Retevis RT97 GMRS Mobile Radio Relay Communication Set, Full Duplex Radio Base Station(1 Pack) and GMRS Handheld Walkie Talkies(2 Pack),Designed for RV Camping,Emergency Rescue
... not only be used in the car as a substitute for the vehicle transceiver.
but also can be fixed on the roof or on the mountain to play the role of relaying signals.
you can directly select different relay channels.
only one antenna is needed to achieve signal transfer.
which is very easy to install and set up.
but you need to pay attention to the power loss caused by the duplexer.
RB27 handheld GMRS radio has 30 GMRS channels and 11 weather channels.
it can further expand the use of two way radio.
The handheld radio supports type-c direct charging and charging base.
you can directly use the usb connector to charge your walkie talkie.
which is very convenient and simple to use.
The 1500mAh li-ion battery can be used for 10-12 hours of continuous use.
with flashlight function and SOS alarm function.
Choose suitable handheld radios and base stations for you to achieve true long range communication.

2 Pack 1000w LED Grow Lights for Indoor Plants Full Spectrum, Plant Growing Lamps with Veg & Bloom & Veg-bloom 3 Modes, Daisy Chain and Temperature Hygrometer for Indoor Grow Tent Plant Veg and Flower
...at labile shortcomings of LED reflectors, if a short circuit occurs, the reflector can easily melt and catch fire, the upgraded aluminum heat sink is applied to improve the heat dissipation efficiency, slow down the light decay, and be safe, energy saving and efficient.
Full Spectrum LED Indoor Grow Light: red light wavelength is 620-625NM, blue light wavelength is 450-455NM, white light lumen is 6000-6500K, infrared light wavelength is 730-740NM, purple light wavelength is 395-400NM, orange light wavelength is 600-610NM, from seeds to flowers, full spectrum LED grow lights are suitable for all stages of plant growth, and help the growth of the whole life cycle of plants.
Extends the Lifespan: this LED grow lights for indoor plants full spectrum have a longer lifespan than most LED lights are rated for, in contrast to many other grow lights that tend to last around 20, 000 hours before needing to be replaced, ours features good technology that extends the lifespan to no less than 30, 000 hours.
This Visible Spectrophotometer adopts a microprogramming technology. It can be used in a material determination, a quantitative analysis in a visible spectrum field. This equipment is a multipurpose analyzer which is necessary for all general labs. It applies to the medical health, clinical examination, biochemistry, petrochemical engineering, environmental protection, quality control’s department and teaching lab of universities and colleges etc..
Fundamental principles: The spectrophotometer analytical method is based on the different materials’ molecular structure’s selective absorption of electromagnetic radiation..
The available electromagnetic radiation’s spectral region is normally between 330nm-800nm..
Main Technical standard: Wavelength Range: 340nm~1000nm.
