The P.L Light Systems HortLED TOP light module is a highly versatile solution that offers unrivalled lighting performance and energy efficiency.

Engineered to deliver lighting performance on par with that of traditional light sources, the HortiLED TOP is ideal for use in many different top lighting applications.

Offering unparalleled lighting design flexibility, the fixture is available in multiple distribution and spectral options (see below).

Optional 0-10V dimming allows for seamless integration with compatible control systems. Light output can be dimmed on a relative scale, based on varying levels of natural daylight within the facility — enabling exceptional control of light levels and energy consumption.

A simple plug-and-play platform and intuitive mounting and multiple voltage options allows for quick and easy installation or retrofitting from traditional light sources.

The integrated fins on the top of each module are thermally and mechanically engineered to dissipate heat through conduction and convection paths—minimizing LED junction temperature and maximizing light output, lifetime and reliability

Ideal for lettuces, leafy greens micro greens, and flowering plants such as cannabis, tomatoes, strawberries and floriculture.

The HortiTOP LED module emits up to 860 umol/m2.s with an efficacy of 2.7 umol/J.


Angle Options

The HortiLED TOP is available in two distribution options to deliver optimum light intensity to the surface of the crop. 

  • 80°: With a highly-focused beam pattern, this distribution option delivers exceptional depth penetration into the plants. Ideal for a smaller area, such as a 4' x 4' or 4' x 8' area to deliver maximum light intensity.

  • 150°: Offers exceptional uniformity—enabling wider spacing so growers can achieve desired light levels even across the surface of the crop, with fewer modules. Ideal for a larger area, such as a greenhouse or a warehouse grow to deliver maximum light distribution.

Spectrum options

  • Red/Blue (LB/MB/HB) - for maximum efficiency
  • Red/White (LB/MB) - for maximum efficiency and easy viewing
  • Full Spectrum - for white light viewing, ideal for cannabis grows
  • Custom

        Excellent build quality and performance

        Amazing lights, totally satisfied so far. Efficiency seems on near-miraculous level...finally with this light LED measures up to the hype. Gorgeous made-in-Holland build quality typical of PL, these lights are precision European-made instruments and exude pure quality. The light-bar style does a much better job at even coverage than a single HPS reflector or box-style LED, and the passive cooling rocks, no fan noise.

        Within days of starting these lights up I was giving my old 400w and 600w HPS lamps away to friends. One of these Cannablum spectrum Hortileds has replaced the 600w HPS in my 4X4 tent. I think the Cannablum spectrum would do a good job at veg as well.
