The advantages In vision Equal distribution of light through smart optics More visibility at lower energy levels in mesopic area (approx.0, 01 to 3 Lux) Better vision by using the most sensitive part of the eye (mesophic vision) No tunnel experience (better peripheral vision) Good colour recognition In Quality Low temperature of light source / charging the light source to the optimum not to theMaximum (no aging/degradation, high lumen output) No phosphors (no aging) Use of high quality materials Lifetime > 80K hoursFully certified (CCC) In cost Low energy use (minus 30% - 70%) No replacement of light bulbsNo maintenanceLow purchase price Better TCO than alternatives For the environment Low CO2 emissionNo use of toxic materialsLess waste over the lifetime (5 x PLL lamps) 100% recyclable No light pollution
