Notes and Formulas:

Luminance: To convert cd/m2 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.

Note: Specifications and Dimensions subject to change without notice.
