"LED lamps"
Yeah, and if you rub them the wrong way, the nastiest landlubber genies pop out.

"We have 60 cabin LED bulbs and 13 LED lights aloft. Even with all on at once, 0.4 amps."

That would be 73 LEDs drawing a total under 400mA. Making them less than 6mA each.

More likely, 2-3 amps in total, no? LEDs drawing 6mA simply aren't bright enough to be used for much on a boat.

Re: LEDs afloat

we have been hit twice in 4 years, once just before we bought. Last hit was July 5 in Muskegon Michigan. A direct hit vaporized the main mast Windex. We lost:
Wind instruments
boat speed
VHS
AIS
1.5 KW back-up alternator
3 of 6 spreader lights on two masts
all mast-head lights
all nav lights
all bow wiring was fused
3 LED bulbs in the bow cabin
transom paint was spauled
2.5 KW Xantrex off line (re-boot fixed it)
60 amp shore power breaker smoked

Curiously, the lightning arrestor was un-damaged

We have 60 cabin LED bulbs and 13 LED lights aloft. Even with all on at once, 0.4 amps. I haven't done the math but the diesel to charge & wear & tear on the batteries is the reason to have LEDs.

My observation: all lights, radio & any device should have its own local two-pole switch to interrupt totally both power & ground with an air gap. I installed our Simrad this way as well as its radar and depth scanner - no problems. This may not save everything every time but it is a definite preventative to induced spikes.

Re: LEDs afloat

The look forward will see better LEDs and if you have the expertise a 'driver' is advised. Glass in the bilge is always undesired end with bulbs since it is invisible to the eye, it is bound to occur.
The heat generated by the bulb is also a fire hazard. Fall asleep once and the batt is gone. LEDs are vulnerable but cheap.
It's my hope that my LED tricolor lamp is not going to put me through a replacement.

Re: LEDs afloat

That link to Bibe electronics (LEDs) in Fiji is is gone. A government take over there scared them off. You can edit message and take the link out, if you like

Multi-
I'm aware of all the pros and cons of LEDs, I was just limiting my response to what was said in one post. Carrying spares, and the cost of spares, is entirely separate from any question of power budgets and capacities. 100,000 hour life expectancy (for properly engineered devices) and potentially 20 fewer trips aloft to change a light bulb, or twenty nights not spent in the dark waiting for daylight to change it (G) all are separate considerations from the sheer cost of carrying spares for these fixtures.
Considering the way LEDs and their prices keep improving? No spares, gamble on needing a new one in five or ten years. All other considerations aside.

Re: LEDs afloat

Hellosailor,

You might consider, when you do your expense calculations, to include the extra run time for power generation you'll need for those consumptive incandescent bulbs.

And speaking of 'knowing where to buy them,' there are plenty of good quality LED around that are far less than the prices you're citing.

Having experience with LED (my entire boat is LED) I have found them to be neither particularly sensitive nor particularly expensive.

Re: LEDs afloat

The problem with standard bulbs is more than just outage.
The amount of pull on the battery is as much as ten times that of LEDs.
The free standing solar powered LEDs or the batt types can be adapted and since they are not hard wired, do not suffer the damage from lightening.
Interesting point though.
(A boat rarely has solutions. Only extenuating circumstances).
