I just had to post a follow-up. The fragile Aqua Signal Series 32 mounting requires additional effort for a marine
application, though I'm sure it would be fine for, say, a tabletop science-fair project
. One of my two new sidelights (purchased from Defender) came with the little expanding plastic broken... making an already-marginal piece of hardware
I hope the optics, efficiency, and RFI were not the responsibility of the same department that cobbled together the plastic. I trust the Luxeon, but I have no idea what is being used as a constant-current regulator
, something that is hard to do quietly.
Anyway, since I needed a bicolor on a vertical mounting plate to replace the old milky incandescent model, I made an aluminum
block to do the job. There is a large hole bored through the longitudinal axis, providing a wire channel, and mounting holes 50mm apart take care of sticking the lights to the block. The front one is 6.5mm to pass their wire exit, and the back one is drilled and tapped for 8-32 to allow a slightly turned-down button-head cap screw to apply clamping pressure. Two 1/4-20 threaded holes in the back accept cap screws through the stainless plate welded to the bow pulpit (all with anti-sieze, as well as a rubber gasket).
I'll add a little bead of 4200 or Sikaflex around the front... something about one screw just doesn't inspire confidence.
Oh, that hex-textured surface is an applique of 3M retroreflective material, covering the hole and adding some potential utility in spotting the boat from windward in an anchorage.
Technically, there is no reason why the hole needed to go all the way through, but it really helped with deburring.
below includes the broken piece that came in the Aqua Signal package. Sounds like SailFastTri had the same experience. Caveat emptor
; if I was starting fresh, knowing what I know now, I'd just build my own or spring for those sexy Lopolights.
