MetroSpec Technology, the leading American manufacturer of custom LED light sources, announces FlexRad 2Tone® and Dim2Tone® are now available in a circadian tunable white solution with Nichia’s Dynasolis™ technology. Dynasolis is Nichia’s Azure™ (Blue-Green) in combination with the award winning H6 series emitter.

MetroSpec’s FlexRad® tunable technology, 2Tone, is a 2-channel LED light source, while Dim2Tone is a single channel source that can be populated with either a single row of alternating emitters or with a dual row of emitters.  Populated with the Dynasolis combination, 2Tone and Dim2Tone can synchronize circadian rhythm with a tunable range between 2700K and 6500K. Dynasolis offers the best circadian solution while maintaining the balance of both lpW & CRI, achieving high Equivalent Melanopic Lux (EML) levels; meeting WELL Building Standard™ requirements ‘L03 Circadian Lighting Design” (Max 3 points) and L08 ‘Electrical Light Quality, Enhanced Color Rendering Quality (1 point).   

“I am pleased that MetroSpec is offering our Dynasolis (H6 plus Azure) solution in its unique technology offerings.  We believe that Dynasolis is the ideal solution for Circadian and HCL (Human Centric Lighting) applications, while still valuing efficacy and a high quality of light,” said Erik Swenson, General Manager, Nichia America Corporation.
