-====== LED lighting ======
-RVs and campers, particularly older ones, are generally provisioned with incandescent bulbs.  Replacing these with LED lighting can reduce power consumption for those fixtures by about 90%.  Because of this they dtend to run cooler.

-LEDs tend to have cooler/bluer color than incandescents, which are yellowish in comparison.  First learn what color you prefer (expressed in degrees Kelvin) then select LEDs in that range.  Some sample color temperatures:
-  * 2000K - candlelight((http://www.planetbulb.com/pages/What-is-Kelvin-Color-Temperature%3F.html))
-  * 2700K - 60w incandescent, seen right
-  * 3100k to 4500  - bright white((http://www.westinghouselighting.com/color-temperature.aspx))
-  * 5000K - daylight (scientific [[https://en.wikipedia.org/wiki/Standard_illuminant#Illuminant_series_D|standard illuminant)]]
-  * 5500K - bluish white, seen right
-In order from best to worst:
-  * LEDs in fixtures designed for them
-  * Panel-style LEDs in incandescent fixtures
-  * LEDs that copy the form factor of the incandescent bulb they replace
-===== caveats =====
-LED lighting can be sensitive to the higher voltages associated with [[electrical:12v:charging|lead-acid battery Absorption and Equalization stages]].  Campers may want to run LED lighting power through a power regulator.
