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 leading horticultural lighting supplier, offering solutions with system efficiencies of 2.7–2.9 μmol/J, depending on fixture design and configuration. With LM-80 lifespans of over 50,000 hours, Bridgelux LEDs are highly regarded for their combination 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, particularly 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.
Representative Next-Generation Solution: Bridgelux LED Lights
Bridgelux LEDs are a new generation of system-level horticultural lighting solutions that are being adopted by an increasing number of grow light brands. The following is a comparison between the Bridgelux 3030 and the Samsung EVO：

Light Performance
The Bridgelux 3030 and Samsung EVO LEDs have very similar light spectra across the 400–700 nm range, with peaks at 450 nm and 660 nm. Their comparable light efficiency ensures that, at equivalent power input, the difference in PPF is minimal. Because both the spectral composition and light efficiency are nearly matched, the difference in final plant yield under identical growing conditions is less than 5%.
Both LEDs have long lifespans, with LM-80/TM-21 testing showing lumen maintenance above 50,000 hours. Bridgelux 3030 also exhibits slightly lower early-light decay than its own projections. Overall, the data indicate that the two LEDs perform similarly for horticultural use.
Cost Performance
The Bridgelux 3030 stands out for cost performance. They are less expensive than Samsung EVO LEDs, which reduces the upfront cost of grow lights. In addition, they consume less electricity, further lowering operating costs.
For example, consider a 1000 W grow light running 12 hours per day, with electricity priced at $0.11 per kWh. The annual electricity cost is calculated as:
Annual Cost ($)=Power (kW)×Hours/day×365×Price($/kWh)
=1×12×365×0.11≈$481.80
Bridgelux 3030 consumes 8–12% less energy than Samsung EVO:
Annual Savings ($)=481.80×0.08=$38
Overall, using Bridgelux 3030 1000W grow light saves at least $38 per year compared to Samsung EVO1000W grow light, with a lower upfront cost.
Brand Reliability
Bridgelux 3030 and Samsung EVO LEDs are both recognized for professional-grade reliability, but they have different strengths. Bridgelux, an established American brand specializing in high-efficiency chips, is praised for stable output, low failure rates, and predictable light decay.
Samsung benefits from large-scale production and rigorous quality control, ensuring consistent performance across batches. Overall, both brands offer durable and dependable LEDs suitable for horticultural applications.
Final Thought
Samsung EVO LED grow lights will remain available for some time, but they are gradually being phased out as chip inventory declines. Next-generation LED grow lights are moving beyond a focus on peak diode efficiency, emphasizing a balanced approach that considers efficiency, spectral quality, and overall system performance.
The best choice depends on your needs. For high-end enthusiasts without budget constraints, Samsung EVO LEDs remain a strong option for now. For commercial growers or those planning for long-term maintenance and future upgrades, Bridgelux 3030 provides a more practical solution.
Mars Hydro's star series, the FC LED grow lights, which originally used Samsung LM301H chips, has been updated with Bridgelux 3030 LEDs. The new version improves actual plant growth outcomes and offers higher overall value. The future of horticultural lighting will be defined not by a single brand, but by integrated system performance and engineering efficiency.
