New Photometric File - Lamp Tilt Information

The Lamp Tilt Information screen allows you to enter Tilt angles and factors for those luminaires whose performance is affected by vertical rotations.

Lamp to Luminaire Geometry

This selection specifies the lamp position within the luminaire when the luminaire is face down.

Vertical Lamp Position - When the luminaire is aimed straight down the lamp is vertical; either base up or base down.

Horizontal along the 90 degree horizontal photometric plane - When the luminaire is aimed straight down the lamp is horizontal and remains in a horizontal position when the luminaire is tilted in the zero degree horizontal angle.

Horizontal along the 0 degree horizontal photometric plane - When the luminaire is aimed straight down, the lamp is horizontal. But when the luminaire is tilted in the zero degree horizontal angle the lamp tends toward a base-up or base-down position.

Number of Angles

Enter the number of angles needed.

Angle Listing

Specify the angles and correlated Tilt Multiplier in the provided table.

• Tilt Angles must terminate with  90 or 180
• Angles listed must be in ascending order (e.g., 0, 45, 90)
