LED Lamp Conversion. 1. In the spring (2009) I replaced both masthead lights with LED units on my Hunter 306. I was hoping my recurring anchor light problem wasn’t a contact or corrosion issue, of course...but, anyway, for the LED units, I bought 2 “Dr. LED Polar Star 40” units – replacement for the Aqua Signal series 40. Note that these say they are 2 nm rated, and current draw is 0.9 amps or less. Meets CE standard, and should satisfy USCG requirements, I think. Both are their replacement for the 25 watt AND 10 watt bulbs. (Prices BTW, for comparison, at WM standard incandescent 10 watt and 12 watt bulbs were $19 and $20, and the Polar Star 40 LED units were $50…though with a little searching you might find them for about $44 elsewhere (Svendsen’s offers them a bit less).) Oh, and the festoon bulbs for front (bicolor) and aft white Hella Series 3562 nav lights have already been changed to Mastlight.com 44mm festoon-type LED units. (You can use the bright white unit in the aft white lens, but they recommend you use the “warm white” unit for the bicolor lens.) Costs for these units were about $20 each, as opposed to the $2-3 for the standard festoons, but current drops very significantly – to about 0.2 amps. Oh, and life is estimated to be 50K+ hours for these LEDs, though I still have to worry about contact corrosion. We’ll see… Anyway, writing this at the end of the 2009 sailing season….all LED lights for Navigation worked fine all summer. (So let’s assume I had no corrosion or contact issues with the masthead unit initially.) I hope I don't run into the 200 hour failure issue reported above for Dr. LEDs.
[FONT="]2. I also recently changed all the cabin lights to LEDs. FYI, for the G4 halogens (six in the main salon, and one in the head….way aft) that came with the boat, I changed to flat LED units (from Superbrightleds.com), and the 2 spotlights with G4s in each of the berths I also changed to long round LED units. I also had three “wedge base” light units, one at the entrance to the aft cabin, another in the head, above the sink, and a third in the middle of the aft berth, and I changed these to LEDs also. (The 7 flat LED units – warm white – with composed of 6 LEDs. Each G4 unit cost $11.95 each (X 7). I would say these are only slightly less output than the original Halogens. The 4 spotlight units – also warm white – had 15 LEDs on each unit, and cost $16.95 each (X 4). These seem as bright as the replaced G4s. They work fine for reading. The wedge base units had only 4 or 6 LEDs and were only $3.95 each (X 3)…noticeably less bright than the replaced incandescent wedge bulbs, but these are not primary lighting and (for me) work fine – really cheap, but I don’t think they are available anymore. You do the math. I bought these in two orders…first to see what they were…that they worked…and if they were OK…then the second order to finish up replacing all cabin lights. So it probably pretty much more expensive than standard incandescent and halogen lighting, etc., but then they SHOULD last a long time…and the current draw is much less!!!) I’m happy. All LEDs are still working a few months down the pike (well, down the river!). We’ll see how it goes next summer when I splash her and try all the lighting again. Hope this helps. I'm happy with the conversions. [/FONT]
