Change over to LED bulbs

I am looking at possible change out to LED bulbs. My current ceiling lights are typical dual light bulbs with the number 1141 12V21CP with standard bayonet ends. In looking at SuperbrightLeds.com all I can find are marked 1142 leds with bayonet ends . What bulb would be best for the ceiling application as far as brightness and light color and which will work in the fixtures I now have. Any advice is appreciated, thanks.

Many (most but not all) LED's are blue to white (not warm light) and similar to the old florescent office lights in color output. If you like the light color of your current bulbs light then try to get bulbs in the 2700-3200 kelvin range. I would just buy a few samples before committing to a large purchase to make certain you like them. After all you'll have them a very long time.

Here are some other places that you may want to look for LEDs. We did buy some replacements for some of the ThinLites from MarineBeam and they are very bright.

I would have agreed with this a year ago, but these days there are plenty of "warm" LED lights.

We had a Thinlite 12" fixture with a failed ballast and replaced the bulbs with these and have been very pleased: Ming Natural White 12" 300L RV LED Tube for Fluorescent Lights

If you have fixtures with a relatively flat surface, I would look at the ZipLED's at PrudentRVer.com. They point all of the light down, not into the reflector. They are peel and stick, and can be mounted to flat surfaces. You can put in multiples depending on the space you have available. I have four of the ZL3's in a bathroom light fixture, and 6 in the scare lights. They have a bayonet base you plug them into. They have a nice white light, not bluish. Beats the light output of the weak 1141 bulbs. Better light with no heat and lower amp draws as well.

When shopping for LED's, pay attention to the lumen ratings and the light temperature rating. A PPL chart shows the 1141 rated at 104 lumens.

Thanks for the help and the new places to look for the lights. I will combine this info with what I have been previously given and hopefully make the right choice for the lights. Again, thanks.

The February issue of Motorhome magazine has a pretty good article on LED lights. It starts on page 60.

I replced my 1141 bulbs with these:
Star Light Revolution LED 300 White

They are pricey but I am very satisfied with the light they put out. I tried some others but they did not work due to polarity problems. I didn't want to rewire my fixtures and these are not polarity sensitive.

I've tried to switch over to LED bulbs, my wife hates the color temp of most of them so I haven't been successful yet. Still looking though so keep the links coming!

We used these in ours and think they look and work great, a lot pricey, but we have tried many and in our opinion these were the best.

Warm White LED Upgrade Kits for Command Interior Lights
Finally! LED's that are truly bright enough to replace bulbs and the perfect warm white color similar to incandescent bulbs. Each of these boards contain 30 extremely bright warm white LED's delivering 510 Lumens. The light output is 42% brighter than the standard 921 bulbs used in our interior lights. Electrical draw is reduced from 1.4 amps per bulb to 0.47 amps per LED board. And each board runs 150 degrees cooler for increased comfort when camping. Simply unplug your old bulbs and plug in the new LED module. A new lens is included for best optical output.

These modules fit Command Electronics lights. They may not fit other brands.

Sorry ti hijack but how much longer could my batteries last if I switched to led's? I have about a dozen (from memory since she's in storage) I'm replacing my batteries in the spring and need to get as many hours from them as possible. We're going to Yellowstone in july and several campsites have a no generator policy.

I put a set of these in our TT before last season. I used the superbrightleds with the slightly yellow color code on the website. On many of the bulbs there they have a blue, a white then the slightly warmer yellow. Choose the yellow. Those seem to me and more importantly the DW to have the correct color. I only ordered four and put them in the bedroom to test. Very good brightness and color.

As for energy savings. The original bulbs drew almost 3 amps per fixture. LEDs draw 0.2. That is huge in the morning when my solar starts to charge the batteries. We will replace all of the bulbs this off season. If you are trying to boondock you need to consider this. I took a dual approach: install solar for power and then conserve. With the solar system I installed, though, it isn't strictly necessary to conserve as much as we do. Old habit die hard though!
