Horticultural COB LEDs

Hailux Lighting’s horticultural chip-on-board (COB) LEDs which use the industry’s most advanced phosphor formulations to optimize spectral characteristics were developed to deliver industry-leading high PPF performance in the ‘plant growth essential’ wavelengths of 380nm to 750nm:

  •    380nm to 400nm, UV
  •    400nm to 750mm, Hailux HPS Spectrum
  •    500nm to 600nm, Blue
  •    600nm to 750mm, Amber/Red/Near IR

Designed for use in Horticultural Grow lights, these COB LEDs can be used in combination with each other to mirror the spectral distribution of the McCree Curve for the most productive plant growth.

Each Horticultural COB LED is adjustable and can be dimmed, independently of each other, to adjust the ratio of each light color, as needed for each phase of a plant’s growth cycle.

Block Diagram

The diagram below depicts the TG Series of Horticultural COB LEDs connected to an LED Driver (LED Power Supply), which can be either Dimming or Non-Dimming.

Hailux Lighting recommends the use of a Constant-Current Driver for optimum product performance.

Internally, the TG-40 Series has ten diode strings, connected in parallel, with each string comprising 12 LED chips connected in series whereas the TG-10 Series has four parallel strings, with each string being 10 UV-diode chips connected in series.
