Waterproof DUO for our flexible led “PRO” series
Luz Negra’s waterproof DUO is the only water-tight system with
IP67 which maintains a width of 10mm and its original flexibility
Conventional water-tight systems are composed of one layer of protection and on many occasions humidity can penetrate via capillarisation
between the IPC and the silicone layer, hence provoking a short circuit and disabling the led.
The double layer of the waterproof DUO system (designed by Luz Negra) guarantees an optimum water-tightness for all installations, both indoor
and outdoor.
There are also other systems which involve completely covering the led strip with glue or silicone at 360°, but these systems increase the width
of the IPC from 10 to 12mm (preventing you from inserting in standard led profiles), making them stiffer and decreasing their flexibility.
Our flexible led strips, Waterproof DUO system, designed by Luz Negra,
offer a water-tightness of IP67 yet without having to increase the width
of the flexible strip (which is what usually happens with other IP67 strips
on the market).
Thanks to this, we can install them in most of the led profiles on the
market, whereas the strips with conventional covers increase the width
of the strip by 2mm therefore preventing its use in many models of led
profiles.
The double cover offered in the Waterproof DUO system means that the light projected by the led collides with two layers (the first one, the silicone
and the second, the plastic casing).
This way we achieve greater refraction meaning greater expansion of the light spot, therefore giving out a more homogeneous, diffused light.
