High Light 420 LED Board

These individual LED panels must be wired to a driver and preferably mounted to a heatsink or frame. All parts needed can be supplied. Please see our Products Page for the full range.

The new High Light 420 plug-and-play LED grow light continues the legacy of the original High Light.

Designed and manufactured in Australia, the new High Light 420 has 20% better efficiency, a revised spectrum, optional splash-proofing and plug-and-play convenience. It is a “true” full-spectrum grow light incorporating UV and Far Red on one channel (driver).

The original High Light spectrum has proven to boost yields, essential oils and terpenes, and reduce flowering times with the addition of UV and higher levels of Far Red light. The new High Light 420 improves on this design with 420 top bin LEDs from LED Teknik – a leading Australian designer of horticultural LEDs – and Nichia Corporation of Japan – manufacturer of the world’s most efficient mid-power LEDs.

An optional water-resistant clear coating is paired with TE’s SlimSeal connector series for a neat, waterproof wiring solution.

These new boards are slightly longer and more powerful than the old High Light boards and have a more flexible design for customising spectra to suit any crop (on request).

The standard Hight Light 420 spectum is designed primarily for flowering of short-day species, however testing has shown improvements throughout all stages of growth due to the higher levels of Red and Far Red light balanced by moderate amounts of Blue and UV that prevent excessive stretch.

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 oils.

The wide light footprint of the High Light 420 provides a uniform plant canopy for even better growth. The 2:1 ratio means boards can be mounted side-by-side to form a perfect square, or end-to-end for rectangular grow areas. vertical lighting systems – see the HOW TO section at the top of the page.

Suggested Drivers
Grow Lights Australia is an official Mean Well reseller and supplies Australian Approved Mean Well drivers with full warranty. Our prices are among the cheapest in Australia. Please Contact Us if you have any questions about drivers.

High Light 420 boards must not be driven higher than 235W each when used with a matching heatsink, or 135-150W each without a heatsink. If you plan to use a driver that can exceed this wattage you must dim it.
