Found a new potential source for the LED's. No more breaking light bulb housings.

If we can find these in rgb you will be onto something. Kind of getting sick of the blue until I pull up to my friends dock and everyone goes craZy.
I found them in Red, and also in white.Quote:

RGB would be neat, but would also be 1/3 as bright since instead of having 3 LED's per chip they'd only have one of each color, correct? So you'd be sacrificing brightness for color changing...
True !Quote:

Nice find, and very cheap !
I'm assuming the answer is yes, but does anyone know for sure if these (the lights in the epoxy) will overheat out of the water?
I don't see how they would over heat since they are lights to use in your house.

Same here,
I tested it few hours out of water when I finished it, no problem. And I have to say that they have now 3 years of almost every summer day use, and they are still alive !
I remember those factories on a friends MC X35 died one by one dot every month.
You can go with those SMD cheap Led Montgomery, it's so cheap that you can build 20 units until you hit a commercial underwater led price ;)
I picked up 5 and about to order more, just for the heck of it. I have blue LEDs in random spots throughout the boat to light up the inside at night, but I think I may replace them with these to really light that thing up lolQuote:

I didn't pour resin on it, and they still work :

Check at post #187 to #193
Nice and shiny man ;)
Already tested underwater ?
Do you go with or without castor holder ?
What Led do you use ? Those with or without bulb ?
I haven't had it in the water yet, I couldn't find anywhere in the States or that shipped to the States the deep casters so I used rubber plumbing 2" end caps. Here is the link to where I got the LED's

Has anyone found the led lights in the USA. Want the make a few for my bass boat and don't want to wait a month for them to ship from China.
When I got mine off eBay they were here in a week or two at most.

Trying to get them this week. I pulled my bass boat out last weekend to wash and wax it. Was hoping to get them on before I put it back in.
Let us know and take pics of your new underwater leds ;)
Will these work. Blue 5050 48smdAttachment 16221 thinking of wiring two of them per light and making my own mold.Quote:

That way I can make as many as I want without getting those casters that seem to be an issue getting now. My question is now that I won't have a dark frame around the edge do you think I should darken the edge so I can focus the straight out instead of out the entire block. Any thoughts
Attachment 16229 well after thinking about it I have come up with something for a mold. They are reusable and should work perfectly. The square led lights I picked up fit in the soap mold and give me enough room on the sides for a screw hole. I'm thinking about spraying the sides and back of the light with spray paint or plasti dip so the light get focused straight out.
Hi Cusefan, I'm not sure spraying or adding some black or anything else on the sides will change something. I built tower leds for my boat, you find it here : https://forum.supraboats.com/showthr...-France/page27 I positionned the cap low to prevent leds lightenning the boat dash. Unfortunatly it did. I removed those leds from the tower when I mount the new HLCD speaker box, 2 weeks ago.
Just build it as you planed, and see how it looks. My first prototype is shiny and we clearly see that I used 140° leds.
It will look clean and chic with a rectangular form.
Just, keep in mind that resin is Crystal clear, you will perfectly see the back of the PCB, wires etc.
That doesn't really bother me. Other then me nobody will ever see them out of the water. If the edges come out of the mold super clean then I probably will leave the edges Raw. What do you think about pouring them upside down. What I mean is placing the back of the panel towards the opening in the mold that way the light side will have the natural round over from the mold. Thinking about placing something small on the bottom of the mold to hold the led panel above the bottom of the mold. Was even thinking of using fishing line to suspend the lights up off the bottom
Hi man,
I did the same on a prototype you can see on page 12 :
https://forum.supraboats.com/showthr...ter-Led/page12
Leds were facing the inside of the can, I did suspend them with bended paperclip and a plastic sheet on the can's border (see the scheme).
Fishing line will be invisible, great idea man ;)
Well here goes nothing. Attachment 16244
I spent some time at hobby lobby today and met an nice old lady that was picking up resin also. Turns out she does this on the side and sells pieces all
Over the country. After picking her brain I'm trying a different resin then I used last time. I'm also pouring them differently. I started out by mixing 3/4 of a cup of resin. Poured it into the bottom of the mould. I then waited about 45 minutes till it turned into jello consistency. After that I painted on a thin coat of resin and embedded the led panels into the jello making sure they were centered. After that I poured another layer of resin into the molds. The older lady said to not pour it on top but to pour it down the side so it can spread. This method will minimize the air pockets trapped between layers. After they were poured I grabbed a hair dryer and quickly ran it over each mold to bring any residual air to the top. I'm now waiting for them to dry completely so I can demold them. Cross my fingers and hope they come out as nice as I'm hoping. I'll post pics tomorrow after I pop them out of the mold. All together I have around $65 into 4 lights. My next batch will be even cheaper because the molds are reusable
Sounds great, can't wait to see the final result :D
So here they are. When I removed them out of the mold I found one air bubble in the face. After researching resin polishing I did I light wetsand of the face with 1000 grit. I then added another very thin layer of epoxy over the top of them to make a dome look to the top. I also brushed on a thin coat of epoxy around the edges to seal in the black paint I used on the sides. For my first batch I think they came out pretty nice. I'll post pics of them lit up tomorrow. After I mount them and the silicone dries. Attachment 16245Attachment 16246
Cool man ! How bright are they Vs round ones ?
It's hard to tell because I have 4 on my bass boat and three on my supra but from looking at them they look brighter and the blue light projects further in the water. It's not really a fair comparison though cause the supra has the platform on it and the bass boat doesn't plus the bass boat sits a lot higher in the water but I'm going to build some new ones for the supra this fall. They do seem brighter though. I saw a blue haze after looking at them out of the water and don't remember tre round ones doing that to me.
Can anyone send a link to the cups they ordered for this project? I'm finding the site very hard to manage and not finding what I think I need. Thanks

Hi atlong, the link didn't work anymore for USA ordering, I found it from UK, if it helps :
http://www.componentforce.co.uk/cate...-castor-holder
Try "castor holder" or "castor cups" on Google and see if you have more chance ?
Anyway you can use any similar stuff, or even pour it in a cake mold and get a époxy led without cup, only clear resin.
Hello guys,
Looking to get more Lumen underwater led, I just found this cup holder :
https://www.amazon.com/Magic-Sliders.../dp/B000UVMOBW
It should do the job well, as the one I posted on first page seems hard to find in the USA.
I'm also about to build a new model, using 10w High power blue led :
http://www.satisled.com/10w-high-pow...und_p1393.html
With this kind of aluminum holder, to get heat exchange with water, as I'm afraid it will burn quickly in a plastic holder :
http://www.planete-sfactory.com/pipe...pour-bang.html
It's a bong aluminum base holder :rolleyes:
My lack of English vocabulary doesn't help to find this kind of aluminum holder for other applications. Anyway it will do the job. Outer diameter is a little too big but is still ok for what we are building.
Can also be this kind : http://www.ebay.co.uk/itm/Solid-Bras...-/161986943937
I edited the first post on page 1 with links to Trayson PCB led find and the new caster holder.
oh thats cool
