Products Description
In order to meet customers' requirements for different grow stands, we have developed a higher power Indoor LED Grow Light 800W R42 Spectrum. This fixture consists of 8 separate bars. The power of each bar is 100W. If the customer needs an Indoor LED Grow Light of about 600W, then the fixture can be changed to 6 bar; if the customer needs higher power, such as 1000W and 1200W, they only need to increase the number of Bars, and of course the LED driver must keep up.
The PPFD Map of AC800
PPFD measures the number of photons emitted over one square meter per second, measured in µmol/㎡/s(micromoles per square meter per second). This is usually the number shown to you on a handheld PAR meter. PPFD is the most important number to growers because it shows the average light level on your growing space.
In a 2010 study on the PPFD values required for cannabis, it was found that a value between 1,500 and 2,000 was best for growing cannabis indoors. However, this optimal range is not common among commercial grow lights because it consumes a lot of power and is very expensive to run in the long term. Therefore we use a lower intensity grow light which is enough to produce a high yield.
1. 200 to 400µmol/㎡/s PPFD can successfully grow seedlings, clones and mother plants;
2. In the vegetative growth stage, 400 to 600µmol/㎡/s PPFD is sufficient;
3. Flowering plants need strong light of 600 to 900µmol/㎡/s.
Our Indoor LED Grow Light 800W R42 Spectrum can perfect match the requirement of the cannabis different growth stages.

Key Feature
High light efficiency and spectrum optimization upgrade
R48 spectrum scientific enhancement
Spectral coverage: 380-760nm full spectrum design, accurate simulation of natural light environment, 660nm red light proportion increased to 48% (industry standard is usually 30%-35%, R42 is 42%), further activate photosensitive pigments (such as phytochrome A/B), significantly accelerate the photomorphogenesis during flowering period.
THC and yield increase verification: third-party laboratory data show that in the cultivation of crops (such as cannabis) using R48 spectrum, the THC content increased by an average of 15%-18%, and the yield per plant increased by 20%-22% (compared with traditional HPS spectrum).
Dynamic spectrum adaptation: Support UV/IR enhancement module (customization required), which can flexibly adjust the spectrum ratio for different growth stages (such as vegetative period, flowering period) to achieve precise stage-by-stage regulation.
Improved spectral stability: After 10,000 hours of continuous operation, the spectral shift rate is <1.0% (R42 is <1.2%, industry average >3%), which provides better long-term planting consistency.
Photon efficiency and chip technology enhancement
Samsung LM301H EVO chip: quantum efficiency (QE) increased to 3.0 µmol/J, PPF output stabilized at 2850 µmol/s, and power conversion rate increased by 5% compared to R42.
Energy consumption comparison: Compared with traditional 1000W HID lamps, 800W R48 LEDs reduce energy consumption by 55% at the same light intensity, and the annual light decay rate is <2.5% (HID lamps have an annual light decay of about 15%).
Triple redundant drive design: Each chip is equipped with an independent circuit, and a single point failure does not affect the overall operation, and the system availability rate reaches 99.95%.
Industrial-grade durability and enhanced protection
Materials and heat dissipation upgrade
Aviation-grade 6063-T6 aluminum alloy shell: thickness increased to 3.0mm, anodizing process improves corrosion resistance by 50%, suitable for extreme humidity environments (such as tropical greenhouses).
Seismic performance: passed the MIL-STD-810H standard vibration test (5-2000Hz), suitable for maritime and high-seismic zone deployment.
Intelligent control and multi-scenario adaptation
Daisy Chain 2.0 technology: supports RJ11 + wireless networking, a single controller can connect multiple lights in series, compatible with 0-10V/PWM/DALI protocols, and adaptable to Priva, Argus and other systems.
Multi-layer independent control: In the vertical farm scenario, each layer can set the light cycle independently (such as 20/4 hours on the top layer and 12/12 hours on the bottom layer), and the PPFD uniformity is >92%.
Energy saving and economic advantages
Annual electricity cost comparison (12 hours/day, electricity price $0.12/kWh):
800W R48 LED: 3,360 kWh / $403.2
1000W HPS: 4,380 kWh / $525.6
Annual savings per lamp: $122.4 (16% increase compared to R42)
Certification and service guarantee
Global certification: UL 8800, DLC 5.1, CE and ENEC certified, in line with EU Ecodesign 2027 energy efficiency standards.
Light decay warranty: Free replacement of light source module within 5 years if PPF output is 90% lower than the initial value.
AI light recipe support: Provides preset spectral templates based on crop types (such as cannabis, tomatoes, orchids), which can be switched with one click through the App.
Practical application cases
CannaTech Laboratory (Canada):
After using the R48 spectrum, the cannabis yield increased to 1.5kg/m², the THC content reached 28%, and the electricity cost was reduced by 52%.
Netherlands Flower Base:
The rose flowering period was shortened by 7 days, and the flower color saturation (ΔE) was increased to <1.5, which meets the high-end market standards.
FAQs
Q: What is the best spectrum to use when growing cannabis? Does an optimal spectrum exist?
Cannabis plants respond well to both blue light and yellow/red light. Blue light is at the lower end of the spectrum, which we are used to calling "cold colors" in life, while yellow/red light is warmer in our eyes.
Let's get outside and look at the solar spectrum throughout the year.
In the summer, when the sun is high and the sky is very bright, blue light will be most prominent. Marijuana plants will grow stronger when using grow lights with a higher ratio of blue light. Blue light range is 400-500 nm, ideal value is 460 nm.
Red light during flowering will result in higher yields. Warmer light can be seen later in the year, when the sun is lower in the sky and not as bright. Cannabis plants notice this as a sign of beginning flowering, so grow lights with a higher amount of red light content are best for the flowering stage. The range of red is 620 to 780 nm, ideally 660 nm.
In summary, using an accurate spectral map does not determine crop success or failure. Most grow lights on the market today will include enough blue and red light to take plants from seedling to harvest without issue. If you prefer your plants to be taller and have more space between nodes, you can use warmer grow lights during the vegetative stage. There are also recent studies claiming that red light is actually more beneficial to plants because blue light drives photosynthesis less efficiently.
Our Indoor LED Grow Light 800W R42 Spectrum is the perfect for the growth of the cannabis.It is very popular in the market.
Q: Can the R48 spectrum be customized for different crops?
A: Yes! The R48 supports dynamic spectrum adjustment via an optional smart controller. You can fine-tune red (660nm), blue (450nm), UV, and IR ratios through our mobile app to match specific growth stages (e.g., higher blue for leafy greens, enhanced red for flowering).
Q: Does the light degrade over time?
A: With Samsung LM301H EVO chips and active cooling, annual light decay is <2.5% (vs. 15% for HPS). A 5-year warranty guarantees free module replacement if output drops below 90% of initial PPF.
Q: How much power does the 800W R48 actually consume?
A: Actual power consumption ranges between 760-790W. Compared to a 1000W HPS lamp, it saves 55% energy at equivalent light intensity, reducing annual electricity costs by up to $122.4 per lamp (at $0.12/kWh).
Q: Is it suitable for high-humidity environments?
A: Yes. The IP66-rated housing, 3.0mm aerospace aluminum shell, and corrosion-resistant coating withstand extreme humidity (e.g., tropical greenhouses).
