There are several good threads on the two Casita
forums (Casita Forum.com & Casita
Club.com) about LED replacement bulbs. Based on info there, I replaced all the 12v lights
in my egg with LEDs. You can get "soft" white which have a softer, more yellow, more incandescent look to the light and you can get "cool" white which is very bright blue/white. We use the cool white over the sink/stove area and the warm white over the dinette for reading, computing, etc. Also check the lumens rating. I found some flat LED flat replacement "cards" with 9 LEDs on them that were rated at 120 lumens while some 16, 24, and even 36 LED flat units were only rated at 92. That made a big difference in the amount of light. I also used some of the bulb-shaped LED replacements for bathroom, over the bed and for the outside fixtures. I wanted to try all the various configurations. I may keep a mix depending on which fixture it's in or at some point I may replace them all with the ones I like best and that work out the best. One great advantage to LEDs, though, the LEDS really reduce power draw from the battery
. I've been very happy with the results. Also, it's a mod that I could handle. Both the flat LEDs and the bulb shaped ones had the standard 1141 bayonette base so it was a simple unplug the old and plug in the new. Even i could handle that one!
Also, some folks replace the standard, translucent plastic diffuser on the fixture with clear ones to get more light. I found in unnecessary to do so as we felt we got adequate light through the stock, translucent diffuser. Also Bargman now makes LED replacement brake light fixtures for older trailers that originally came with incandescent ones. Much brighter and a bigger, more square "light" pattern when braking. Our newer trailer came standard with the LED Bargmans and it is amazing how much brighter and crisper the brake lights
