To match the existing old yellow-ish bulbs in color and brightness, you need 300 lumen brightness and color "warm white" or "soft white", with color temperature 3000K.
Some prefer cooler color in workplaces or kitchen counter - those would be 5000-6000K. Try 3000K first, this is what you've been living so far.
I bought this pack of 10, many people here bought from the same guy: $27, pack of 10
Only for a kitchen hood I bought a smaller plate, 12 LEDs per board instead of 24. I don't think that in RV dome light a "cob" LED would work any better than these SMD boards, and boards are cheaper than cobs. For a sconce light you need a "cob".
His Ebay storefront is huge. If you feel like browsing, double check before ordering to make sure that brightness and color are what you need.
As usual with China-direct buy, it took a month to arrive.
There can be such thing as radio interference - some lights generate noise on radio-frequency. Mine don't. Cheaper variety of LEDs usually don't.
Energy consumption - 4 times less than the old bulbs, my batteries are happier now. It says 3W, old bulbs were 18W, so it "should be" 6 times less, but it's 4 times.
If you are on shore power, there isn't much need to replace.
