Aqua Signal series 25

[Ian_Edwards]

The Festoon bulb on my steaming light has blown. I've looked at the Aqua signal website and it say the replacement part (90200) is 1 and 7/8 inch long, or about 48mm.
When I search for a replacement bulb I can't find a 48mm 10watt festoon bulb. What I do find is a 42mm festoon with dimpled ends advertised as been a suitable replacement for the Aqua Signal.
The Aqua Signal unit is a combined deck light and steaming light part number 25400.
42mm is obviously 6mm short of the 48mm in the catalog.

Does anyone know if the 42mm festoon bulb will fit?

I don't want to get half way up the mast only to find that the bulb doesn't fit.

I used to have this light, changed it out for a larger one though as it was undersize for the boat.
Looking at the Aquasignal site, it indicates the festoon bulb is 41mm in length.

You could replace it with a LED type, also the downlight at the same time.

Thanks Nigel1, the site I was looking at:

http://www.aquasignal.info/us/files/content/series_bulbs.pdf?id=204

provides different information, but the page you turned up looks more like the unit I have.

Two types of series 25 lamps I think you will find

Mine were the original types. Now called "Classic" IIRC.

They take ordinary pointed end bulbs not the dimpled end type. You need to know what type your's takes!

The tangs between which the bulb fits can be bent a bit to take bulbs that are slightly the wrong length.

Beware of cheap non genuine replacements. There can be a big variation in brightness even though correctly rated. Wonky filaments can affect the visible arc too but perhaps more important in a side light or bicolour.

Not wishing to hijack this thread, I have had nothing but trouble with the Aquasignal 25 'downlight' part. For some strange reason it seems completely open to the elements from the underside and the bulb contacts seriously corrode. After cleaning I am lucky to get more than a few weeks before needing to clean them again. I did ask Aquasignal and they said that due to the heat of the halogen bulb they could not put a sealed cover over the downlight part.

From the catalog it looks like you have to go to a series 41 to get an IP67 downlight combined with steaming light.

Do you know if the two fittings (S25 and S41) mount in the same points? The Aquasignal web site has no mounting instructions/dimensions for viewing/download.

Thanks.

Yes it is piss poor. The boat I crewed had one. The deck light seldom worked.

I looked at it once. IIRC it has a halogen bulb with a BA9 base and one of the connections is via a spring which rusts.

I'd think that the mounting for the series 41 is totally different. I may have fitting instructions for series 41 lamps somewhere. That's not all that good either IIRC. One page for all types in all known languages .

Yes,the deck light bulb is open to the elements, but mine currently works.

VicS thanks for the info' about the rusting spring, I'll be prepared for that when I replace the Halogen with the LED I've just ordered from Boat Lamps (along with an LED replacement for the Festoon). I'll coat the contacts with some appropriate water resistant grease and hope it last the season.

I intend to take the mast down this coming Autumn for the winter and I'll replace the combined steaming light and deck light with something better engineered and correctly specified for the boat. The type 25 is rated for up to 12m and my new (to me) toy is 14m so should really have the next size up. I don't understand why Northshore/Selden fitted an under rated steaming light when the boat was built.

Correct re halogen/bayonet. It used to be just the two prongs of a halogen bulb on earlier versions but those tended to fall out!

I think the Series 41 bulb is a sealed 50W halogen but I am not sure of the fitting.

In a perfect world it would be nice to just replace the series 25 with the 41 using the same mounting points and hoping the cable does not need to be longer!

The cable entries for the AquaSignal series 25 and series 41 combo lights are both at the top of the respective fixtures. The cable length needed from the cable entry to termination looks similar so replacing a series 25 with a series 41 should not be too much of a problem, cable length wise. The series 41 is a much larger beast. I took a photograph of the interiors of both units side by side which illustrates the difference in dimensions.

We tend to prefer replacing the 20W halogen deck light lamp of the series 25 with a BA9s LED mini spot light lamp. We had to design a new lamp to give adequate light output. We use a Cree high power (3W) LED lamp built into a heat sink with a lens which lights a deck nicely and avoids the heat and heavy current requirements of a 20W halogen lamp.

Picking up a few other points raised in this thread:

Corrosion of the unprotected deck light lamp holder of the series 25 combo light is a common problem. Poor contact and particularly surface corrosion of the lamp base solder contact combine and result in overheating and distortion of the BA9s lamp holder. I would advise any boat owners that use the series 25 combo unit to consider replacing their high current halogen lamp with a low current LED version. Before fitting the replacement lamp the base contact and the internal surface of the lamp holder should be lightly cleaned with fine wet n dry paper. Wipe it clean and use a generous dollop of Contralube 770 in the lamp holder. A pea size amount would be fine, spread more onto the lamp base and insert the new lamp. The Contralube will not only halt existing corrosion but will also protect the exposed lamp from the weather.

Technology has marched on and replacement LED lamps are now available for the big 50W deck light lamp used in the Series 41 Combo light. We use a waterproof 10W LED lamp sealed to IP67 standard which is robust, reliable and has a very much longer working life than the lamp it replaces. Many incandescent lamps fail simple because of the day to day bumps and knocks common place on our boats. Exchanging lamps is a simple swap out for the existing PAR 36 glass lamp. Apologies for the commercial and would of course add that these lamps may be available from other suppliers, although I don't know any who stock them....!
