Close Next Next Proven Result in Hemp Growth Among Different Trial Farms According to USDA’s National Agricultural Statistics Service (NASS) released the results of the 2021 Hemp Acreage and Production Survey in its National Hemp Report. The survey collected data for hemp grown in the open and hemp under protection. Planted area for industrial hemp cultivated in the open for all utilizations in the United States totaled 54,152 acres. The area harvested for all utilizations totaled 33,480 acres. The value of U.S. hemp production in the open totaled $712 million. The value of output for hemp grown under protection in the United States totaled $112 million. The area under protection totaled 15.6 million square feet. ​ ​ With this trend and massive demand for hemp, growers shift their greenhouse and indoor farms to a commercial hemp production base. As the yields and quality of hemp growth are heavily influenced by light intensity – having supplemental or high-quality sole-source lighting systems is critical to maintaining plant health and maximizing cannabinoids content. Light Engine has developed the latest CabLED Grow Light System to support year-round hemp production. ​ ​ In mid-2021, Light Engine has deployed the CabLED grow system in four trial farms, with three indoor farms in Michigan, California, and Washington, respectively, and one greenhouse in Colorado. The system was built with the flexible grow light strip fixed on every edge of the rack. The racks are situated between the hemp, providing a 360-degree light source to favor its growth. ​ ​ The report shows a significant yield increase, with 23%, 31%, and 72% increment in the indoor farms located in California, Washington, and Michigan, respectively, while the result in Colorado greenhouse is still under processing. The difference in increase rate is due to the parameter variations from installation methods. Contact us for full report

English 繁體 简体 PURA-Panel Air-Purifying LED Panel PACO NANOTECH™ filter with UV-C LED Destroys 99.99% of bacteria, viruses and inactivates SARS-CoV-2 PURA-Panel illuminates the space and, in the meantime, provides extraordinary air purifying efficiency while accommodating the sanitizing area’s size, thanks to the sophisticated filtration system. The foam pre-filter traps airborne contaminants and the patented PACO NANOTECH™ filter carries out a purification that eliminates the remaining bacteria, viruses, VOCs (Volatile organic compounds) and odors. Then the air passes through the UV-C light to destruct the DNA and RNA of the micro-organisms, stopping them from reproducing. Finally, the fan outlet releases only fresh and clean air. Pura Panel can suit different ceiling sizes to suit different geographic regions (600x600mm, 625x625mm, 2ftx2ft) without affecting other component sizes. Only the outer flange size will change Be the first to know! Subscribe to get the full product detail and quotation of the PURA Panel. First Name Last Name Email Subscribe Thanks for subscribing!

Close Next Next Customized Spectrum. Optimizing Crops & Yields. Lighting is essential element for plant growth. The most common used spectrum include red (R), white (W) and blue (B) lights are highly active for photosynthesis. The effect of R, W and B spectral components on plant physiology and biochemistry and resource use efficiency were studied during a experiment in a deep cycle hydroponic tray system. ​ The initial experiments were simply to identify the growth characteristics of different species of plants when exposed to the appropriate wavelength for photosynthesis. The study aimed to identify which light format best suited which variety of plant to produce the highest yield. Essentially this was about identifying a ‘Goldilocks’ zone for optimal plant performance. ​ ​ In four experiments in relatively controlled conditions (PPFD = 215 μmol m−2 s−1, daylength 18hrs). LED lighting increased yield (1.8 folds) and energy use efficiency (2.8 folds) as compared with fluorescent lamps. ​ ​ Adoption of MTRWB (RB = 3) maximised yield (by 2 folds as compared with TTWR 1.5 folds), also increasing leaf chlorophyll and flavonoids concentrations and the uptake of nitrogen, phosphorus, potassium and magnesium. As the red portion of the spectrum increased, photosystem II quantum efficiency decreased but transpiration decreased more rapidly, resulting in increased water use efficiency up to RWB (75 g fW L−1 H2O). The transpiration decrease was accompanied by lower stomatal conductance, which was associated to lower stomatal density, despite an increased stomatal size. Both energy and land surface use efficiency were highest at RWB. We hereby suggest a RWB ratio of R =70%, B=25% with nominal use of W=5% (to view the plant colour and density) for most effective plant cultivation, however further experimentation is required to find the optimal balance and ratio of this LED configuration with respect to density of the overall wavelength. ​ ​ By measuring the LED wavelength in different sections of the tray over the most productive plant growth showing the highest stomatal density, leaf growth and overall weight it was possible to identify the optimal light balance. ​ The LED strip configuration resulted in different plant growth over individual plant species allowing us to record specific growth in that region of the tray.

Close Next Next Widely Used LED Bulkheads in public housing areas LEDs have the longest life span in the lighting industry. The average LED light bulb lasts 6 times longer than the average CFL bulb. Besides, LEDs cost anywhere from 40% to 90% less than fluorescents to run. At the same time, LEDs do not generate excess heat, which can add a substantial amount of money to your heating, ventilation, and air conditioning bill. ​ Since early 2016, we have adopted LED bulkheads as standard luminaires for communal areas of domestic blocks in all new works projects under planning or design. Starting from 2019/20, LED bulkheads have been adopted in communal areas of existing PRH blocks during the breakdown maintenance. In addition, LED Exit Signs and Directional Signs have been adopted in new developments tendered out in or after 2019. ​ ​ Source: https://www.housingauthority.gov.hk/mini-site/greenliving/en/common/energy-efficiency.html Contact us for more information

Close Next Next Green Airport Lighting – Hong Kong International Airport (HKIA) Target to be one of the world’s greenest airports and a top-three environmental performer in Hong Kong, the Hong Kong International Airport (HKIA) has adopted a diverse range of green initiatives in its daily operation and development processes. ​ While the aviation industry only accounts for 2% of the carbon emissions resulted from human activities worldwide, the HKIA community jointly made a pledge of reducing carbon emissions by 25% per workload unit years ago. The energy saving program has been drawn and the project of replacing traditional lightings with 81,000 LED lighting units in the passenger terminals. ​ The program has undergone in August 2011, HKIA has retrofitted 24,500 lighting fixtures with LEDs to save 3.9 million kWh and 2,200 tones of carbon emissions per year. Facilities/locations has completely retrofitted with LEDs include directional signs in Terminal, general line in Baggage Reclaim Hall and T1 Automated People Mover (APM) platforms. ​ The Hong Kong International Airport has retrofit high power metal halide floodlights with LEDs with power consumption greater than 100W. This project achieved at least 40% energy saving while maintaining good performance of the lighting system in terms of illuminance level and uniformity and provide a comfortable environment for the passengers. The deployment of high power LED is a significant milestone in the development of LED as the present domestic market only focuses on small power LED. Contact us for more information
