Ketra A20 Lamp

Ketra’s A20 lamp is a fully tunable, calibrated light source that delivers an omni-directional or semi-directional beam pattern. Each lamp is individually addressable, configurable and wirelessly controllable for simple retrofitting applications. The A20 lamp completes the decorative layer of design by enabling Ketra’s advanced tunable spectrum capabilities to be deployed in applications such as wall sconces, pendants and table lamps. Title 24 JA8 and Title 20 compliant models are available in the A20’s high-efficacy configuration. The A20 is equipped with Ketra’s full suite of solutions:

  • High Def Palette – covers a wide range of 16.7 million colors, including pastels, saturated colors and high CRI whites spanning from 1,400K to 10,000K.
  • Dynamic Spectrum—precisely tunes the amount of energy across the visible spectrum to produce Natural Light, Natural Dimming and Vibrancy.
  • TruBeam—produces uniform color across any available beam angle.
  • Color Lock—maintains your desired color point at a one-step MacAdam Ellipse across all Ketra product families and over each product’s lifetime.
