I'll bet it was the bulb in the refrigerator that did it!

JimH,

This is exactly what I need, it uses one tenth the power of a 12 volt
bulb.

I saw that there were some all around LED lights to replace the 12 volt
bulbs, but they were substantially more expensive, and only saved 1/2 the
power.

I forgot to mention that the Gel Deep Cycle battery also powered the
refrigerator, so that is probably why it always died during the night.

JimH,

I have a deep cycle gel battery, When I use my anchor light, it has
never
made it through the night without being completely discharged. Is this
normal?

First version, otherwise why use 6 resistors instead of one
single
lower ohmage one of higher power.


I was trying to roughly calculate the power requirements. You
said
600 ohm resistors, correct? The voltage drop on the LED will be
minimal when forward biased or "on", so each branch must be about
.02 amps, times six equals .12 amps, so the power must be about
12v
times .12 or about 1.4 watts. Probably a bit more when you factor
in the LED drop, whatever it is. Significantly less than a regular
light bulb!

Eisboch


Most LED's are in the 400mw range.


How about the standard 12v bulb used for anchor lights?

I don't know what their wattage rating typically is. My guess would
be
somewhere between 10 - 20 watts, given that they are required to be
seen, what, 2 miles away at night?

What is the benefit for a boater on the hook overnight besides having
a
brighter anchor light? Is there a significant less draw on the house
battery over a 10 hour period?







I never had that problem.

Something you can consider is a portable anchor light such as this one

The one on my boat is "maybe" visible at 2 miles, in complete darkness
you can see a pin prick of light but it's so tiny you're not sure if
it's just what you see when you look that hard at the dark:-) but by
well over a mile it's definitely in play & by 1 mile very clear.

Here the pleasure boat rules just require "visible" at 2 miles.

What brand of LED are you using?

There are some (pricey) LED lights made in the Netherlands, called LOPO
lights, that are certainly a lot brighter than a standard bulb. I first
noticed them about a year ago at a boat show and they appeared
dazzlingly bright even in an indoor setting with a tradeshow light
level.

You could probably get a "deal" on some if there isn't currently a
distributor in AUS.

Since my boat came with 2 batteries, and this is similar to most of the
smaller cruisers I have seen, how do most people handle the refrigerator at
night, do they only keep it on when the engine is running?

Without some major work, it would be hard to add a 3 rd battery in the
bilge.

Without a generator, a cooler and lotsa ice is your best bet. A refer will
kill a group 24 or 27 battery in about 4-6 hours.

We never had a problem running a refrigerator while away from shorepower
overnight. But the boat had 3 group 31 deep cycle batteries though.

Ok, I guess it is time to get a new boat with a genset.
Thanks for the help.
