[PSUBS-MAILIST] K-350 plans

Wed Feb 1 16:59:30 EST 2017

Rick send me your email address off line and I will send you the plans for
 the 5K lumen exterior light I use for my boat.  My email address is
cliffordredus at sbcglobal.net.  I have one of these on the port side of my
boat and in the process of fabricating a second this month for the
starboard side.  Plans will address your questions.
