Notes:
1. All measurements were taken using Osram SharXS
®
HTI
®
1500 W/D7/60 lamps.
2. Light output values are nominal and based on the average output of a sample of production luminaires.
3. The illuminance (I) values listed in foot candles (fc) and lux are measurements taken at the center of the beam.
4. Vari-Brite mode was set to DMX value 255, which opens (splits) the internal lens for maximum light output.
5. Internal-lens Zoom settings: narrow (rear position - DMX = 0), mid (mid position - DMX = 127), wide (front position - DMX = 255).
6. TN values: For the beam angles listed in the table, the coverage diameter (ø) = TN x D (throw distance). For example, a Clear front lens and a
Buxom internal lens at the narrow Zoom setting produces a beam with an angle of ~29º, which provides ø = 21 ft at D = 40 ft. For other dis-
tances (D) at this Zoom setting, multiply the TN for 29º x D. For example, at 50 ft, ø = .517 x 50 = 26 ft. Conversely, to get ø = 30 ft with the 29º
angle, D = ø/TN = 30/.517 = 58 ft. You can use the TN values for the other beam angles in the same way.
