I decided that it would be a fun idea to put some cheapy LED worklights (which are IP67 rated) and weld them to the trim tabs on the boat. the ones I used were from eBay

Well I bought 4 so that if they wernt quite ip68 then for that price i had some spares.

Finally went down to Dartmouth and tried them for the first time, and wow! I never expected them to be that bright and effective, the pics don't to it justice!

Next time (when I remember the fuel can for the dingy...) ill get some shots from further away!

I often wondered........ I guess the next question is, how long will they last??????

But bravo for trying.

Will be interesting to find out.

Just out of interest, how does the quality look when you see them in the flesh, so to speak? If the Op thinks it's good I might be tempted to fit a few to my tender, also in the Dart.

Interesting. I wonder if the manufacturer had in mind them being submerged in salt water for 365 days a year!

Precisely, they are aluminium bodied, so unless you attach anodes to them they will corrode away to nothing PDQ. Have a look at the materials used by a proper manufacturer of underwater lights www.lumishore.com and you will see that they use marine grade aluminium bronze alloy housings.

IP 67 rating states that the test need only satisfy submersion for 30 minutes at 1m. I would guess/bet that these units were not designed to be continually submerged and the seals will eventually let water in within months or even weeks.
 
Yes, alas, seawater and seawater critters will work thru the seals in a fairly short period. Nice bit of diy-ing though!
 
Well if they last a season, then great, otherwise its hardly a big job to change or take off!

Yeah i know they are alu + stainless bracket and will corrode like no tomorrow.. and one is filling up a tiny bit... but its only a laugh at the end of the day! it will help that my boat lives on its trailer in the boatyard when im not there so its not total submersion. Plus i went around the seals with some silicone to give it a better chance. Maybe the spare two ill fill up with clear resin, as no chance of water ingression would take place there, even if the alu completely corroded it would still work.

My other plan is that i have launched it at dusk straight after work with a 4 hour drive inbetween last season, these could help the process to see the back end when reversing.


Longjohnsilver - pop me a shout when your next down if you like and Ill show them :) to be fair their not too bad, for a tenner a pop... and blimin bright.....!


Have to remember its only a bit of a laugh, and maybe to have a tiny bit of smugness pulling up to a super yacht with 1000's spent on theirs...... ;)
 
Will do. I'm thinking maybe have them on a sliding bracket so I only submerge them when I want to turn them on.

Certainly no competition for Lumishores that I already have on Eos.....
 
Hmm maybe they will last then....? Who knows!

Yeah not a bad idea as long as they dont fall off at speed!! ;) nooo i know its no competition for the big guys, but i doubt their £10 a go :)


I was next door to these guys at METS show Amsterdam - http://www.bgbsils.com/ certainly had a lot of interest as no drilling was needed through the hull-- it uses inductive wireless power. tried to get a sample.....fail.. :D
