The Future of LED Horticultural Lighting: Beyond Samsung LEDs
Samsung LEDs have long been a benchmark in horticultural lighting and are widely used in high-performance grow lights. However, as Samsung gradually shifts its focus away from this segment, the horticultural lighting market is entering a period of transition, and Samsung-based LED grow lights are gradually phased out of the market.
For growers, the main issue isn't losing Samsung's high efficiency, but deciding what to choose next.
Why Samsung LEDs Withdrew from Horticultural Lighting
Samsung's exit from garden lighting is primarily driven by strategic and industry-level changes rather than product performance.
Industry Restructuring
The LED and semiconductor industry has been consolidating. Companies are streamlining product portfolios and focusing on higher-growth areas such as automotive lighting, microLED, and AI-related chips, while reducing exposure to smaller niche markets like horticultural lighting.
Business Focus Shift
Samsung Electronics has increasingly directed R&D and production toward higher-value applications, including display technologies and automotive solutions. Compared to these priorities, horticultural LEDs represent a relatively small and less strategic segment.
Rising Price Competition
The horticultural LED market has become highly price-competitive due to mass adoption and low-cost manufacturing expansion. As performance differences between chip suppliers narrowed, profit margins declined, making the segment less attractive for premium manufacturers.
Key Evaluation Criteria for Alternatives
Efficiency
The Samsung LM301 series has long been a benchmark in horticultural lighting due to its high efficiency, typically reaching around 2.7–3.14 μmol/J. A suitable alternative should achieve a comparable level of efficacy.
Spectrum
Full-spectrum lighting is essential for mimicking natural sunlight and supporting all growth stages. In addition, specific wavelengths should be optimized, particularly red light, to promote flowering effectively.
PPFD
PPFD is a key metric in horticultural lighting. A qualified alternative must provide not only high efficiency but also stable and uniform PPFD, ensuring even light distribution so that all plants receive consistent intensity for optimal photosynthesis.
Reliability
A qualified alternative should possess stable performance. It should have a slow light decay rate and a long lifespan to maintain stable light output even in long-term use.
Value
While LM301 chips are relatively expensive, their efficiency and durability lower long-term costs. A strong alternative should provide better overall value, with a more reasonable upfront price while maintaining equal or lower operating costs.
A true alternative is not just comparable, but exceeds the LM301 series in certain aspects.
Mainstream LED Alternatives
The LED horticultural industry is shifting from chip-centric efficiency to system-level performance optimization. Today, most solutions focus on balancing efficiency, spectrum design, and cost.
Bridgelux LEDs
Bridgelux is a widely used supplier in horticultural lighting. Its horticulture-grade solutions typically achieve around 2.5–2.8 μmol/J system efficiency, depending on overall fixture design and thermal control. With LM-80 lifespans exceeding 50,000 hours, Bridgelux is valued for its balance of efficiency, cost, and reliability.
Seoul Semiconductor LEDs
Seoul Semiconductor offers white and horticulture-focused LEDs, including SunLike-based full-spectrum solutions. In real applications, system efficiency is typically 2.3–2.8 μmol/J, depending on fixture design. Their key strengths are spectral quality, color consistency, and long-term stability.
San’an Optoelectronics LEDs
San’an’s modern high-binned white LEDs reach 150–220 lm/W equivalent performance, with horticultural fixtures typically achieving around 2.0–2.7 μmol/J depending on system design. Its main advantages are cost efficiency and large-scale production capability.
Osram LEDs
Osram specializes in high-performance spectral LEDs, especially deep red (660 nm) OSLON Square chips, which can reach 4.0–4.6 μmol/J under optimized conditions. These are not full-spectrum LEDs but are widely used to enhance flowering when paired with white light sources.
Among these new-generation solutions, one type of LED is being adopted by an increasing number of brands.
Representative Next-Generation Solution: Bridgelux LEDs
Bridgelux LEDs are a new generation of system-level horticultural lighting solutions that are being adopted by an increasing number of grow light brands. Rather than focusing solely on chip performance, they emphasise full fixture optimisation. Currently, well-known brands' grow lights using Bridgelux LEDs can achieve high performance; Mars Hydro is an example of this.
High Light efficacy: 2.8–2.9 μmol/J system efficiency, approaching high-end LED performance levels
Optimized spectrum: Full-spectrum design with added red and far-red wavelengths to better support plant growth stages.
More cost-effective: More reasonable pricing compared to premium chip-based solutions, offering higher overall cost-effectiveness.

Industry Trend Shift
The LED grow light industry is moving toward system-level optimization. Instead of focusing only on peak diode efficiency, modern designs prioritize a balance of efficiency, spectrum quality, and cost. Many new models are already adopting these system-level solutions to achieve better real-world growing performance and higher overall value.
The transition away from the LM301 era does not represent a decline in lighting quality, but rather a shift toward more optimized and cost-efficient system design. The future of horticultural lighting is defined not by a single brand, but by integrated performance and improved engineering efficiency.
