LED

[no one that you know]

Awhile ago I talked about converting my RV too CF lights.
All I did was put a yellow bug CF in my trouble light.
Instead I went all LED and I am very glad I did.........I love
them.....23 led lights in all.......light where I want it when I want
it.
All of them on all at once and the draw is very little about 1.9 amps.
Going to remove the full size car battery to reduce weight and go with a
moter cycle batt instead. Prolly all I need for power now and can bring
that up to a full charge quicker than the big one. Beside these 12 volt
LED still give off plenty of light even when the batt drops down to
three volts. Any comments?

I hope you don't really allow your battery to drop to three volts.

Yes you'll wreck a lead acid batttery by doing that to it in no time.

You need a decent size battery to crank the engine to start it btw.

Deep cycle batteries are designed to do that. Some are designed to combine
deep cycle performance with starting ability also. A bank of golf cart-type
batteries will also work for both purposes.

Those must be different than the ones I tried. They clearly had 1156
stamped on them, supposedly an equivalent to the standard automotive backup
bulb. The output however, was barely sufficient as a nightlight. Without a
light meter, I'd estimate about 5-10% the usable light output as the
incandescent it was supposed to replace.

I'd like to see some figures on the lights you have, because last I checked,
there weren't any white LEDs available that were much more efficient than
incandescents.

Canadian tire the boating section go figure and ebay for the 1157 led style.

Not yet but I will thats why I am going with a cheap moter cycle batt.
I tested the 12 volt led's with a AA.

They are not nearly as bright but that is why I added them all over the place.

Discharging batteries flat is really bad for them, and replacing even a
cheap battery because you ruined it is a really expensive way of doing things.


Perhaps someone here can suggest an inexpensive low voltage disconnect
module.

if you are dropping a 12Vdc Battery to 3Vdc under load, then you
are a "Mooroooon", (bugs bunny definition) and deserve exactly what
you get in battery life.........

NO battery is "Designed" to discharge from 12Vdc Designed Power Point,
to 3Vdc Designed Dishcharged Point, and anyone who tortures a battery
in this manner, will get exactly what he deserves......

A Dead Battery........

Where do you guys come up with this stuff.......

 

[You]

Where did you purchase the LED units?

The OP got them from "Idiot's R US", where he also got that great
battery discharge advice............

Don't you think it might be a bit better to educate the OP rather than call
him names?

I think what was originally meant was a 3V drop, not a "drop to 3V."

An LED that is wired for 12V, will not light properly at 3V.

LED's, good idea, but running your battery down to 3 volts will
destroy it quickly. You should not go below 50 % discaharge before
recharging, and I belive 50 % is somwhere around 10 volts.

I just checked the AH rating of motorcycle batteries, and they seem to range
from 12-17 amp-hours. If you're drawing almost 2 amps, would you be happy
with 4-6 hours of light?

When that MC battery dies, get yourself a SLA battery. They have spade
terminals, and are commonly used in UPS's. No fumes, and they last longer
than MC batteries.

No matter what type of 12v battery you use, never discharge it below 12v.
That will ruin it in no time.

Deep cyle batteries are designed to withstand deep cycling better than
standard lead acid batteries, but discharging to 0.5 volts per cell
will destroy even thew best deep cycle batteries in relatively short
order. DO NOT DO IT!!!!!
80% DOD (Depth of discharge) is the very VERY lowest I would
reccommend. Even then, battery life is significantly reduced over, say
70% DOD.

I converted my RV to LED's too, very happy with them. my incandescent light
fixtures have 1 led bulb and 1 incandescent bulb, the switch turns on the
LED bulb first and then if you slide it father the incandescent bulb will
also turn on.
