Shell adopts one-off molding, greatly improving its Compression resistance. Solar panel, electronics and optics are fitted inside waterproof, dustproof and unbreakable up to International Standard IP68. 4. Two screw holes are designed on both sides so as to be fitted firmly in road section with high requirement of stability.Technical features: Solar stud: ItemDescriptionSolar cell TypeMono crystallineVoltage4VCurrent80MABatteryTypeHeat-resistance Ni-MH Voltage2.4VCapacity800Mah(steady)Circle life 1000 circleover 3 yearWork temperature-20oC----+70 oCLEDfrequency1Hz or at customer request.sizeΦ5mmnumber2×3PCSColorWhite, yellow, red, blue, greenLuminous intensity2000mcdControl circuitsICOperating time (single-side).charged in the sun for 8 hours available for 24 hours blinking lightingCompression resistanceover 10 TonStarting intensity500 LUXApplication situationEdge lineLife in use3 yearWeight:292gMaterial of body shell:PCMaterial of body insideEpoxy glueWater proofIP68View distance:over 500m Control system: ItemDescriptionsolar panel 17V/5wbatterycolloid battery specially for solar use, 12v/2.2AHOperating time (single-side):8 hours charge can offer energy for 36 hours flash frequency1Hz/2Hz or at customer request.Operate condition:-20+70Starting intensity500LuxSize:185X100X260mm,Control distance:Radius 100 meter.
