I only installed it a few weeks ago so I can't comment on durability. My main concern is if they will be too bright. You are exactly right. I made a change to extend battery life when dry camping. They reduce the electricity for lighting by about 80-90%. If you want to change the bulbs in your RV, count them first and check the bulb base type. There are more light bulbs than you think and they don't all have the same base. Thanks very much!
