Metal Halide Lamps for HPS Retrofit USHIO Ultra-Arc™ Metal Halide lamps feature the best combination of color balance and color rendering quality available for a direct retrofit into High Pressure Sodium fixtures. The Ultra-Arc lamps are used in High Pressure Sodium fixtures where the high color rendering, and white light of metal halide is desired. Ideal for areas where security is a concern - higher color rendering lamps allow for surveillance/security cameras and eyewitnesses to visually interpret in true colors. Available in T15 bulb shape, E39 mogul base; 250W and 400W with a color temperature of 5200K FEATURES & BENEFITS • High Pressure Sodium Retrofit - No Need to Change Ballast and Ignitor • High Color Temperature - 5200K • Excellent Color Rendering - 85 CRI • High Color Stability • Long Life - Up to 20,000 Hours Average Life APPLICATIONS • Security • Parking Structures and Lots • Downlighting • Commercial and Industrial • Walkways • Bus Stops • Pedestrian Areas *Use with ignitor |

|
Watts |
250WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This Ushio 5001175 Bulb is rated at 250 watts. |
|
|
Base Type |
E39 (Mogul Screw)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 5001175 Bulb has a base type of E39 (Mogul Screw). |
|
|
Bulb Type |
T-15BULB TYPE The bulb type refers to the shape and class of the bulb. This Ushio 5001175 Bulb has a base type of T-15. |
|
|
Rated Average Life |
15000 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 5001175 Bulb has an rated average life of 15000 hours. |
|
|
Color Temperature |
5200 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 5001175 Bulb has a color temperature of 5200 K. |
|
|
Lumens |
20000LUMENS 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 5001175 Bulb emits 20000 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 5001175 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 5001175 Bulb has an operating position of Universal. |
|
|
Bulb Finish |
ClearBULB FINISH The bulb coating of the bulb. Typical values include clear, frost, and colored. This Ushio 5001175 Bulb has a Clear bulb finish. |
