Purpose
• HPS is the current gold standard for greenhouse or sole source farming.
• LED technology has rapidly advanced to surpass traditional technology in
the horticulture industry.
• Currently many LED horticulture fixtures underperform due to inefficient
LEDs and poor system design: optical, thermal, and electrical design.
• This reference design showcases designing with the world’s most efficient
LEDs (XP-G3 and XP-E) to meet HPS performance at half the wattage.

Equivalent PPFD on a 4x4’ plot at half the wattage of an 1000W HPS solution
Effective use of secondary optics to achieve equivalent light uniformity
Full spectrum lighting matching that of HPS
Effective use of LED system design to enable passive cooling
– No active cooling fan compared to majority of the LED fixtures on the market
• Use off-the-shelf parts for assembly
• Modular design
• IP65+ rated

Spectral Distribution
More Violet/Blue was introduced to the reference design intentionally as customers
using HPS have preferred more of a balanced spectrum.
The recipe can be fine tuned to any manufacturer specifications.

Simulated PPFD Plots
Comparison between Gavita at 1m (min distance) to:
• Reference Design
• Typical LED replacement with spot optic
• Typical LED replacement without optics
Target comparators:
• PPFD AVG, PPFD Uniformity (min to max ratio)
• 4x4’ plot at manufacturer recommended height
• 100x100 points on the entire 4x4’ plot (10,000 points)
– Displayed on the right is a dizzying amount of points calculated on a 4x4’ plot
