Hunter 376 Chesapeake Bay
I went up the mast today to replace the bulb that shines downward onto the deck of my '97 Hunter 376, from the steaming light fixture. Turned out the bulb was broken, and I can't identify the size of the bulb, except that my manual says it's a Z-spar bulb. :confused: Does anyone have more info on what bulb I need to replace it? Where I can order or find one? It is not the same size as any of the other bulbs on my boat, which are all specified in the manual. Thanks!

Deck Light H376

The one on my '96 H376 is a horrible open fixture with no glass to keep the weather out. It was always failing.
However I found that the small size 12 volt 20 watt sealed beam low voltage dichroic downlighter lamp fitted it just perfectly - as used in domestic applications at home.
I think I used the MR16 as a replacement 2" diameter type GU5.3 or it may have been the smaller 35mm diameter one with a glass front cover type GU4. Sorry I cannot remember. The point being that it fitted the existing hole exactly. Also being sealed beam there was nowhere the salt spray could get in. Having only recently been up the mast you will probably remember whether the hole is 1 3/8" or 2" and you may well already have a spare one at home.

It was necessary to make connections to the bulb's pins which I did by removing two connectors from a 'chocolate strip' connector and screwing them directly onto the bulb's pins and separating them with a small piece of PTFE tape. The beam down on deck is marvellous.
All this was 8 years ago and still going strong.
