What is the wattage of T5 fluorescent tube?
T5 lamps are available for standard output and high output. The wattages for standard T5 lamps are 14, 21, 28, and 35 watts. 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).
How long do T5 grow lights Last?
Time: With typical daily photo periods of 8-12 hours, T5 bulbs carry the average life-span is 9-12 months. If it’s been more than 12 months since your last bulb change, it’s probably time for a change.
How many T5 lights do I need for veg?
Figuring out the number of T5 grow lights you need for your plants all comes down to the lumens they’ll need. This is pretty easy, especially if you keep in mind that plants need 2,000 to 5,000 lumens per square foot. Smaller veggies, clones, and seedlings need around 2,000 lumens/sqft.
How far should a T5 be from plants?
When it comes to hanging your T5 grow lights, you’ll want to hang them around 12 to 18 inches above your plants. Unlike HIDs that you’d need to hang 18 to 20 inches above plants, and LEDs that need 20 to 24 inches of space above plants, T5s don’t have the same intensity as other lights.

How much electricity does a T5 light use?
Energy. A four-lamp bay using high output T5 lamps uses 220 watts of power including the power used for the ballast; a six-lamp T5 bay uses approximately 342 watts of electricity. Four-lamp T5 bays use about 6,840 kilowatts (kW) of electricity per hour, with six lamp bays consuming about 10,260 kW per hour.
What does T5 mean in lighting?
What does T5 mean? The “T” in lamp nomenclature represents the shape of the lamp-tubular. The number following the “T” usually represents the diameter of the lamp in eighths of an inch (1 inch equals 2.5 centimeters). T5 lamps have a diameter equal to 5 times an eighth of an inch, or 5/8″.
What is the average luminance of a T5 fluorescent lamp?
While the standard T5 and T5 HO are the same diameter and length, the 4-ft T5 is rated at 2,900 lumens, similar to the lumen per watt output of a T8 lamp. On the other hand, the 4-ft T5 HO lamp is rated as high as 5,000 lumens, offering twice the maintained light output of a T8 lamp.
Are T5 lights energy efficient?
The higher the value, the more energy efficient the lamp is. The luminous efficacy of T5 lamps is about 100 lm/W, while those of T8 and T12 lamps are only about 80 lm/W and 70 lm/W respectively.
Is T5 better than LED?
There is no physics difference in light being produced by an LED or T5 unit; however reflectors in different units can affect whether light beams are more collimated (better penetration in deep tanks) and of course, different units produces light of different spectrum/wavelengths.
