T5 & T5 High Output Linear Fluorescent
The USHIO Ultra 5™ T5 Fluorescent lamps were designed to provide
the greatest lumen package in the shortest possible linear tube.
Thus, the Ultra 5 series of lamps provides energy efficiency, high
color rendition, optical control and improved lumen maintenance in
one of the slimmest linear fluorescent lamps on the market today.
Energy Efficiency - A system utilizing Ultra 5 T5 lamps can deliver
up to 104 LPW, thus outperforming standard T8 systems (90 LPW)
and T12 systems (66 LPW).
High Color Rendition - All Ultra 5 T5 High Efficiency and High Output
lamps utilize tri-phosphor coatings for superior color rendering
properties. These lamps have an 85 color rendering index.
Optical Control - With a diameter of only 5/8 inches, the reduced
surface area has allowed luminaire manufacturers to design low
profile luminaires with outstanding optical control. In addition, Ultra
5 T5 lamps work exceptionally in high-bay lighting fixtures where
these T5 systems are replacing Metal Halide systems. With little or
no strike and restrike time, these lamps can be used on dimmers and
sensors and make a logical choice for these retrofit opportunities.
Improved Lumen Maintenance - Through the use of a proprietary
phosphor coating which reduces mercury absorption and a special
coiled cathode, the Ultra 5 T5 lamp is able to maintain a more stable
lumen output over the life of the lamp. Light output of these lamps
actually increases as the operating temperature increases. The light
output of the T5 lamps peak at 95O° F (35O° C) which makes these
lamps especially bright when used in higher heat locations and
