How to connect the device? What color of cable is minus? What color is high/low power? A short manual shipped together with the product would be perfect, but an explanation in text or picture on the aliexpress page would be good enough.
This is my 2nd time purchase.But this time i cheated.1st odr was 100m range and 15wt was accurate. But in 2nd buy lights are very poor performance 15wt like 7 to 8wt. and spread any where.In seller side specification and in real too different.If packing box remove you cannot judge. I m totally unsatisfied.
This is the bad experience of my purchase. mention 15w is just like 7w.2250lm not mention any where.If u remove cover packet from light u can not define 15w. clamp very poor.clamp bolt on light may thread damage if u tight. copper wire very thin.200m range totally false just 20m.led light life mention by co 50000hr but God know. Light angle not perfect.
