Hello,
We have a 2006 Fleetwood Niagra and am trying to figure out the total amp hours that my pop-up uses.
Can someone tell me how many amps or watts my bunk end light/fan combos are? (It doesn't say anywhere on them.)
Also, none of my light bulbs have any information on them as far as watts either?
Any help would be appreciated.
Thanks!
POTC

You should be able to hook up an inexpensive volt meter and test each source. I did that with my unit and that info has helped in determining my battery draw down during dry camping.

Google can be your friend here... Just type in the part number into google and look for specs... i.e. your ceiling lights in your POPUP are most likely using 921 bulbs... Goggle says this draws 1.40AMPS.... My POPUP has two ceiling fixtures each with two 921 bulbs being used. I also have a single lamp fixture over the sink area which uses one 921 bulb. So that adds up five 921 bulbs being used or 7 amps total. Replacing the 921 incandescent bulbs with LED boards is suppose to a 80% power savings which would relate to a 5.6AMPS savings (if my math is ok)... That is a hugh battery savings effort. you can see from this how much savings you can get by just replacing all of your ceiling light fixtures.
Another useful meter you use is called a KILL-A-WATT meter model P4400. This is one you plug into a wall socket and then plug an appliance into it (Like a 120VAC FAN) and it will tell you what the current draw is for that appliance. This is the 120VAC side of things not the 12VDC side unless you are running an inverter which runs off your battery...
Just find the devices you need info on like the fan and light combo and just type that info into google search and it will tell you something about it... Hopefully you can find the specs of the unit by searching its part number.
There are also alot of info on the internet that can found on general 12VDC items used in RVs that list the amount of current they draw. I think the 12V SIDE OF THINGS is an article that has a bunch of items listed and how much current they draw. Dont forget now your operating voltage is usually 13.6VDC not 12.0VDC so if you are trying to calculate this be sure to use 13.6VDC verses 12.0VDC
Using google search just type in plain language and ask a question. i.e. type in "HOW MUCH CURRENT DOES RV APPLIANCES DRAW" and see what you get... (I havent tried this yet haha)
***Just looked got lots of hits to go look in.... If you select "IMAGES" on the ;eft side of the screen you may see alot of charts to click on...

Thanks for the feedback.
I did google the fan/light combo and found it, however it doesn't have any info on amps or watts.
I'll try the bulb next.

I did just find info on the lamps. (Still not the fan though)
In regards to swaping out with LED's. I have been kicking that around and am wondering if anyone has any recomendations on "Warm" replacement LED's. (the lamps I currently have are 1141 12v21CP.
Thanks

I have done a full LED replacement in my '06 Fleetwood Sequoia, including the fan/light units. I prefer the warm white LEDs over the cooler/bluer LEDs. It's personal taste.
It makes quite a difference inside on the light quality as well as energy consumption, depending on what you use. This time of year, I am grateful for anything that doesn't add to interior heating.
Ebay has tons of cheap SMD LEDs. I have a few of these but they actually ended up being my "nightlights" for my dual-bulb overhead fixtures, of which there are three. I put the $5 specials for when the lights are in the "single-bulb" mode, and the $25 boards in the "dual-bulb" mode for lots of lighting. The 30 SMD units are from CommandElectronics and I've had them for about three to four years now with good results. My PUP was a bit dark in an area of the seating and these boards help make up for that.
Or, I can just run off the single-bulb modes for greatly subdued lighting and subsequently even greater power savings.
The only incandescent I have left inside is the refrigerator 3 watt bulb, and the marker lights that run off the TV anyway.
The 1141 bulb is rated at about 260 lumens and 1.4 amps. The CommandElectronics 30 LED board is rated at about 510 lumens but at .47 amps. Twice the light and 1/3 the draw. I would say it is perceptually much brighter, especially since all of the light is down-firing instead of radiating out in all directions as in the incandescent. I don't have the specs on the cheaper boards handy.
I transferred all of the LED boards from my first PUP to this PUP when I sold it. Even if I had to do it all again, I would.
I would suggest boards that are built around the 5050 SMD LED, which the total SMD count comes in multiples of three. These are the largest sized individual LED chips generally available in automotive type lighting. High chip counts but small sized chips don't equal decent chip counts with large sized chips. Size and count make a difference.
YMMV.

Second looking at the '12 volt side of life'. We dry camp a great deal and I went about figuring how much everything used some time ago. I took the next step and got a 2nd battery and solar panel.
In my case, I have all the manuals and they all show power draws. A good starting point is that every light bulb in your pup draws 1.5 amps. So. if you have fixtures with two bulbs in them, you're at 3 amps per hour, per fixture.
I'm not sure if someone mentioned it or not, but you have constant (small)draw from your propane detector and possibly other appliances. If you're looking to save on amp hours, you want to disconnect your battery during the day (or get a switch to turn off/on).

Thanks everyone for all the info!
@ red31- That is our light/fan combo. (I would have thought it would draw more than 1.3A?)
I did purchase a 2nd Group-29
I have (1) LED board on order to check out the fit and results before i get more.
Just recieved my new 70watt Solar Panel in the mail today!  A friend of mine gave me a controler and and all the cables and connectors needed to hook it up. Heading up north camping in a couple hours. Excited to try everything out.
Thanks again!
