CMH lamps perform very well in the growth stage of plants during planting. UPDAYDAY developed CMH40K LEDs based on the spectrum of CMH lamps.
CMH40K LEDs are the main spectrum of VEG mode. HPS lamps have always been able to obtain high yields for plant lighting. UPDAYDAY studied the spectrum of HPS lamps and developed HPS18K LEDs with a spectral similarity of 98%. Why can HPS lamps achieve high plant yields? The HPS lamp has a very high proportion of yellow light and red light.
The wavelength of yellow light is 580NM, and the wavelength of red light is 660NM. The higher the wavelength, the greater the energy. Under the irradiation of high-energy and high-wavelength lights, the larger and heavier the buds. Utilizes wide distribution LEDs to disperse colors uniformly over the coverage area.
Full Sunlight Spectrum , Brightness Adjustable, Sync Function, Built-in Timer, Sunrise and sunset feature. Sunshine mode is to imitate the process of slowly becoming brighter in the morning and imitating the sun from bright to off in the evening. Create environment close to natural lighting outdoors for plants , increase the growth rate and yield of plants.
390NM :Increases resin production improves taste and smell. IR 470Nm :Increases plant biomass improves efficiency of overall spectrum. Multi-machine synchronization:connection dimming, light model, timer ues commercial growers. Timing function: Can set the light on time from 1-23 hours, keep the electricity it will always cycle. Full spectrum including energy in Far Red to enhance plant development and spectrum efficiency.
Ability to ease plant transition from veg to flower stages. Create environment close to natural lighting for plants. Only when more than 2 UD grow lights are connected through the network cable, can they be operated synchronously. When the two growth lights are connected through the network cable, press the yellow SYNC button, at this time, the yellow LED of the host machine flashes and the yellow LED of the auxiliary machine lights up, the timing setting, light mode switching, dimming and other operation of the host machine will be synchronized and consistent with the auxiliary machine, for the 3 minutes after completion of the operation, the synchronization lock is realized, the operation to be synchronized again needs to re-press the yellow SYNC button.
The maximum number of synchronization is the 30 sets.
