Libra Design creates custom horticulture lighting systems for commercial growers, tailoring LED specifications such as PPF, PPE, HLPD, and SQD to each farm’s operational strategy. Their engineering-driven design and transparent, function‑based pricing deliver solutions that can achieve up to 58% higher photosynthetic photon efficacy than standard DLC requirements, with systems starting at $0.15 per PPF.

Problem
Commercial growers using controlled‑environment agriculture often rely on off‑the‑shelf LED fixtures that are not optimized for their specific crops, lighting density, or energy budget, leading to higher operating costs and sub‑optimal yields.
Solution
Libra Design engineers bespoke horticulture lighting systems that match each farm’s required photosynthetic photon flux (PPF), photon efficacy (PPE), and spectral quantum distribution (SQD). Their function‑based pricing model charges per unit of PPF (starting at $0.15), allowing growers to pay only for the light output they need. The company delivers LED luminaires with efficiencies up to 3.0 µmol/J and customizable PPFD ranges from 200 µmol/m²/s to over 2,000 µmol/m²/s, supporting crops from microgreens to high‑light sativas. By integrating spectrum, power density, and driver compatibility into the design process, Libra Design provides systems that improve yield, reduce energy use, and align with growers’ operational and sustainability goals.
Target Audience
Primary customers are commercial greenhouse operators, vertical farm developers, and indoor cultivation facilities that require high‑performance, energy‑efficient lighting tailored to specific crop portfolios.
Features
- Custom LED modules engineered to meet specific PPF, PPE, PPFD, and SQD targets for each crop and facility
- Function‑based pricing ($0.15 per µmol/s of PPF) that ties cost directly to performance specifications
- High photon efficacy up to 3.0 µmol/J (≈58 % above standard horticulture QPL requirements)
- Flexible form factors: High‑Flux 2.0 units (<10 lb, >2,000 µmol/s) for greenhouse retrofits and Mid‑Flux units (<1 in thick) for dense vertical farms
- Spectrum design covering 400‑700 nm (and beyond) with unlimited customization to match crop genetics and growth stages
- Compatibility with AC‑DC drivers and emerging DC power grids, enabling precise power density control
- Optional branding and aesthetic customization for facility identity
