Product Details : Key features: 1. We use super-capacitor as energy-storing parts, which can be used more than 100, 000 cycles repeatedly and can meet environmental needs.2. Two reinforced veins are designed on the top edges of it to not only strengthen compression resistance but also protect the solar panel against compression from traffic loads. 3. 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. Upper surface with abrasion- resistance treatment, to protect from being scraped and ensure photo-electricity transform efficiency of solar panel.5. Two screw holes are designed on both sides so as to be fixed firmly in road with high requirement of stability.6. Taiwan Intelligent control IC and USA original exactitude potentiometer together ensure long life in use and big enough capability.7. Three grooves on top can be an access for rain water, sand and small stone so as to prevent the solar panel from abrasionTech specification: ItemDescriptionSolar cell TypeMono crystallineVoltage3VCurrent65MAcapacitorTypesuper-capacitor 50F 100F 150FVoltage2.4VCircle life 100000 circleover 10 yearWork temperature-40+80LEDFlash wayblink or steadyFlash frequencyAs you requiresizeΦ10 mmnumber2×2PCSColorWhite, yellow, red, blue, greenLuminous intensity2000mcdControl circuitsICOperating time (single-side)150F, charged in the sun for 8 hours available for 36 hours blinking lighting and 8 hours constant lighting. 2100F, charged in the sun for 8 hours available for 48 hours blinking lighting and 12 hours constant lighting.3150F, charged in the sun for 8 hours available for 72 hours blinking lighting and 18 hours constant lighting.Compression resistanceover 10 TonStarting intensity500 LUXApplication situationEdge lineLife in useOver 5 yearWeight:550g (single-sided) and 520g (double-sided)Material of body shell:aluminum alloyMaterial of solar panel shell:PCMaterial of LED shell:PCMaterial of body insideEpoxy glueWater proofIP68View distance:over 500m
