Light Bulbs overheating????

Trying to figure out posting pic!!?!?!?!?!?!

Use this to post pics. Picture posting

Just replace them all with LED lights.

You might want to check the voltage being applied to the lights. It should be under 15v when plugged in, and depending on your converter, may be as low as 13.2v.

This!

Ok, there are two light bulbs I will use for example

1141 and 1156

These bulbs appear PHYSICALLY identical and both fit the same sockets...

the 1141 is 19 watts, and the 1156 26.. If you replace the smaller (1141) with a 1156 it will cause overheat.

That said, I'm not sure the 1141 won't


Solution: LED replacement.

All the original bulbs inside our 2014 Coachmen Freedom Express were incandescent 921 bulbs so I replaced them with LED equivalents that are bright ( ~300 lumens apiece), good colour (~3200 degress Kelvin), don't interfere with the radio, and run cool.



However, the exterior light fixture by the entry door had an 1141 incandescent bulb that got so hot it melted the fixture itself ... it was replaced under warranty and I installed an 1141 LED version, no more issues since.

This is post from another forum I found interesting about RV bulbs and the difference between the 1141, and the 1156.

""No, clear or not has little to do with it. Watts (power consumption) is what produces heat and an 1156 uses about 50% more watts (and amps) than an 1141. An incandescent bulb produces light by "burning" electricity, so the watts are converted to heat in order to produce light. More light = more watts = more heat, all in proportion.


Here is a more technical answer
Both the 1156 and the 1141 are Single eliminate bulbs using a BA15s single contact base. The glass envelope is a S8 on both. So they are physical the same size and would use the same electrical socket.

The difference is in the element. The 1156 is a 12v 2.1 amp 26.9 watts unit with 1200 hrs life. While the 1141 is 12v, 1.44amp and 18.4 watts with 500 hrs life. The 1156 produces 32 candle power while the 1141 produces 21.

The 1156 will produce more heat than the 1141 and that will require a slightly different design for a mounting fixture/lens cover/shade. Said a little differently the 1156 in a 1141 housing may melt the lens cover/shade.

As to the use of an LED in a mount designed for either bulb I doubt that any problem from heat would be encountered using either. The LED for the 1156 would have more lumen's than one designed for the 1141.

It comes down to what is the requirements in lumen's for the application.""

Sounds like the wedge type bulbs #921, those get so hot they will remove your finger prints and the turn black inside. I replaced all of mine with LEDs. :)

So happy our new one came with all led except the dinette slid out light and by the couch. If possible those will be switched out by our longer August trip too.
