Lexel Linear is a modular system driving a 48 RGBA high-power LED array, used for wall washing & grazing in the specialty lighting market. It has the ability to produce dynamic color effects and high CRI white light. It is currently used as the main component of Philips ColorWash Lightolier SSL luminaire.
Lexel Linear uses a single controller module design (the power supply is not involved in light control). The LED boards are interchangeable and available in two geometries: one row with 48 LEDs and three rows with 16 LEDs each.
Applications:
- indoor professional wall washing and grazing
- replacing traditional CFL products in recessed, surface mounted and track luminaires
- enabling scene and mood setting flexibility
- creating dramatic light effects
