Building your own underwater Led

Hi and thanks big517 for your interrest.
I will put many reserves on the link you give. These kind of led bulb does not provide brightness. First it's MR11, smaller than MR16 bulbs. Then they are fitted with standard LED, and that's a problem. It's not powerfull at all. I think it will produce equivalent of 15W incandescent light, it will probably be not more than 1 or 2w real consumption.

You really should go for at least 5050SMD or CREE high power model LED on a MR16 bulb.

No issue with wires, we talk about really low wattage, so no problem with any kind.

@sdc77 you are under the impression that the bulb is a 15w equivalent, i really hope it's not. I will have my hands on them today and test immediately.
I also considered the 10w single chip epistar and Cree chips however I couldn't find a US retailer so delivery would have been a month. Then I stumbled onto these mr11s. I will be very upset if I find they are advertised wrong.

Salut Sdc77 !! Cette année j'ai finalement eu un peu de temps pour installer mes lumières !!
Hey guys , this year i finally had time to install my 2 RGB led spot light ! It's pretty cool and it glow way more than my best expectation, especially for the price !(+/-50$)
Unfortunately I didn't have my iphone or a camera when test them.. Next weekend i will take some shot for you guys !! I didn't try them at night while cruising but i will and i hope it will glow enough the wave to be able to ride in the dark ! The only thing is it's a bit tricky with the remote to change colors or to put strobe/flash mode. I have to put the first end of the remote (IR) in the water to change color but it work and in my lake the light blue color is the best and way better than the white/green and other.

This is what i bought :

Salut Olivier !
Pas mal du tout ton système, puis de les avoir accroché sur les équerres de la planche de bain c'est pas con ;) Hâte de voir ce que ça donne de nuit sous l'eau, 10W c'est pas rien !

Nice system, cant' wait to see it running by night underwater, 10w is something

Cheers

Did a little bit of night surfing last night. It was a blast. This video does a great job of showcasing my transom LED's. They look so awesome while surfing. Thanks again for the DIY input!!!

You can also see my surf system in action.

I even wore my Ronix LED vest!

Cool vids man ! Your boat really rocks with the decals, hifi, bleu leds everywhere ...

So how did those big lights work. I'm curious.

Does anyone know where you can get these caster cups now, the link in this thread only sells them in bulk of 500 or more now.

I started with a foot plastic hider sheet, found in my construction shop. It's 60mm diameter, exist in black or silver :

Here is a link to get it in USA : http://www.componentforce.com/catego...-castor-holder

Then bought 2 home leds, 12v DC, blue, with 24x SMD 5050 leds :

You can go with a 30x SMD bulb : http://www.dx.com/p/mr16-470nm-5-5w-...5#.U4ROOlKKCUk

Broke it to keep the PCB :

Then glue the pcb (with 1 meter wire welded) to the plastic sheet with spacers (it can be a water bottle or soda cap), to escape the stuff behind the PCB, and pour casting epoxy resin in it. You can use this resin : http://www.michaels.com/easy-cast-cl...=epoxy&start=8. 24 hours after, it's crystal clear, solid and perfectly sealed :

Since we can't get the "Black Caps" here in the States unless you order in bulk I found this substitute over the weekend... I will post pics soon but here is the link
