LED Questions
« on: April 12, 2017, 08:29:15 pm »

Hi,

I am looking to install underwater lights onto one of my boats to illuminate the running gear at night.

What I really want is a nice even glow across the transom of the model rather than the 'needles of light' that LED's sometimes offer.

Any ideas how I could get an even glow and ways in which to seal the water out? I have a few ideas but any other suggestions / ideas are greatly appreciated.

Thanks in advance!

You could experiment with these. Maybe somebody else on Mayhem has tried them. We used them on our tow as deck lights and they gave a more defused light than individual LEDs

Sanding the l e d will help a lot to  diffuse the light,  and the water will diffuse the light as well. If you set the l e ds into the hull with epoxy they will be waterproof. Years ago I remember seeing a model submersible where the builder had just drilled holes and epoxyed them in, it was very effective.

Try looking at this page. It shows the piece of clear acrylic I used on Nautilus to help diffuse the harsh spotlight effect, normal with LEDs. Something like this could be epoxied into hull sections.

I asked the same question regarding fitting underwater lights on my Moonraker and was recommended 5mm. flat head LEDs.  Hope this helps.

You could be right there. We dressed up a Tamiya Coca Cola Christmas Truck with these. Only really good for low light or darkness as mentioned. Mind you, I doubt any LED would have much luck against natural sunlight anyway, more of an evening or night effect anyway..

Hi again,


Thanks for the advice, much appreciated - I will have a look at the options and will post the results on another thread once I have finally finished the boat!


Thanks and happy Easter!
