to footlamberts, multiply by 0.2919
Cone of Light:
• Beam diameter is to 50% of maximum footcandles, rounded to the nearest half-foot.
• Footcandle values are initial. Apply appropriate light loss factors where necessary.
See page 64-65 of catalog.
CU Notes/Formulas:
• maintained illuminance=lamp lumens x CU x light loss factors
room area
• total number of luminaires=total room area x maintained illuminance
lamp lumens x CU x light loss factors
• CU data based on 20% effective floor cavity reflectance.
