Quick update:
Have made several more trips, and couldn’t be happier with both the light output/color, as well as the current drain (or lack thereof)! No issues with runaway heat, no issues with failures.
I have made a couple of changes/additions:
-I swapped out the 5-5050 bulb in the cab dome light with a 9-5050 for more light. Much brighter, and still 73% less current than the original incandescent.
-A two bulb (#1004 & #1076 bulbs) wall sconce lamp got unique “Tower(?)” style LEDs with built-in plastic hoods (to protect from dust), each with a measured current of 0.14A. Just for the heck of it, I got one in 3000K (85% savings over the #1004), and one in 6000K (93% savings over the #1076). The 3-way switch allows for either bulb or both to be used. Note: this is the only fixture where I used a warm (3000K) white, for just one of the two bulbs, and I still prefer the bight white over the warm white.
-Two final exterior locations got 13-5050 bulb style replacements (0.28A); the rear outside storage compartment housing the spare tire (80% savings over the #1141), and the small flush exterior work light near the black/grey dump (45% savings over the #89 bulb).
-Even the fridge light is getting in on the act, although I mistakenly ordered a “fusebulb” style when I needed a “festoon” style. Oh well, must’ve been an early “senior moment”? I will order the correct one, which will complete a 100% changeover in my RV.
For those of you who are considering LEDs, but still not sure...DO IT! They are cheap enough online (I prefer Amazon, but also got a few at eBay) that you can order a few of various styles to try them out before committing to any specific size/type. Many prefer the warm white, but my wife & I both prefer the 5000-6000K bright white (not the blue "cool"). Some may be happy with the 3528s, I prefer the 5050s (more light output). Ultimately, whatever type/size/color you want is available for very little money, so if you get a few you don't like, it's only a few dollars; nothing to lose sleep over. My grand total is still just around $130, and that inculdes more than 26 bulbs replaced! I also ended up with very few that I DIDN'T use; most that I didn't like for a specific application I was able to utilize elsewhere (refer to my original post). I now have 2-3X the light output at 1/5 the current drain.
