Growing With T5 Light Bulbs

!±8± Growing With T5 Light Bulbs

T5 light bulbs are the first type of light bulb that is serviced only by electronic ballasts. Smaller than previous models in the T series of bulbs, it is infamous for its lumens per watt efficiency. Developed in 1995, it became popular within the United States for the advantages it offered indoor gardeners. It is thus named because of the bulb's tubular shape, and the number 5 represents the diameter of the lamp. Its peak efficiency is achieved at 95 degrees Fahrenheit. The financial savings that it afforded businesses and residential homes compared to previous models, including HO fluorescent bulbs, was astounding. However, the introduction of metal halide lamps quickly eclipsed the glory of the T5.

T5 light bulbs are ideal to use in enclosed spaces where there is not very much room for effective ventilation. It does require constant vigilance though, because the components do require a certain degree of care. These types of bulbs are not the most energy efficient on the market, especially when compared to metal halide bulbs, sodium vapor, or HO fluorescent bulbs. However, compared to older bulbs, they can still cut the potential use of energy in lighting by more than 60%.

Another popular feature of the T5 light bulbs (such as Sylvania Pentron Lamps) is the fact that they have a low mercury content. The bulb itself contains a coating on the inside of the bulb's glass, similar to that of HO fluorescent lights, that prevents the glass and its contained gases from absorbing mercury. This coating reduces the required amount of mercury from 15mg per lamp to 3mg per lamp. To prevent further absorption of mercury, it is most desirable to keep a lamp near its initial output.

T5 light bulbs are roughly 40% smaller than previous T series models. It also uses a smaller bi pin base compared to the medium bi pin base of older models. Like HO fluorescent bulbs, T5 bulbs are prone to developing cold spots. A cold spot rises and falls according to the temperature of the bulb. The life span of a T5 bulb is approximately 20,000 hours. For longevity, it cannot be beat. If you are a beginner gardener, this may be an ideal system for you to invest in because of its comparable low cost. If you change your mind about becoming a gardener, then you will not have wasted time or money on a hobby that disinterests you.
