Product Description |

Ultra 5™ T5 Linear FluorescentT5 & T5 High Output Linear Fluorescent The USHIO Ultra 5™ 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™ 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™ 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™ 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™ 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 95° F (35° C) which makes these lamps especially bright when used in higher heat locations and compact luminaires. Features & Benefits

|
Watts |
39WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This Ushio 3000393 Bulb is rated at 39 watts. |
|
|
Base Type |
G5 (Miniature BiPin)BASE TYPE The base is the end of the lamp that fits into the receptacle connected to the electrical supply. There are many types of bases used in lamps, screw bases being the most common for incandescent and HID lamps, while bipin bases are common for linear fluorescent lamps. This Ushio 3000393 Bulb has a base type of G5 (Miniature BiPin). |
|
|
Bulb Type |
T-5BULB TYPE The bulb type refers to the shape and class of the bulb. This Ushio 3000393 Bulb has a base type of T-5. |
|
|
Rated Average Life |
40000 hrsRATED AVERAGE LIFE This is the manufacturer provided rating for the average expected life of a lamp. For most lamp types, rated lamp life is the length of time of a statistically large sample between first use and the point when 50% of the lamps have failed. Note, this is not a manufacturer guarantee of life, but an estimate based on typical average testing. It is possible to define a "useful life" of a lamp based on practical considerations involving lumen depreciation and color shift. This Ushio 3000393 Bulb has an rated average life of 40000 hours. |
|
|
Color Temperature |
4100 KCOLOR TEMPERATURE A measure indicating the degree of "yellowness" or "blueness" of a white light source. Measured in kelvins, Color Temperature represents the temperature an incandescent object (like a filament) must reach to mimic the color of the light emitting from the lamp. Yellowish-white ("warm") sources, like incandescent lamps, have lower color temperatures in the 2700K-3000K range; white and bluish-white ("cool") sources, such as cool white (4100K) and natural daylight (6000K), have higher color temperatures. The higher the color temperature the whiter, or bluer, the light will be. The lower the color temperature the more yellow the light will be. This Ushio 3000393 Bulb has a color temperature of 4100 K. |
|
|
Lumens |
3500LUMENS A measure of the luminous flux or quantity of light emitted by a source. For example, a dinner candle provides about 12 lumens. A 60-watt Soft White incandescent lamp provides about 840 lumens. This Ushio 3000393 Bulb emits 3500 lumens. |
|
|
Color Rendering Index (CRI) |
85COLOR RENDERING INDEX (CRI) An international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more true colors generally appear. CRI ratings of various lamps may be compared, but a numerical comparison is only valid if the lamps are close in color temperature. CRI differences among lamps are not usually significant (visible to the eye) unless the difference is more than 3-5 points. This Ushio 3000393 Bulb is rated at 85 CRI color rendering index. |
|
|
Operating Position |
UniversalOPERATING POSITION Mercury and High Pressure Sodium lamps may be operated in any burn position and will still maintain their rated performance specifications. Metal Halide and Low Pressure Sodium lamps, however, are optimized for performance in specific burn positions, or may be restricted to certain burn positions for safety reasons. This Ushio 3000393 Bulb has an operating position of Universal. |
