McCree Series PRO-LED^TM Grow Lights | HPSH Series PRO-LED^TM Grow Lights

PRO-LED^TM Series of LED-COB Grow-lights

The PRO-LED^TM Grow-lights are fixed spectrum lights, with an 85% ~ 95+% match to the McCree Curve, or with HPS Helper spectrum, depending on the COB selected. The PRO-LED^TM series also has a close match to Sunlight (except the HPSH) according to model selected (see spectrum graphs). The PRO-LED^TM lights have passive cooling, with your choice of 60°, 90°, or 120° borosilicate glass lenses with silicone seals, and are IP54 (water proof).
The PRO-LED-100W lights are ideal for seedlings/cloning areas, small grows, as supplemental lighting, or as your main top-lights. Give your plants the light they need to grow and thrive with the PRO-LED Series.

Anatome of a PRO-LED Grow-light

There are presently two series available:
The McCree series that offers matches of 85%, 90% and 95+% to the McCree curve - McCree Series, and
The HPSH series which is fitted with the High Pressure Sodium Helper COB that provides supplementary light - HPSH Series


McCree Series PRO-LED^TM Grow Lights
	The PRO-LED^TM McCree Series LED Grow Lights, are a professional grow-lighting fixture with premium MeanWell HBG-100 series UL and CE approved drivers, over-spec passive heat-sinks, and high quality borosilicate glass lenses, using the Mc85, Mc90, or Mc95+ COBs. The spectrum of the lights are based on the latest scientific research and utilises the ELPL-MC COB series, which have a 85% to 95+% match to the McCree Curve, and an 80+% match to sunlight. The PRO-LED^TM LED Lights are designed for the rigors of high-humidity Greenhouse environments. They are water resistant (IP-54) and have no fan as they are a passively cooled light (convection cooling), and they are made from durable, rust resistant, powder coated. aircraft grade aluminum for a long lifespan.

Mc SERIES LED COBs
The PRO-LED^TM LED Grow Lights are equipped with the 100 Watt ELPL-Mc Series COBs, which are based on the latest scientific research. They are unique as the Mc series are the world's first LED COB series to offer an 85% to 95+% match to the McCree curve depending on the model of COB selected (see What Light Do Plants Need?)
They can be used in groups (with 7 or 8 PRO-LED lights [700W~800W] replacing one 1,000W HID light) for commercial scale growing saving over 25%~35% in energy costs.

SPECTRUM
The McCree curve is the spectral curve that scientists have determined is the best for growing a variety of crop plants. Our PRO-LED^TM lights have an 85~95+% match to the McCree curve - see spectrum charts below. For details, specifications, and larger versions of the spectrum charts of the ELPL-Mc series of COBs, see the COBs for Growing Plants page.
The extra UV and blue light (compared to most grow-lights) provided by some models of the Mc series of COBs (especially the Mc90 and Mc95+ COBS) spectra are ideal for applications such as growing leafy green plants (lettuce, kale, spinach, arugula, etc.,), herbs (parsley, rosemary, basil, cilantro, etc.,) and for germination and cloning of Cannabis plants. UV light is also a major contributor to the production of resins in Cannabis plants. The plethora of red light in the spectrum insures that these lights are also ideal for growing all types of flowering and fruiting plants.

COMPARISON GRAPHS
Here are comparison graphs, from our plant/grow light spectrometer, measured in PPFD (PAR)*, which show a comparisons of the various Mc series of 100W COBs (Mc85, Mc90, and MC95+) spectra, to various standard curves for Chlorophyll A, Chlorophyll B, and Beta Carotene - the light absorbing compounds in plants responsible for growth. The PRO-LED^TM Grow Lights match to these curves is very close due to the ELPL-Mc series of COBs careful construction, and the use of our self-developed and proprietary phosphor coatings.

ADVANCED LED AND DRIVER TECHNOLOGY
The PRO-LED^TM McCree series of LED grow-lights are built with the most advanced, proprietary, LED technology to insure maximum output, a close match to the McCree curve spectrum, long service life, and maximum energy savings.
The drivers are premium quality, MeanWell brand HBG-100 series, with a metal case, and with universal (100~300VAC, 50/60Hz) power input, thus they can work almost anywhere in the world. (Higher input voltage models, and models with DALI are optionally available.) The drivers are also IP65 rated, CE and UL approved, and come with a 5 year warranty.

PASSIVE COOLING AND RUGGED CONSTRUCTION
The housings of the PRO-LED^TM LED lights are carefully designed, with internal heat-pipes and large heat-sink fins for effective passive cooling of a 150W COB, even thought they are only equipped with 100W COBs. There is 50% more cooling capacity than needed - this means no noisy, high maintenance fans. With an IP-54 water and dust proof rating, they are well suited to the high humidity conditions found in greenhouses.

MAXIMUM ENERGY AND MAINTENANCE SAVINGS
The PRO-LED^TM LED lights can save 25% to 35%, and often more, in energy costs compared to conventional metal halide or high-pressure sodium grow lights. They also save time and money on maintenance as the annual bulb changes required by typical conventional lights is not needed anymore.
These savings are available while providing a perfect spectrum with a close match to the McCree curve and the spectrum of Sunlight, with an increased crop yield due to the additional wavelengths of light that are not available from the typical LED or HID grow-lights.

We recommend the 60° lenses for greater hanging heights (46cm - 18" to 61cm - 24"). Other beam-spread lenses (45° and 120°) are optionally available.

PRO-LED-100 McCree Curve Grow-light PAR/PPFD Readings

*PPFD: Lighting for plants is different from lighting for humans. Light energy for humans is measured in lumens, with light falling onto a surface measured as illuminance with units of lux (lumens per square meter) or foot-candles (lumens per square foot). Light energy for plants on the other hand, is measured as photosynthetic Active Radiation (PAR), with light falling onto a surface measured as photosynthetic photon flux density (PPFD). Lumens are for humans - PPFD/PAR are for plants!


HPSH Series PRO-LED^TM Grow Lights
	The PRO-LED^TM HPSH Series LED Grow Lights, are a professional grow-lighting fixture with premium MeanWell HBG-100 series UL and CE approved drivers, over-spec passive heat-sinks, and high quality borosilicate glass lenses, using the HPSH (High Pressure Sodium Helper) COBs. The spectrum of the lights is intended to be used with HPS lamps to add the UV, Blue, Deep Red and Infra Red that are lacking in the typical HPS lamp's spectrum. When 4 pieces of PRO-LED-100-HPSH lights are added to a 1,000W HPS lamp (the recommended configuration), the combined spectrum of the lights is much improved. The PRO-LED^TM LED Lights are designed for the rigors of high-humidity Greenhouse environments. They are water resistant (IP-54) and have no fan as they are a passively cooled light fixture (convection cooling), and they are made from durable, rust resistant, powder coated aircraft grade aluminum, for a long lifespan.

HPSH SERIES LED COBs
The PRO-LED^TM LED Grow Lights are equipped with the 100 Watt ELPL-HPSH Series lights are designed as as a low cost supplemental spectrum to HPS lamps. These are the world's first COBs designed specifically to add UV, Blue, Deep Red and Infra Red light to the spectrum of High Pressure Sodium lamps, which are typically lacking in these areas of the spectrum.
The recommended configuration is 4 pieces of PRO-LED-100W-HPSH lights to each 1,000W HPS lamp (40% HPSH output) for commercial scale growing. The ratio of HPSH PRO-LED lights can be increased or decreased according to the needs of the crop.

SPECTRUM
While the McCree curve is the spectral curve that scientists have determined is the best for growing a variety of crop plants, HPS lamps are nowhere near a close match to the McCree curve, yet they still remain popular as grow-lights. This may be because people have been growing with them for years and are used to them, or because they are cheap and easy to buy, even though they are wasteful of energy (compared to LED lamps).

The ELPL-HPSH COB Series of light-engines has an unusual spectrum, as it is designed as a supplementary light to add to a High Pressure Sodium light. Note that the HPSH light emits UV in the 390~410nm range, abundant blue light in the 410 ~ 470nm range (with a peak at 440nm), some Orange light from 590~630nm, abundant Red light from 620~700nm, and strong Far Red and Infra Red light output from 700~780nm (with a peak at 735nm). These are all wavelength which the HPS lamps do not produce, or which they produce weakly with insufficient light for the plant's needs, especially flowering plants - which can be boosted by the HPSH lights.
This spectrum (right) shows the output of a popular 1,000 Watt High Pressure Sodium grow-light. Note that it produces almost no UV light, and only miniscule amounts of Blue light. While the HPS light does produce some red light in the 620~700nm orange to red range, the red light output falls off rapidly around the crucial 660nm wavelength and the HPS light produces almost no Infra Red Light (700~780nm). This lack of UV, Blue, Far Red and Infra Red light is less than ideal for growing plants, especially flowering plants which need additional Red light, and take advantage of the 'Emerson Effect' when IR light is available to the plants.
The spectrum on the right shows the results when combining the recommended 4 pieces (400W) of HPSH COB lights with a typical 1,000 Watt HPS Lamp. The effect of the HPSH lights can be increased by adding 6 HPSH COB lights (600W), or the supplementary effect can be decreased by adding only 2 HPSH COB lights (200W). You will note that there is now an increase in the UV and blue light in the 390nm to 490nm range, as well as a slight increase in green light, an increase in Red light around the 630~680nm range, and a large increase in Far Red light in the 720nm to 755nm range, so that flowering plants can take advantage of the 'Emerson effect', which increases photosynthesis.

HPSH Comparison Graphs
The graphs (below), from our plant/grow light spectrometer, measuring in PPFD (PAR)*, shows a comparison of the ELPL-HPSH 100W COB spectrum, to various standard curves for Chlorophyll A, Chlorophyll B, and Beta Carotene - the light absorbing compounds in plants responsible for growth. These graphs are not particularly useful as the HPSH COBs/Lights are intended as supplemental to HPS lamps.

The PRO-LED^TM LED lights can save 25% to 30%, and often more, in energy costs - they also save time and money on maintenance as the annual bulb changes required by typical conventional lights is not needed anymore.
These savings are available while providing a supplementary spectrum with additional UV, blue, deep red and Infra Red light to enhance your HPS lamps. This gives you an increased crop yield due to the additional wavelengths of light that are not available from the typical HPS grow-lights.
