- Knife-edge extruded aluminum in whole foot increments up to 12 ft. in one piece. Internal components are die-formed aluminum. Corners are mitered. Continuous wall-mounting bracket with feed access simplifies fixture installation. A mounting rail is installed along the desired wall and housing is then hung on rail, easy installation. Linear fixture is hung and covered in sheetrock creating a cove.
- REFLECTOR
- Integral powder-coated LED housing with excessive reflectivity for increased lumen output
- FINISH
- Standard powder-coated colors are white. Troffer style fixtures are not limited to white, consult factory for special applications.
- OPTICS
- Clear acrylic diffuser is used to protect LED linear strip.
- MOUNTING
- Continuous wall-mounting bracket with feed access simplifies fixture installation. Units may be continuously rowed. Quick-connect hardware provided. Splining hardware provided at fixture joints. Linear fixture is then covered in sheetrock creating a cove.
LED Performance
| LED Output | CCT Color Temp | Watts | Lumens | Lumens per Watt | CCT Multiplier |
|---|---|---|---|---|---|
| Low (indirect) | 3000 | 3.0 WPF | 350 LPF | 118 LPW | 2700=.95 |
| Medium (indirect) | 3000 | 4.3 WPF | 500 LPF | 117 LPW | 3000 = 1 |
| High (indirect) | 3000 | 6.55 WPF | 750 LPF | 116 LPW | 3500 = 1.01 |
| Very High (indirect) | 3000 | 8.8 WPF | 1000 LPF | 115 LPW | 4000 = 1.03 |
- The table above is a quick reference. When calculating loads make sure you add direct and indirect LPW to get total wattage. Please refer to photometric report for detailed information.
- Our light engines are precisely designed for optimal operation of LED assemblies.
- Our standard LED's CCT (correlated color temperature) range is 2700K to 4000K. Other CCT values are available upon request.
- We log LED bin codes for each project we supply to ensure color consistency and keep a record of those projects for future reference.
- CRI offered is 80+, and 90+ Note: on 90+ CRI use .85 multiplier
- Tunable white, warm dim and other special LED colors available.
- Custom Lumens Available
- We design our own printed circuit boards to ensure high luminescence efficiency, low thermal resistance and long-term reliable operation.
- Light engines are easily replaced.
- We use only recognized brand LED's with 3 SDCM (standard deviation color matching) with high color consistency. 2 SDCM available upon request.
- If you require a special LED manufacturer, please contact us. LED chip manufacturers used by Picasso are primarily (but not limited to) Nichia, Cree and Samsung.
- LRP - “LED Reel Program” – LED’s for printed circuit boards come on reels’ like old 8mm projectors and they're sold in lots just like fabric.
