Why don't you buy a few different ones and see what works best for you? This isn't like replacing $100's of dollars of batteries, just a few dollars for experimentation.
A few things I've found out about LEDs: Not all Kelvin color ratings are the same. Even same configuration of LED's in panel or cob may differ in color between vendors. Not all lumen output is the same. Even between same amount of LED's on panel or cob between vendors. Light output is very subjective between individuals, what I like may not be what you like or even discern as the same or different output. LED's are dependent on the voltage to the device. My light wiring may run at 13.2 vdc. I have no idea what anyone else's is. LED's save a huge amount of power and are one of the best upgrades an RV'er can do. Horror stories about LED heat issues are anecdotal and there is usually something else at play. They run at far less heat than an incandescent. LED's have a much longer service life than any other source of electrical illumination (I had to put the "electrical" in that last because I know someone out there is still using his original propane mantle).:B
