12 volt RGB (red, green, blue) lighting has a common 12 volt input which in most cases is the black wire. The red, green and blue wires connect to ground for corresponding color channels. RGB lighting is practically universal and is perfect for lighting accent areas. RGB lighting falls short [...]
NMEA 2000 is a standard for networking marine electronic devices, established by the National Marine Electronics Association (NMEA). It is based on the Controller Area Network (CAN) bus system, which is also used in the automotive and industrial control sectors. NMEA 2000 allows for the integration and interoperability of [...]
SHADOW-CASTER® underwater lights for boats do get warm and rely on water immersion to stay cool. However, if your lights come out of the water when running on plane, the small amount of splash they receive is enough to keep them cool. SHADOW-CASTER® underwater lights utilize a thermal protection circuit [...]
A typical group D battery stores approximately 120amp hours of power. 2x SCM-10 underwater lights will draw about 7 amps. This equates to at least 17 hours of continuous use. It is not recommended to deplete marine batteries to less than 20% of their available capacity. [...]
The appropriate number of lights to use is a personal choice and depends on desired brightness and budget. There are no hard and fast rules to apply here. SHADOW-CASTER® underwater LED lights for boats have a very low profile and produce a wide beam pattern. Generally, Shadow-Caster recommends 2 [...]
Shadow-Caster’s full color underwater lights such as the SCR-24-CC or the SCM-10-EXT-CC have become the most popular choice for boaters that don’t want to choose just one color. However, users can choose one of 5 single color options. The condition of the water where the lights will be used [...]
Direct LED Wiring Should you wish your RGB lights to output a fixed, single color this can be achieved by hard wiring individual leads, or a combination of leads, from your RGB light to output up to seven different LED colors. The table below details which wires should be [...]
Shadow-NET® is a proprietary SHADOW-CASTER® technology based on a CAN bus that is integrated into SHADOW-CASTER® lighting products. CAN (Control Area Network) is very robust and has been used extensively in the automotive industry for digital communications. In the marine industry it is the basis for NMEA 2000 networks [...]
SHADOW-CASTER® underwater lights are designed to live under the water. Anyone that owns a boat, especially boats that live full time in saltwater, understand what a harsh environment this is. Combine corrosion with the fact that barnacles quickly grow on anything left in the water, and it is easy to [...]
