For a luminous area of 585 x585 mm this equates to 4800 Lumens input.
  • 10. Copyright SLP UK Ltd 2013 Nanoprism is efficient: • As we have stable production transmission is at 89%. Practical measurement. • Nanoprism increases useful flux delivery to the working plane • You can use fewer or lower power luminaires to achieve the same illuminance specification. • Nanoprism decreases intensity above 65° • You can meet low luminance and cut off specifications, we can easily predict Nanoprism behaviour for any specification
