After several years in the industry, with some occurrence of cold solder joints, on March 10, 2018 I began shipping my LED spars/guards with my third product improvement (Version 3). Although indiscernible from the products' exterior, I’ve designed a way to further reduce the possibility of cold solder joints or solder-breaks developing throughout my products' lifetime.
In lieu my original designs utilizing a 15 LED one-piece Printed Circuit Board (PCB), I’ve redesigned the LED array to consist of 15 separate daisy-chained PCBs, each PCB with an independent LED/resistor combination. Each PCB is then installed in shock absorbing potting material, isolated from the neighboring PCB, greatly improving the LEDs' ability to absorb impacts. Also, this newest design features brighter and whiter LEDs.
