LED Toplighting Bar

Passively cooled toplighting laid out to a DLI target and a uniformity figure.

A passively cooled horticultural LED bar specified by daily light integral and canopy uniformity rather than by installed wattage per square metre.

  • Dimmable 0 - 100 % with no measurable spectral shift
  • Passive extruded aluminium body, no fans to service
  • Layout calculated to a target DLI and >90 % uniformity
  • Hybrid operation alongside existing HPS installations
  • Photometric file supplied for independent verification

Indicative lead time: 10 - 12 weeks

Wattage is not a specification

Asking for “150 watts per square metre” describes an electricity bill, not a crop response. Photosynthesis responds to the daily light integral reaching the canopy, so that is where our layouts start: your latitude, your glazing transmission, your screen schedule and your target DLI produce a fixture count and a hanging height. Installed wattage is an output of that calculation, not an input.

Uniformity decides the weakest row

A compartment averaging the right light level while varying ±25 % across the floor will be harvested at the rate of its darkest bays. Every GreenGrow lighting plan is delivered with a calculated uniformity map and we design to better than 90 % across the cropped area.

Living with existing HPS

Few growers replace an entire lighting installation at once. The toplighting bar is designed for hybrid rows, sharing an existing suspension grid and control group with HPS fixtures so a site can convert compartment by compartment as budget allows.
