Introducing TopLink, our next generation LED top light for commercial glasshouses

INDO TopLink toplights high above rows of salad leaves in a large commercial glasshouse, pink-red light on the crop

UK made, and built on Direct Drive® so there is no driver to fail. High intensity output from a slim, durable housing that weighs under 10kg.

TopLink brings the Direct Drive® technology we have proven in street lighting since 2010 into the growing environment. Conventional drivers start failing at eight to ten years. TopLink has none, so there is nothing to replace above your crop and no maintenance window to schedule into a growing season.

It is available in 400W, 600W and 800W versions, with red or broad spectrum channels individually controllable and other spectrums available on request. Dimming is fully flexible over DALI, 0-10V or Bluetooth, and both optic and gear are IP66 rated behind a clear glass lens, engineered for year round performance from -40°C to +40°C.

TopLink is quick and simple to install, supplied with hanging brackets, and its slim profile keeps shadowing over the crop to a minimum. Every unit is covered by a 10-year standard warranty, with the option to extend to 15 years.

  • Up to 2550 µmol/s
  • Up to 3.54 µmol/J efficacy
  • <10kg net weight

INDO horticultural lighting runs at research institutions such as the University of Cambridge, Cranfield University and Newcastle University, and at award winning commercial growers such as David Austin Roses. The Direct Drive® technology behind it has been in the field since 2010, with around 500,000 units installed across the UK and Europe.
