Exclusively designed and manufactured in Australia, the “High Light 420” series of LED grow panels has been proven around the world to boost yields, essential oils and terpenes – as well as reduce flowering times – with enhanced UVA and Far Red light.

The term “Quantum Board” is often (wrongly) used to describe generic LED grow light panels – these are far from generic!

The High Light 420 Gen3 is the same LED panel that goes into every Grow Lights Australia fixture, so you can now build your own super-efficient ePAR full spectrum LED grow light!

And when we say say “full spectrum LED”, we mean FULL SPECTRUM LED – the closest thing to sunlight indoors.

These LED panels cover the entire ePAR range from 390-780nm, making them ideal for most plant varieties at all stages of growth – particularly shade plants, such as aroids.

With the highest levels of Far Red light in the industry (Far Red = Big Leaves), this latest version has a number of improvements over the previous High Light 420 Gen2.

All Grow Lights Australia horticultural LED panels are water-proofed with a proprietary modified silicon coating that loses less than 1% light output – boosting overall efficiency up to 3.19 umol/j.

The “sun-like” spectrum still features industry-leading CRI95 colour rendition (close to natural sunlight) with 1% UVA and 10% Far Red light, but has a revised colour temperature of 2900-3000K* with an extended blue-violet range.

In-house research has found that ~3000K with additional UVA and Far Red light is the best alround spectrum for general growth, fruiting and flowering of most species – including ornamentals, shade plants, fruits, vegetables and tropical plants.

(We have a new LED Strip design with added blue that covers ~3200K for leafy greens and non-flowering varieties.)

The other major upgrade is the heat and chemical-proof 20AWG (0.5mm) hard-wiring for each panel. This robust wire – made in Australia – gives extra protection against accidental over-current, over-heating and physical handling.

With 420 real top bin LEDs from LED Teknik (Australia’s leading designer of horticultural LEDs) and Nichia Corporation of Japan (manufacturer of the world’s most efficient mid-power and UV LEDs), the High Light 420 spectrum has been refined and engineered to produce the best results with the highest efficiency of any “true” full spectrum LED grow light on the market.

Not all LEDs are equal. Many do not cover the most important spectral ranges below 450nm (UVA and near-UV) and above 700nm (Far Red). “True” full spectrum plant light not only provides better health and vigour, it leads to bigger yields, bigger leaves and shorter flowering times, with documented increases in terpenes and oils.

UVA not only “hardens” indoor plants that would normally be exposed to UV under the sun, it drives secondary metabolite production (essential oils) and regulates root growth. It also prevents inter-nodal elongation (stem stretch due to “shade avoidance”) with high levels of Far Red light.

Far Red (>700nm) works in synergy with Red light (600-700nm) to produce the “Emerson Effect” that enhances photosynthesis. Far Red also reduces fruiting and flowering times as it targets the phytochromes (Pr and Pfr) that regulate photomorphogenesis (physical changes to the plant when exposed to different colours, including the Red-to-Far Red ratio).

The high colour rendition of these LED panels (CRI95) is also an important feature, as horticulturalists benefit from seeing their plants in “true” light to ensure they are not suffering from nutrient deficiencies, disease or pests. High CRI is also easier for the human eye to work under, as it is very close to natural sunlight (CRI100).

The wide light footprint of the High Light 420 Gen3 panel – which is 1.6x larger than traditional “Quantum Boards” – provides a uniform plant canopy, while the 2:1 ratio means each board can be mounted side-by-side to form a perfect square, or end-to-end for longer grow areas.

Despite their high efficiency, High Lights will usually display lower PPFD readings than other LED lights because more than 10% of their light falls outside the traditional PAR range of 400-700nm. This means a 900 PPFD reading under a High Light is over 1000 PFD (photon flux density) when ALL light is taken into account (including UVA and Far Red). Always set your lights 10% lower under High Lights than you would under other LED grow lights for best results.

* CCT increases slightly at higher currents but will be between 2900-3000K
