High Light 420 PAR maps

Each of the following PAR maps is based on the recommended High Light 420 grow light for common grow areas.

The ideal PPFD measurement will vary depending on plant variety and stage of growth, but 800-1,000 PPFD is generally considered ideal for many common types of flowering and fruiting plants. Lower levels of 400-600 PPFD are suggested for leafy greens.

To read the maps, note the red outlined areas that are the individual High Light 420 LED panels mounted to each heatsink. The isolines represent PPFD readings. All calculations are based on an enclosed area with 80% reflective walls.

Typical grow tents have 80-90% or better reflective walls. Flat white painted walls typically reflect 80% of light that hits them. Actual PPFD readings may be higher or lower depending on reflective wall surface, but we’ve found that 80% provides a very accurate estimate for most indoor grow areas with a 5% margin of error.

The above PAR map is for our 250W Mono hanging 50cm (20″) above canopy height in a 0.75m x 0.6m area (2.5′ x 2′). This is a max effort configuration with an average 990 PPFD over the entire area.

This is the same 250W Mono over a 0.8m x 0.8m area (2.7′ x 2.7′) with a nice light pattern and average 800 PPFD. This fixture can light up to 0.9 x 0.9m (3′ x 3′) with an average 700 PPFD

This PAR map is for our 370W Longboard at 50cm (20″) over a 1.2m x 0.6m area (4′ x 2′).

This PAR map is for our 370W Quad over a 0.9m x 0.9m area (3′ x 3′).

This is the same 370W Quad over a 1m x 1m area (3.3′ x 3.3′) with an average 812 PPFD.

This PAR map is for our 500W Quad hung 60cm (24″) over a 1.2m x 1.2m area (4′ x 4′). This configuration is well-suited to single-plant grows.

This is the same 1.2m x 1.2m area lit up by two 370W Longboards hanging 60cm (24″) above the canopy. This configuration provides very even canopy coverage at over 1100 PPFD and is ideal for SCROG grows that fill the entire area.

This is a 1.5m x 1.5m area (5′ x 5′) area lit up by the same pair of 370W Longboards also hanging 60cm (24″) above the canopy. This is the recommended configuration for all areas from 1.2 x 1.2m (4′ x 4′) to 1.5 x 1.5m (5′ x 5′).

For 1.5m x 1.5m (5′ x 5′) and larger areas, two of our 500W Longboards deliver maximum light intensity at 60cm (24″) hang height. This is the recommended configuration for larger areas with supplemental CO2. If high intensity is not required for the first few cycles – but may be desired down the track – the drivers can be dimmed to suit, then turned to full power once CO2 is in place.

The beauty of the new High Light 420 boards is that they are as flexible as your imagination. If you don’t see your configuration here, and are still unsure which kit you need, we can create a custom configuration and PAR map like the ones above to help you decide. Simply Contact Us with your query.
