Notes and Formulas:
Luminance: To convert cd/m2 to footlamberts, multiply by 0.2919 | CU Notes/Formulas: | ||||
Cone of Light: | • maintained illuminance=lamp lumens x CU x light loss factors | ||||
|
| room area |
| ||
• Beam diameter is to 50% of maximum footcandles, rounded to the nearest |
|
| |||
|
|
|
|
| |
• Footcandle values are initial. Apply appropriate light loss factors where necessary. | • total number of luminaires=total room area x maintained illuminance | ||||
See Iris catalog for further discussion. |
|
| lamp lumens x CU x light loss factors |
| |
|
|
|
|
| |
| • CU data based on 20% effective floor cavity reflectance. | ||||
