What replacement bulbs am I looking for?

Hey forum,

My girlfriend and I have are living in a 33ft Nomad Travel Trailer. I believe the year is 1988. I have attached a photo for reference. We bought the trailer a few months ago and renovated the inside and all is pretty good so far, however we need to replace all of the interior lights now and I'm not sure what bulb type I am looking for.



We are currently getting out electricity from 400w of solar panels so I'm hoping to get some LED's in there.

Any tips in the right direction would be great.

    How do you find the LED light vs the incandescent. I see the lumen output of the led panels seems rather low and Im curious how they compare. Your panels specifically seem lower than the 48-5050 panels I was looking at. How do you find your led replacements?


    I find the light from the 36-1210 LEDs that I bought very close to the 1141 bulbs they replaced. I also bought some 36-1210 from a different vender and they were much dimmer and much poorer quality, and cheaper.

    I guess it depends on your reason for converting to LEDs. I did it to reduce the power consumption. The LED panels I bought draw about 0.2A. The 5050 LED is actually 3 LEDs in the same package, are about 2x as bright and draw about 2x the current. Of course, the current drain depends on the series resistor If the resistor is a higher resistance then the current will be less and the light will not be as bright. All LED panels are NOT created equal.

    LEDs are directional. The panels direct most of the light down and while the lumens may be less, the light in the area lit by the LED will be quite bright. Lumens is a measure of the total light from a source. BTW, I don't trust the advertised lumens on eBay.

    The only way you will know if a particular light is what you will like is to buy 1 or 2 and try it. There are differences in the fixtures, differences in the series resistors and differences in the LEDs themselves.

    Hope this answers your questions.

    It does. Thank you and to everyone else who chimed in.
  • Just in case you didn't realize it, the 1210 and the 3528 LEDs are the same thing. 3528 is the metric size while 1210 is the US size. 5050 is metric.

    400% Mex import tax on Chinese items, yes, but if you bring it with you from another trip North, they don't care - too much - whether it's made in China or not, and besides, there is an exemption on the first $75 PER PASSENGER. So if you and your friend both go North and then back to Mex, you can bring $150 tax free.

    Also, there is a good US store: http://www.commandelectronics.com/led_bulbs.html

    Your "old" bulbs, whether 1141 and 1156, have same BA15s base, only the wattage slightly differs between the two.

    In LED, the biggest problem (besides unpredictable Chinese quality) is - unknown color. You get 6 bulbs and 1 or 2 may have slightly different shade, even though all 6 are supposed to be the same "warm white". Still, pay attention to color temperature in specs. Warm White or color temperature 2700-3500K is - usually - the shade close to that of your old bulb. Bright White or Cool White and higher K number means farther from yellowish and closer to bluish.

    There should be a number on the base. The 1156 bulb is a standard automotive bulb. The down side is the put off a tremendous amount of heat. If you go with a standard bulb, use the 1141. If you can afford the LEDs use the link above
  • I bought a bulb direct from china for $3.00 ea from e-bay. It is a direct replacement and brighter than 1141. Ba 15, 102smd that is 102 led panels on the bulb. about the size as my index finger.
  • add to previous post, seller is, 3c-made-in-china (ba15s 102smd led 1156) also selling cool white but I have not tried the cool white.
