 mean for grow lights?

Fluorescent lights, also known as fluorescent linear tubes, are classified based on their wattage, shape, and diameter. The “T” in T5 signifies that the bulb is tubular, and the “5” indicates that it is 5/8 inch in diameter. The larger T8 (eight-eights, one-inch) tubes are also popular.

Is T5 a good grow light?

With the exception of LEDs, T5 fluorescent lights are some of the most efficient bulbs that you can buy. You’ll save a ton of money compared to HID, HPS, or MH bulbs if you’re growing seedlings, greens, or herbs, both is energy costs and the cost of venting away excess heat.

How long do T8 fluorescent bulbs last?

LED tubes last an average of 50,000 hours (roughly 16 years) while fluorescent T8 tubes last an average of 25,000 (roughly 8 years).

How long will a fluorescent tube last?

Typical lamp life for a fluorescent bulb is about 20,000 hours, but this can degrade as a consequence of frequent switching (turning on and off). Burning life is extended if lamps remain on continuously for long periods of time.

Are fluorescent lights going to be banned?

The sale of halogen lightbulbs will be banned in the UK from September as part of ministerial efforts to cut carbon emissions. A ban on fluorescent lighting, which is mostly used in offices, will follow in September 2023.

What is the brightest T5 bulb?

Currently, the brightest T5 sized LED tube light is the Philips 473512 LED Dimmable Light Tube. This tube shines with 3500 lumens (54 watt replacement). They cost around $85 for a pack of ten.

Are LED lights better than fluorescent?

Both types of lighting are energy-efficient when compared to traditional incandescent bulbs. LED technology costs more than CFL and fluorescent lighting, but the LED bulbs also last longer and use less energy than fluorescent bulbs. … LED bulbs are also more durable than fluorescent bulbs due to their compact size.

How do I choose a fluorescent tube?

First, you will need the diameter or how wide it is around. This is expressed as a number such as T8 or T12. The “T” stands for tubular, and the number is a measurement of the diameter in 1/8″ increments. So a bulb with a 1″ diameter would be a T8—eight 1/8″ increments.

What happens if you put a T8 bulb in a T12 fixture?

T8 LED tubes won’t fall out if you try to install them in a T12 fixture—they’ll fit just fine. … This is because T12 fixtures have non-shunted tombstones, exactly what you need for LED tubes. T8 fixtures have shunted tombstones, and those tombstones need to be replaced as part of the conversion to LED.

Which is brighter T12 or T8?

The Standard T12 lamp produces 2,650 initial lumens per lamp. The standard T8 produces 2,800 initial lumens per lamp, 6% brighter. But the standard T12 lamp produces 2,300 design lumens and the T8 produces 2,660 design lumens. … Design Lumens are the average lumen output of the lamp after 40% of its rated life.

What is the difference between T5 and T12 bulbs?

T5 tubes are smaller than T8 and T12 tubes, which allow them to fit into smaller spaces. They are offered in sizes of 2-5 feet in length. T5 lamps are around 40% smaller than T8 lamps and almost 60% smaller than T12 lamps.
