The lighting on Santosha was all G4 halogen bulbs between 10w and 20w. I ordered 2 batches of 10 LED replacements from a China supplier on ebay with an individual bulb cost of about $7 USD. The 6 SMD are 1.5w and fit in the small round overhead fixtures nicely. The 8 SMD are 1.8w. All are 2700k color temperature which is warm white. Care needs to be taken not to break the leads loose from their printed circuit boards, this happened to several that I was a little rough with but I was able to super glue them back in place with no problem. I used some dielectric grease on the leads to prevent corrosion. I am very pleased with the new lights and the color they produce. They do not get hot and save about 35AH per day in normal use. I have more shots on my web site. santosha.info/html/led_lighting.htmlGene

That is great Gene, exactly what I was looking for , and this time someone (you) took the effort of taking pics and supporting them with an evaluation. This time I am convinced , would you be able to give us the adres or link . Thanks
Edit:
By the way Gene , looking at the pictures of your boat , I noticed you have a fairly huge outboard on the back . Is that only for the dinghy ?

are you saying it was 4 am when you wrote the last post? that was about 8:30 PM here on the left coast of North america. I'm thinking it is about time to go to bed! as it is 9:48pm. With that in mind, how is tomorrow shaping up?

No Marty, my last post was at 5:30 AM ( central european time )
Good night to you all , must be sweet dreams now the health insurance reform past the house.

Yeah it is time for bed and sweet dreams!
Not sure what to say about the health care, right now frankly, a bunch of baloney on the negotiations, voting etc. But in a few yrs, it will all straighten out I hope. Long run, I think it will be a good thing for us, but there will be bumps in the road, needless to say. Probably best to keep this disCUSSion to a minimum, as it does bring out some different temperaments when talking to folks!LOL
about 10:30pm, time for sleep, 5am alarm will roll around sooner than I want it too!

Good evening (night) USA,
yesterday i've ordered a batch (ten) of the 6 SMD bulbs Gene was talking about . Free shipment , 70$ , hardly 50 Euro , so no big deal , if they are any good i might decide to replace every light . Although 10 bulbs will cover a major part of all the lights present in my boat. There are numerous led replacement bulbs on the market , but the reason why Gene's leds convinced me , is the color temperature . 2700° K is the very soft example of led bulbs. I feel the light inside should be warm and cosy instead bright/whitish/Blueish . Most warm leds I encountered where atleast 3000° K and plus.
Once they arrive I will pick up this thread and give you my two cents worth evaluation
Greetings

Good evening/night!
About 10pm here right now, again.........just home from a YC meeting.
I keep thinking the LED bulbs would be good. but I looked at a local chandelier, I recall one being about $18 vs 2 st bulbs at $4 per pair! then again, with one 85 ahr battery...........power goes away somewhat quick, but not that quick....................

I just installed ten of the 6 SMD halogen bulb replacements and am very impressed. They are extremely pleasant because of the warm white light, maybe even warmer than the halogens they replace. Only problem is that they are too bright for "mood lighting" after dinner! Has anyone found a good source for dimmers for these LED's.
Cheers, Andrew

I built a waterproof outdoor LED array (4800 lumen IIRC) and put in an excellent dimmer built from a kit available at the local equivalent of Radio Shack. The key element is that the dimming is not done by reducing or changing the voltage but uses PWM (pulse-width-modulation) that essentially switches the LED lights on and off very quickly, leaving the "off" period to be longer the more you dim the light. This is great for boats in that the energy consumption is reduced and not wasted as it otherwise would. I put more pictures at www.sv-zanshin.com/LED.html

Looking forward to seeing that installed. Cockpit lighting is on my "list".
One note on dimming and LED's in general. Turn your VHF on and listen for electrical noise while dimming. Some LED's have a lot of electrical noise and I would imagine dimmer circuits need good filters too.

Gene - I didn't finish the installation because I needed to make holes / insert grommets into my Bimini and wasn't able to do that alone while the bimini was installed. I did jury rig it a couple of nights and even at the lowest dimmer setting the light is enough to read by, at full power the lights are far too bright and I regret putting two strips in each enclosure instead of just one. The interior LED lights in G4 sockets are somewhat dimmer than the original halogens but I chose the weaker 'soft white' ones intentionally and their light is sufficient for all but reading.
