OK, help now, please.

My spreader lights ar here:

The forward deck mast light is here

Stern light here

Red Green Nav lights by Hella here (I have seen these, they look like a glass tube with two conical metal extremities).

My interior lights on the ones outside the liner ans embeded say use G4 10 W bulbs (whatever that means)

I think the masthead light )we call it presence light, only used when anchored) is from Hella.

That is it...can you please recommend bulbs for these? Thanks

Looks like your forward mast light and nav lights use a festoon bulb (glass tube with metal ends). The stern light uses a bayonet base, 2 conductor bulb. #1142 I think. The interior lights are the same type as shown in Mainesail's post, and I have no clue on the spreader lights.

I know Superbright makes festoon bulbs, 1142, and G4 replacements.

BTW - In your picture of the lights, one seems to be missing. The list is of six, but only five shown.
Actually there are five listed and five shown:

#1 Sensibulb
#2 Marinebeam G4/MR-11-10
#3 Marinebeam G4/MR-11-6
#4 SuperBrite LED MR-11 WHP6
#5 Doctor LED MR-11



When I get home I can measure the width of the bulbs PC board. If you take the Superbrite & Marinebeam bulbs/PC board out of the MR-11 glass fixture that is actual the width of the non MR-11 horizontal bulbs..

I'm not sure that if by "bulbs" you mean "emitters," but just in case: SSC LEDs/emitters aren't necessarily inferior. Like any other LED emitter: They need to be driven and heat-sinked properly. Over-drive and/or under-heat-sink them and they'll die.

LEDs are semi-conductors. Heat is a semi-conductor's enemy. To get LEDs to emit a bright light they must unfortunately be driven to the point that they generate self-destructive heat. The only way to save them is for there to be adequate heat-sinking to draw the heat away. You can buy relatively inexpensive LED flashlights these days that way out-perform a "traditional" flashlight--even a high-end one from such as MagLight, but you can not obtain a LED replacement bulb for "old tech" flashlights that will make them perform as well, because there's no way to design a drop-in replacement bulb with the heat-sinking necessary top allow you to drive the emitter hard enough to make it perform well.

This should tell you something about the likely longevity of (most?) replacement navigation "bulbs."

OK I believe you all missed the pallets full of ammonium nitrate. I hope the FBI doesn't see this photo. I wonder if there is a Ryder truck parked outside the garage door!

That´s why I need to get there, see the fixture, bring the bulbs and buy accordingly.

I will search for what I know I have, or think I have, and post here so some of you can help me and in December when I fo to the US I can buy them, ok please?

I too am converting to exterior and interior LEDs not just for power draw (although this is important), but for heat issues. I have very nice 10 W Halogen reading lamps over the aft cabin bed, but they get very warm indeed. As I am moving the bed aft and athwartships, I will likely just run off an existing bulkhead "area" light fixture of the "brass ring" type using an old 12VDC "auto" light and power two reading lamp LEDs from there.

This is one of the generally unheralded advantages of LED fixtures: they draw so little that you can easily "extend" existing wiring circuits with smaller gauge wires, which is both cheaper and easier to secure and to properly run through conduit.

Thanks to Maine/Hal once again for being a better Practical Sailor than Practical Sailor.

The interior lights are G4 Halogens, so they're not a problem.

The Spreader lights are a sealed bulb unit, so you can't do much about them.

The others may or may not be able to use replacement bulbs like the ones from DR. LED.

Personally, I'd swap the fixtures out with Aquasignal Series 25 or 40 ones, depending on the size of the boat, and use the DR. LED bulbs made for them. It's one of the least expensive ways to get all LED navigation lighting.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Spreader Lights from Marinebeam.com

We will have your spreader lights in 2 weeks. Look for the announcement on the marinebeam website. It is a sealed beam unit with 120 LEDs and is plug-n-play with most spreader lights.

We will also have a replacement spreader light with the same form factor, but >9W and >600 Lumens. In final testing now. I can't post pic here because of silly posting restrictions, but can send a pic to those interested.

I can also help with the tube lights (must be a Jeanneau or Bene?)

For the rest of your bulbs, see the marinebeam website.

For a white paper/idiots guide to everything LEDs, download our pdf.

Cheers,


Jeff

Hey GUI-

He called your boat a Bendytoy... or Jeanneau, which is much the same thing...they're both French...
