FAQ

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

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 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.

2.Is there an attachment that is suitable for a variety of installation methods?

Yes,there is the installing adapter FlangeBase as follows. In order to better heat insulation and waterproof, we recommend to use it.? ? ? ?
