T5 Fluorescent

What Does T5 Fluorescent Mean?

T5 fluorescent lights are similar to other types of fluorescent lighting and have been around since the 1950s. The light derives its name from the fact that it is a tubular fluorescent lamp that measures ⅝ of an inch in diameter.

Two new versions debuted in the 1990s, including a high-efficiency model and a high-output model. All are well-suited for use in indoor and hydroponic gardening set-ups.

Maximum Yield Explains T5 Fluorescent

A wide range of fluorescent bulbs can be used as grow lights for indoor/hydroponic systems, but the T5 fluorescent bulb is perhaps the most common.

Growers must be careful to select bulbs specifically designed for plants, rather than common household lights. It is also important to understand the light emission range of different T5 fluorescent bulbs. For instance, bulbs with a 3000K (Kelvin) rating produce more light in the red spectrum, helping to encourage flowering. Bulbs with a 6500K rating provide a full-spectrum of light and are ideal for overall growth.

A T5 fluorescent bulb is 5/8th of an inch in diameter, making it smaller than some other options out there. Most fixtures that use T5 bulbs cannot accept T8 or T12 bulbs, and vice versa, although there are some fixtures available that can be modified to accept multiple types of fluorescent bulbs depending on the grower’s needs.

T5 bulbs emit less heat than traditional HID grow lighting. The lack of heat also aids growers in saving money on exhaust systems because they don’t have to vent out as much excessive heat. The closer proximity of the lights to the plants saves space and allows for a smaller growroom or grow tent.

T5 fluorescent lamps are available in a large variety of brands. They can produce 100 lumens per watt. Unlike other grow light options, the T5 fluorescent lamp uses less energy but produces more light. In most situations, they require about 60 per cent less energy to operate than other types of grow lights but continue to give ample lighting. Typically, the T5 has a lifespan of about 20,000 hours.
