Accelerating our transition to a balanced food system

For people and our planet

 

Libra Design was founded on a single belief

Controlled-environment agriculture (CEA) is fundamental to solving our greatest challenges from the climate crisis and biodiversity loss to global food insecurity

Bespoke horticulture lighting systems designed (and priced) for commercial farmers

 

Designed to your requirements

Our engineers and lighting specialists work with your team to develop a horticulture lighting system as unique as your farm. From PPF and PPE to HLPD and SQD, we ensure every specification is tailored exactly to your business, cultivation and operational strategy.

Priced to your budget

Our transparent, function-based pricing model ensures you pay only for what you need. Coupled with our bespoke design process, the result is a horticulture lighting system perfectly suited for your farm with significant cost savings compared to off-the-shelf LED systems.

Technically speaking…

  • $0.18/PPF

    Dollar-per-photosynthetic photon flux (PPF) is not a great metric to assess a lighting system in isolation, but when considered along with other key variables, it provides a shortcut to quickly determine value. With systems starting at $0.18/PPF (delivered), we aim to break the “expensive = good” stereotype.

  • 3.0 PPE

    The typical horticulture lighting system we design achieves a photosynthetic photon efficacy (PPE) of 3.0 µmol/J (58% higher than the requirement for DLC Hort QPL).

  • 200 - 2,000+ PPFD

    We customize our LED modules to achieve any photosynthetic photon flux density (PPFD), from 200 µmol/m²/s for low-DLI crops like microgreens to the most light-loving sativas requiring up to (and beyond) 2,000 µmol/m²/s.

  • ∞ SQD

    Every lighting system we design includes a customized spectral quantum distribution (SQD) specifically tailored for our clients’ needs with biological, operational and economical needs taken into consideration.

  • <1"

    Our mid-flux LED module is specifically designed for dense vertical farming applications. With a form-factor less than one inch thin, we provide ample flexibility for you to increase crop volume and maximize air flow between layers.

  • AC/DC

    Our LED modules are compatible with both conventional LED drivers and direct to DC for onsite power generation and remote power distribution systems.

  • Uniformity

    Light uniformity is critical to the success of a harvest, from crop consistency to overall yield. Our goal when designing your horticulture lighting system is to ensure your crop canopy receives uniform PPFD from the center to the edge.

  • ±5% Tolerance

    We guarantee the performance of your horticulture lighting system within ±5% of the target specification as verified by a Nationally Recognized Testing Laboratory (NRTL).

Our technology

Removing barriers to an equitable future

Our mission is to create a balanced food system for people and our planet by removing the financial and technological barriers to CEA.

Moving forward by giving back

We are a proud business member of 1% For The Planet where a percent of every Libra sale goes to addressing our planet’s most pressing issues from deforestation and the climate crisis to food waste and food insecurity.
