Title: Waterproof (IP67) LED's question
Post by: davejay on May 19, 2021, 10:04:07 pm
Hi all,
With the build of my RoMarin Najade being started imminently and that it is representative of the mid 90's Sunseeker 48 Manhattan boat, I've seen some real craft and models with underwater lights (two on each side toward the stern and two on the transom. I would really like to have this effect especially during late evening sailing in the future. I intend to also have lighting under the flybridge as well as the 'standard' nav lights and a spotlight.
If anyone has any suggestions as to where I can obtain these LED's I would be really appreciative. Ideally they need to be bright white with chrome bezels and about 10mm across the bezels. Also some advice on wiring them in. I'd imagine teh voltage would be between 6 and 12v.....9v being ideal as I could you a PP3 type pack!


All the best,


Dave

Component Shop guide to LEDS  would be a good place to start .

All LEDs are waterproof.  Their connections are not. 
Ordinary LEDs just mount into the right size and shape hole, with the wiring inside the hull, or, in regular terms, behind the panel. 
Various styles and sizes of mounting bezel are available, mostly either black or chrome.  The trick is making sure that assembling them into the hull gives a watertight result.
A google for "Chrome LED bezel" give a selection of choices.

Not mentioned is to ensure that you have the correct resistors installed for your LEDs. They will vary according to Color( of the LED ) and te wiring, series or Parallel, as well as the number of LEDs in each circuit. There are numerous calculators available on-line, for both series and parallel installations.
