The Nasmyth Series are an installation friendly and budget conscious alternative to Kellwood's Nitsch Series Vapour-proof linear LED light fittings.

In the Nasmyth light fitting, an innovative end cap design provides access to wire-in terminal blocks whilst allowing for an IP65 rating. These features make this luminaire ideal, not only as task lighting in industrial lighting applications but also in external applications including car park lighting.

Linear lights designed for


The lightweight design and high efficacy allow for high lux levels with minimal load requirements. A choice of mounting styles and optional linkable configuration provide further flexibility, making the Nasmyth Series an obvious replacement for traditional batten and anti-corrosive fittings.

  1. Ingress protection: Anodised aluminium provides environmental protection rating at IP65. Easy access to terminal blocks ensures fast and flexible installation whilst maintaining IP65 rating
  2. Series Mounting: Dual end terminal block modification allows daisy-chain connection up to 12no. light fittings.
  3. Emergency: Nasmyth is compatible with the Elgin series, which is a plug and play 3W non-maintained, self test - 3 hour integrated emergency module. Remote testing functionality can also be achieved by installing an emergency key switch on the permanent live
  4. Sensor: The Nasmyth Series has optional modification to provide microwave sensor controls. The microwave sensor it provides control over the settings: detection range, delay time, waiting time, waiting brightness and light sensor value. These can be configured and applied to up to 4 individual scene modes.
