Horticultural Lighting
Spectrum-tunable LED grow lights that deliver more yield per watt. Engineered with UK research partners, deployed in glasshouses and vertical farms across Europe.
UK universities and research institutions running INDO horticultural lighting, including Cardiff, Rothamsted, NIAB and Birmingham

Completed projects across the UK and Europe
The range
Two platforms, one Direct Drive® technology.
Whether you're lighting a 10-hectare glasshouse or a single-rack research bench, INDO's horticultural fittings share the same driverless architecture: lower running costs, longer lifetimes, and a spectrum tuned for the crop, not the catalogue.
Top Light
High-output overhead fittings for commercial glasshouses and polytunnels. Used by Rothamsted Research, Fairweathers, and Kirton Farm to extend growing seasons and stabilise yield.
Vertical Farming
Slim-profile, low-thermal-load LED bars engineered for stacked-rack indoor cultivation. Tunable spectrums for leaf, root and flowering crops; slot directly into existing rack frames.
Spectrums
Custom spectral recipes engineered in-house and tuned to the specific crop. Delivered as factory-set fixtures or via advanced controls for in-grow adjustment.
TopLink
Our next generation LED top light for commercial glasshouses. Up to 2550 µmol/s from a housing under 10kg, available as 400W, 600W and 800W, fully dimmable over DALI, 0-10V or Bluetooth.
VertiLink
The ultra-thin bar for vertical farming. A wide lens and no shadowing means fewer fittings per rack, and it runs at SELV for safe handling around the crop.
ELEMENT
The Direct Drive® grow light behind our NIAB, Arden Lea and German glasshouse projects. Up to 250,000 hours of life with a 10-year warranty and no driver to replace.

Why INDO
Built for the long crop cycle.
01
Driverless: lower thermal load, longer life
A traditional driver dumps heat into the canopy and fails years before the LED. INDO's Direct Drive® architecture removes the driver entirely. Cooler electronics, longer lifetimes, fewer trip-and-replace cycles in a working glasshouse.
02
Spectrums tuned to the crop, not the catalogue
Spectrums are designed in-house to match each crop, trial protocol, and energy budget. INDO horticultural fixtures are running at Cardiff University, Rothamsted Research, NIAB and the University of Birmingham, where the spectrum gets validated against real research conditions.
03
UK-built, supported in-house
Designed, assembled and tested in Southampton. Lead times are predictable, RMAs are handled directly by the engineering team, and bespoke configurations are quoted on the same call.
