Airstream upgrading interior lights from halogen to LED is great, but why Airstream decided to use those hideous cool blue colored LED lights is a mystery.
During the day the cool blue LED light color is not so noticable. However, at night these LED lights turns your cozy interior into a cold, industrial cargo container - similar to alien ship interiers of many Hollywood movies.
I used color filters to give these cool LED lights a more natural warm incandescent-like light output.
I used a method described by another poster "flyingcloud".
Fixed! Airstream LED Color Temperature - Aluminarium
This method worked great and is very easy to do. The whole process took me about 2 hours for 15 interior lights.
1. Order 1 filter gel sheet from www.stagespot.com
(about $15 shipped to your door in a poster tube)
On the stagespot website select Manufacture = Lee and Search = Marlene
2. Use a pocket knife to remove the inner-most frosted glass lens holder from the LED light assembly.
3. Cut out two filters for each light. (I used one of the frosted glass lenes as a pattern)
note: cut 2 notches in the gels so that the filters will clear the 2 tabs holding the frosted glass lens in place
4. Place 2 filters into each lens and place lens back into the LED light assembly
Important: take care to line up the lens holder with the LED light assembly when re-installing - fits only one way - like a puzzle piece.
I was very happy with the results - natural warm color.
Good luck with your project.
