DWS503TOP 4NM navigation Solar LED Underwater Marine Light can meet those warning applications that demand more high specifications and its visibility is up to 4 nautical miles. It has the characteristics of solar self-contained, high reliability, easy-operation, and long autonomy.It is generally used for Marine Marking,Obstruction Warning,Barricade and safety Warning etc..

This light complies with requirements of IALA , and can provide 16 IALA flash patterns for every colors : white , red , green and yellow.
It can be installed in minutes.The flashing modes and intensity can be easily selected onsite by the user.

 By now, there are 120,000 sets of Double Wise solar marine lights or lighting lamps operating in more than 80 countries all over the world. Eight Chinese patents and over 20 kinds of solar products are a reward for our efforts.

 1. What is the difference of IP67 and IP68?
For solar lights, IP67 is the same as IP68.There are three reasons as follows:
• IP means Ingress Protection. The international safety standard for IP is IEC60529.IP codes have the format IP××,where the ×× represent numerals from the coding scheme(see Table 1 and Table 2);
                               Numeral                     Characterization of Ingress Limit
                                  0 or X                                       Not evaluated
                                      1                                   ≥50.0 mm diameter object
                                      2                                   ≥12.5 mm diameter object
                                      3                                   ≥2.5 mm diameter object
                                      4                                   ≥1.0 mm diameter object
                                      5                                            Dust-protected
                                      6                                                 Dust-tight
Table I. The first numeral in an IP code indicates the degree of protection from solid foreign objects.
                             Numeral                         Characterization of Ingress Limit
                                0 or X                                                Not evaluated
                                    1                                            Dripping water: vertical
                                    2                                            Dripping water:15°tilt
                                    3                                                    Spraying water
                                    4                                                    Splashing water
                                    5                                                   Jetting water
                                    6                                            Powerful jetting water
                                    7                                            Temporary immersion
                                    8                                            Continuous immersion
Table II. The second numeral in an IP code indicates the degree of protection from moisture.
• In all practical applications, it is impossible for a solar light to immerse under water for long time because it couldn’t be charged in such case. So IP68 for solar lights is nonsense.
• No solar light can pass through the IP68 testing for sure, because it can"t be charged for a long time under the water. The IP68 expression in a solar light only be speculation gimmicks and attempts to mislead users.
