Solar Light Trap (SMD Version) PCB Size 45x45 mm Protect your crops from all harmful nocturnal insects ! (No Pesticides No Electricity No Maintenance) Solar Light trap is the most effective pest management tool in the hands of the modern, knowledgeable, progressive farmer today. It uses no electricity and no #pesticides or #chemicals, very easy to install (the farmer can do it himself), needs no #maintenance, is fully automatic – switches on by itself when it is dark, switches off after 3-4 hours and is absolutely safe to handle. It is very effective against all kinds of flying nocturnal insects – big or small and specially the harmful pests that are known to be very active during night time. Its Ultra violet light attracts insects from far, but is not useful as a domestic lamp and so is theft proof. How it works: During day time the battery gets charged by Sun light absorbed by the solar panel and converted into electric power by the electronic circuitry and stored in the battery. During night time, this stored energy will be used by the Light and Fan fitted in the Trap. The Light and Fan are auto switched on as it gets dark and would work for four to five hours. #harmful nocturnal or night flying insects which are most active during this time are attracted by the ultraviolet light emitted by the #LED's, enter the funnel area and sucked into the bag by the rotating suction fan or fall into the tub with emulsified water. Once they are trapped in the bag or water tub, they can not escape anywhere and ultimately die out of exhaustion and lack of food. TECHNICALSPECIFICATIONS Light : UV LED of 390 - 400 nm Solar Panel : 4 to 12Volts / 6 to 10 #watts System Operating Voltage : 4 to12Volts DC Battery : 4 to 12Volts / 3 to 7 Ampere Hours Effective Duration : 3 to 5 Hours https://www.instagram.com/p/CNfJOiogYDh/?igshid=lighmc14wvnq
