Using camper energy savings ideas (LED) in your house?

I just converted 80% of my camper lighting to LED.
Bought a sack of 24-diodes LED panels, each with 3 adapters for different bulb sockets and I paid $1.05 a piece with free shipping from China.
Anyway, like the panel idea as not only I could multiply the panels inside my old fluorescent housing, or stick it higher inside refrigerator what not only save energy, but give much better light.
With 12V it is easy as you don't have to worry about exposed wires.
Now I took a look inside my household refrigerator and it has 2 powerful bulbs in freezer part + 3 in refrigerator part.
The freezer light, being on the side of top shelf sucks as well as taller food package covers most of it.
My worry about bulb energy use is secondary as they come only for few seconds with door opening, but they look like 40 W incandescent bulbs, so they also generate quite a heat, what freezer has to absorb.
Meaning puting LED there would gain pretty good energy saving and would extend compressor life as well.
The problem is that those are 120V, so you can't have wires exposed and the original bulbs are pretty small in diameter with weird sockets.
It is smaller than regural bulb socket, but bigger than my chandelier sockets.
I think for this application to use LED I would need smaller power converter and than I could use the leftovers in the sack of LED I already have.
But nobody makes converters that just screw into light bulb socket, so did anybody figure out easy way to do it?
I would not worry too much about cosmetics, but want it to be safe.
How LED take 0F anyway?
  • You can use camper energy saving ideas in your house by always buying the pre-cooled beer. Works every time. :)

    I just replaced eight 50 watt halogen bulbs with 6 watt LED's. They came directly from China. Two of them quit working within ten days.
    Fortunately I bought a couple extra.
    It saved energy but, not much money yet.

    good points about options for energy savings going endless.
    I know a guy in CA, who has 6 tons concrete heat accumulator buried in his backyard. Solar water panels (cheap) heat it up in the afternoon and he draws the heat for water and house warming at night.
    All he pays is for very small energy the electric pump draw.
    But those are pretty expensive and complicated ideas, while light bulb exchange was plug&play in my camper. I am trying to make it as easy in household freezer.
    Than I would add some to your energy calculation. When you have poor light in the freezer, you keep the door open longer. The energy useage can multiply very fast.
  • I just check the converter my LED strip has. It is 2x4x1.5" and black.
    Worse come to worse I could hardwire it inside freezer light housing, but it is not going to be good looking.
    Than I would have to do some low temperature testing.
  • Well, if you really want to go for, all of those products already exist. Costco sells all sorts of LEDs, even ones that look like florescent shop light. And of course, just use mr. google to find just the replacement bulbs themselves for just about anything.

    Going green is commendable, but...

    There is a common term called ROI - Return on Investment. How long will it take to get your money back on the money spent.

    Here in PNW, we pay roughly 10 cents a KW hour. You run an appliance that draws 1000 watts for 1 hour, you pay 10 cents.

    Lets say your new bulb for the inside of your fridge draws 30 watts now, about what those little bulbs draw. You put in an LED that draws 5. You saved 25 watts every time you open the door. We'll say that single LED bulb ran you $5.

    Now--
    It saved you 25watt-hours.
    Each Kilowatt hour costs $0.10
    You paid $5
    At $0.10/KWH, you need to save 50,000 watt-hours to break even.
    At a draw savings rate of 25 watts per hour, you need to run that bulb (with the fridge door open) for 2,000 hours to get your ROI.

    Hopefully you won't leave the door open on your fridge for 2,000 hours....

    Now if you REALLY want to save money on your power bill, focus on things that produce heat-- I just bought a brand new heat-pump hybrid water heater for my house. An average water heater uses a pair of 5,000 watt heating elements. This draws 2/3s less to heat the same amount of water because it uses a heat pump.

    Regular $1,399.00

    Yeah, I have them in my chandeliers, but they are bigger bulbs that will not fit into freezer light housing and even for dining room chandelier I had to buy socket adapters as the US size was not available.
    Than having converter I could put small LED panel at each shelf, what would give me superior lighting.
    I am also thinking about possibility of using LED strip. Have one of those over my cooktop and with color change it makes nice impression, although light output is smaller.
    Main problem is finding converter that would easy connect to old light.
