T5 and T8 lighting is commonly used in industrial warehouses, and are considered the most energy efficient fluorescent lights available for this purpose. There are many misconceptions about the lighting, and we at Cresa will attempt to answer your most frequently asked questions.
The “T” designation actually refers to the shape of the lamp tubular. The corresponding number (5 or 8) refers to the diameter in eights of an inch. For example, a T8 lamp is eight-eighths of an inch, or one inch (2.54 cm), in diameter. T5 lamps are actually shorter in length than their T8 sister. Both T12 and T8 lamps use the medium bi-pin base, which allows T8 lamps to fit into the same luminaires as T12 lamps of the same length.
T5 lamps are fluorescent lamps that are 5/8″ of an inch in diameter. These lamps are becoming increasingly popular but cannot directly replace T8 or T12 lamps because they are a different length and use a different electrical connection.
T8 lamps have improved color characteristics compared to those of standard kreon lighting T12 lamps. The color characteristics of fluorescent lamps are primarily determined by the phosphor kreon lighting coating inside the lamp. The phosphors used in standard T12 cool white and warm white lamps are halophosphates, which usually can only provide either good color quality or high efficacy.
T8 lamps achieve both improved color rendering and high efficacy by employing rare-earth phosphors, which are more expensive than halophosphates. To reduce the cost of manufacturing T8 lamps, the glass tube often is coated first with standard halophosphates and then coated with a blend of rare-earth phosphors.
The correlated color temperature (CCT) of the lamps is controlled by varying the selection of phosphors and the phosphor blend. Like T12 lamps, T8 lamps are available in a variety of color temperatures, including warm (3000 K), neutral (3500 K), cool (4100 K), and very cool (5000 K).
The advantages of T5 lamps over T8 lamps can be summarized as follows: The smaller size of T5 lamps allows for smaller luminaires. kreon lighting The smaller lamp diameter of T5 lamps makes it easier to design optical systems that distribute light in the intended directions. The higher light output of T5 high output (T5 HO) lamps may reduce the number of luminaires needed per project.
A disadvantage of T5 lamps, if they are used inappropriately, is glare. Glare can be prevented, however, by choosing luminaires that shield the light sources from view. Another measure to avoid glare is to decrease the visual size or solid angle of these light sources.
T8 lamps range between kreon lighting $3.00-$5.00 and T5 lamps cost between kreon lighting $5.00 and $12.00. T5 has the highest efficiency which explains the cost difference. T8 produces very little heat, but still has very high efficiency.
