What is T5? The "T" in T5 is a way of identifying the bulb size. T5 lights are the smallest diameter fluorescent bulbs available. They are 5/8 of an inch in diameter, about the size of a dime, as opposed to T8 or T12 bulbs which are larger. T5 bulbs are also shorter than T8 and T12. The reason they are so popular with hydroponics is because they are even more efficient and put out more lumens per watt than larger bulbs. T5 bulbs are slightly more expensive, but for hydro growers looking to get the most yield out of their gardens, this cost is not significant.

Why Choose T5 Lights? Fluorescent lights, especially T5's, are extremely energy efficient. This is great for hydro farmers because when growing a garden, you have to leave the lights on for up to 12 hours a day. If you have a light that produces a lot of heat, that heat is wasted energy and ends up increasing your electricity bill, not to mention the extra cost of installing and running high powered fans to dissipate that heat. Your plants might even consume more water if your light is releasing too much heat into the environment, especially if you use a grow tent. T5 lights produce ambient temperature of only 95 degrees, and do not require much, if any additional ventilation.
