Every design decision, every component choice, every test result.
This is how we built the most efficient full-board LED grow light.
Three rigid panels connected by hidden hinges. Folds to 40% of its shipping volume. Unfolds in seconds — no tools required. The first full-board panel that actually fits in a closet.
Current pre-production renders of the Eclipse 328. Final production unit may vary.
White LEDs with 3.28 μmol/J efficacy. Industry-leading efficiency, paired with OSRAM 660nm Deep Red for enhanced photosynthetic response.
99% uniformity across the entire surface. No strip gaps, no hot spots, no light spill. Every leaf gets the same PPFD.
400-600 W/m·K thermal conductivity. Covers the entire backplane. Passive cooling — no fans, no noise, no dust.
Commercial-grade Mean Well driver. IP65 rated for humid grow environments. >92% efficiency for minimal energy loss.
Sunrise/sunset simulation, spectrum tuning, multi-unit orchestration (up to 10+ boards), OTA firmware updates.
Commercial-grade reliability backed by a 5-year warranty. IP-protected driver, sealed LEDs, corrosion-resistant materials.
"We're not a marketing company that happens to sell grow lights. We're engineers who believe better light grows better plants. That's why we show you the data, the design, and the decisions — not just the claims. Judge Eclipse 328 by what it is, not by what we say about it." — K99 LABS Engineering Team
