Question:  

What Gobo Size is used for the Exterior Projection Pro Compact?

Answer:

• The fixture gobos have a diameter of 19 mm

Gobo specification:

• External diameter: 19.0 mm +0/-0.3 mm
• Image area diameter: 15 mm

Glass Gobo:

• Minimum gobo thickness: 1.1 mm  +/- 0.1 mm
• Maximum gobo thickness: 3.0 mm  +/- 0.3 mm
• Material: Borosilicate glass

Aluminium Gobo:

• Aluminium gobo thickness: 0.5 mm  +/- 0.2 mm 
• (High-temperature paint towards the front lens)
• Coating: Heat resistant up to 450°C (842° F)

Coated Glass gobos installation:

The heavy matted aluminum coated borosilicate gobos are factory-installed with the more reflective sides facing towards the light source. Replacement gobos must also be installed with more reflective sides facing the light source in order to avoid heat damage. 

More reflective side towards light source 

To minimize the risk of gobo overheating and damage, turn the more reflective side of a coated gobo towards the light source. 

Less reflective side away from light source 

The less reflective side of a coated gobo will absorb less heat if it faces away from the light source.
 

Image/Text gobos:

Gobos that have a specific left/right orientation (such as text gobos) will appear correctly in the projection if they appear correctly when viewed from the side that faces towards the light source.
