Product Description |
|
|
OSRAM SIRIUS HRI are bright, high performing compact discharge lamps designed to deliver spectacular light effects in small, lightweight moving head fixtures. As the designed in lamp for many major moving head manufacturers, the SIRIUS HRI provides exceptional brightness and beam control with long average lifetimes (3,000 hours for 190W+).
Product features and benefits
Today more than ever, outstanding stage shows come to life through breathtaking light effects. Therefore, the applied light sources have to provide an especially high brightness. With the high-performance SIRIUS HRI® series, OSRAM has developed reflector lamps which play to their strength, especially in small and lightweight moving heads. They are characterized by high luminance, reduced weight and very compact dimensions with an optimized burner for every operating position. Moreover, they show a very stable light output, as the high luminance decreases only slightly over the entire lifetime (between 1500 and 6000 h). The special reflector design allows for an easy and fast lamp replacement, as the burner is already perfectly adjusted within the reflector. SIRIUS HRI® is supplied as a complete system including ECG. Combining reliability, efficiency and luminance, the lamps can be used flexibly in various applications of entertainment lighting. |

| General Specifications | |||
|
Watts |
231WATTS A unit of electrical power. Lamps are rated in watts to indicate the rate at which they consume energy. This OSRAM 4052899553538 Bulb is rated at 231 watts. |
|
|
Volts |
70VOLTS A measure of "electrical pressure" between two points. The higher the voltage, the more current will be pushed through a resistor connected across the points. The volt specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 277 V) refers to the line voltage it must be connected to. This OSRAM 4052899553538 Bulb is rated at 70 volts. |
|
|
Rated Average Life |
2500 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 OSRAM 4052899553538 Bulb has an rated average life of 2500 hours. |
|
|
Color Temperature |
8000 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 OSRAM 4052899553538 Bulb has a color temperature of 8000 K. |
|
|
Lumens |
10800LUMENS 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 OSRAM 4052899553538 Bulb emits 10800 lumens. |
|
|
Color Rendering Index (CRI) |
75COLOR 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 OSRAM 4052899553538 Bulb is rated at 75 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 OSRAM 4052899553538 Bulb has an operating position of Universal. |
