Product Feature
4-Channel Control
Successfully growing lettuce with led lights requires more than just brightness; it requires a precise light recipe. Our dynamic spectrum allows you to adjust the blue and red ratio for different growth stages.
Smart System Control
Supports centralized or zoned group control of grow lights across different areas, with timer and programmable functions.
Dimmable LED grow lights
0–10V dimming capability allows light intensity to be adjusted according to the plant’s growth condition.
IP65-66 Waterproof
IP65–IP66 waterproof rating ensures reliable operation in high-humidity environments.
Optimized Growth through Dynamic Spectral Control
Spectral requirements vary not only among different lettuce varieties but also across each lettuce plant’s developmental cycle. Precise spectral modulation is key to optimizing nutritional profiles—increasing Vitamin C, protein, and soluble sugar content—while minimizing nitrate accumulation. Our LED grow lights feature a fully customizable spectrum, empowering growers to fine-tune light recipes to match the exact needs of different lettuce varieties at every growth stage.
Various Fruits And Vegetables
Our grow lights are not only used for growing lettuce, but can also be used to cultivate other fruits and vegetables. In FY LIGHTING’s grow rooms, they have been widely applied to many different types of plants and have achieved good harvest results.

Spectral Optimization: Precision Light Recipes for Premium Lettuce Varieties
Butterhead Lettuce — Optimizing Tenderness and Nutrient Density
Butterhead lettuce is highly prized in premium salad markets for its silky, tender leaf texture and delicate flavor. To maintain its signature compact, semi-heading shape and increase leaf thickness, our system allows for the precise adjustment of blue light ($450nm$) proportions, effectively preventing plant stretching. Particularly for innovative varieties like Salanova, fine-tuning the light recipe not only preserves its sweet taste but also significantly boosts the concentrations of Vitamin C and soluble sugars.
Romaine Lettuce — Precision Shaping and Enhanced Coloration
The commercial value of Romaine lettuce lies in its upright growth habit and crisp, sturdy central midribs. By utilizing our Red to Far-red ($R/FR$) ratio technology, growers can induce a controlled shade avoidance response to ensure plants grow tall and straight with robust structural integrity. For Red Romaine varieties, we recommend intensifying blue light or UV-A exposure prior to harvest to stimulate anthocyanin synthesis, creating deep purple leaf edges that maximize aesthetic appeal and market premium.
Iceberg Lettuce — Maximizing Density and Food Safety
Iceberg lettuce (Crisphead) requires high water content and a tightly packed,致密 spherical structure. This variety is exceptionally sensitive to light uniformity; uneven distribution can lead to loose heads or physiological disorders such as “Tip-burn”. Leveraging our 17 years of expertise in optical and thermal design, our fixtures provide a highly uniform light field. Combined with dynamic spectral modulation, we can optimize stomatal conductance during the heading stage to ensure high yields while minimizing nitrate accumulation, meeting the strictest international quality standards.

Question: How far should lettuce led grow lights be from the plants?
For optimal growth, LED grow lights should typically be placed 12 to 24 inches (30-60 cm) above the lettuce canopy. This distance ensures a uniform PPFD (Photosynthetic Photon Flux Density) of 200-300 µmol/m²/s, which is the ideal intensity for leafy greens in vertical farming.
Question: How many hours a day should I run led grow lights for lettuce?
Lettuce requires 14 to 18 hours of light per day. Because lettuce is a “long-day” plant, providing consistent light helps it grow faster. However, it also needs at least 6 hours of darkness to prevent physiological issues and ensure healthy respiration.
Question: Can led grow lights for lettuce increase commercial yield?
Yes, professional lettuce led grow lights can increase yield by up to 30-50% compared to traditional HPS lighting. By using a specialized “light recipe,” growers can control the texture, color (such as intensifying red leaf varieties), and nutritional content of the lettuce while reducing energy consumption.
Question: Is growing lettuce with led lights cost-effective for indoor farming?
Yes, it is highly cost-effective due to the high energy efficiency of modern LEDs. Compared to traditional lighting, LED systems reduce electricity costs by 40% or more and generate significantly less heat, which lowers the cooling requirements for indoor or vertical farms.
Question: How can led grow lights for lettuce help prevent tipburn in vertical farms?
Tipburn in lettuce is often caused by localized calcium deficiency due to excessive transpiration or heat. High-quality lettuce led grow lights minimize radiant heat compared to HPS lamps, allowing for a cooler canopy. By optimizing the light intensity (PPFD) and promoting steady transpiration, growing lettuce with led lights ensures more uniform nutrient distribution, significantly reducing the risk of tipburn and increasing the percentage of marketable heads.
