420 – It’s No Coincidence

For Growers. By Growers

The LED Grow Light Revolution continues with the new High Light 420 plug-and-play system by Grow Lights Australia and LED Teknik.

Designed and manufactured in Australia, the High Light 420 takes indoor horticulture to the next level with 20% more efficiency, a revised spectrum, splash-proofing, and plug-and-play convenience that builds on the legacy of the original High Light.

The original Australian High Light owes its success to being the first true full-spectrum LED grow light – covering the entire PAR range – to run on one channel, incorporating UV and Far Red-enhanced white phosphor LEDs with Australian build quality and reliability.

Grow Lights Australia has taken this original design and improved it with the new High Light 420 boasting unique features not found on other grow lights.

420 top bin LEDs have been used courtesy of a collaboration with LED Teknik – a leading Australian designer of customised horticultural LEDs – and Nichia of Japan, manufacturer of the world’s most efficient mid-power LEDs.

Designed and built in Perth, Western Australia, the High Light 420 is over 3 umol/j efficient with a true full spectrum from 390-780nm. The original High Light UV spectrum has been proven to boost yields and cannabinoids, and the High Light 420 improves on this formula with twice as much Far Red and UV.

An optional water-resistant clear coating is paired with a waterproof loom featuring German LAPP cable, Italian Techno connectors, TE waterproof SlimSeal connectors, and quality Mean Well drivers, making the High Light 420 a modular plug-and-play system with no wiring required.

The new grow light has the same build quality as the original High Light board but is slightly bigger, with LEDs spaced further apart for better heat dissipation. The 420 LED count includes 30 custom UV (405-420nm) and 60 high-powered 660nm Deep Red and 730nm Far Red diodes. The flexible PCB design can swap high-powered diodes in and out to tailor spectra to suit any crop.

The standard Hight Light 420 is designed primarily as a flowering light for short-day species, with testing showing improvements throughout all stages of growth due to the higher levels of Red and Far Red, which is balanced by moderate amounts of Blue and UV to prevent excessive stretch and boost essential oils.

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

The wide light footprint of the High Light 420 provides a uniform plant canopy for even better growth.

These LED grow lights are a genuine HID replacement, but can also be added to existing HPS and CMH lamps to improve efficiency and yields. With up to 50,000 hours of useful life, you’ll never need to change a light bulb again.

The Full Spectrum

Typical white-phosphor LEDs have no UV, low levels of Cyan (470-480nm), more Yellow-Orange than Red, and very little Far Red light.

Grow Lights Australia and LED Teknik have collaborated to produce a light that provides Photosynthetic Active Radiation (PAR) output all the way from 390-800nm on one channel in one of the most efficient LED grow lights on the planet – over 3 umol/j.

No other grow light combines this efficiency with a high Colour Rendering Index (88) and a complete PAR spectrum powered by a single LED driver.

The High Light 420 boosts flowering yields and essential oils without the cost or complexity of supplemental LED lighting because it already contains high levels of Red, Far Red and UV light.
