Adura Launches LED Modules for Horticulture

Adura LED Modules for horticultural applications

Light-engine manufacturer Adura LED Solutions of Orange County, California has introduced two new LED modules aimed at horticultural solid-state lighting (SSL) applications.
The modules feature Cree LEDs, LEDil optics, and metal core printed circuit board technology that was invented by a company called Sinkpad. The thermal technology elements, known as Sinkpad II, enable passive cooling.

The LED die include a combination of phosphor converted white LEDs and red LEDs to maximize photosynthetic photon flux (PPF). PPF is a metric that is unique to horticultural lighting based on the spectrum of light radiation that activates photosynthesis. The modules apparently employ Cree’s latest photo red LEDs.

Adura has created the modules so that makers of horticultural lighting can quickly bring such products to market. The modules have either a square (1966-GLA) or a rectangular (1950-GLA) form factor built around the SinkPad II metal-core printed-circuit board (MCPCB) technology.

The 1966-GLA provides PPF of 56.22 µmoles/s (micro moles per second) while consuming 30W and the 1950-GLA offers 54.06 µmoles/s using 33W. The square 1966-GLA draws 1000 mA at 34-37 Volts and provides 3811 lumens for an impressive 115.9 Lumens Per Watt (LPW). The rectangular 1950-GLA is even more efficient, drawing 700mA with a forward voltage of 43-46V it produces 3619 lumens for 122.2 LPW.

According to Adura, the modules deliver a spectrum distribution that is very conducive to plant growth. The spectral distribution features energy peaks in the blue and red regions that correspond to peak chlorophyll absorption, thereby optimizing photosynthesis. The blue energy peak comes from the blue emitter which emits white light with the help of a phosphor. The red peak originates from the integrated Cree Photo Red LEDs.

“The Grow Light modules deliver dramatic power savings and unmatched product reliability compared to older generation of Grow Light technologies. The modules offer low-power, high-efficiency, best-in-class thermal performance using Adura’s patented SinkPad II MCPCB Technology, homogenous light distribution at precisely the right wavelengths, and color ratios needed for superior photosynthetic response,” said Abdul Aslami, director of sales and marketing at Adura LED Solutions. “In horticulture application, LED lighting is most effective when the spectrum and level of the light are exactly tuned to the particular crop and growing conditions.”
