INDO launches TopLink for commercial glasshouses
A driverless LED top light in 400W, 600W and 800W, up to 2,550 micromoles per second, with nothing above the crop that needs replacing at eight to ten years.
INDO has launched TopLink, a new LED top light for commercial glasshouses, built in the UK on the same Direct Drive architecture as the rest of the range.
Nothing to replace above the crop
The argument is the one INDO has made on the roads for years, applied to a glasshouse roof. In a conventional fixture the driver is the component that goes first, and in a glasshouse that means access equipment over a growing crop.
Conventional drivers start failing at eight to ten years. TopLink has none, so there is nothing to replace above your crop.
