Yes, there are a lot of posts on the forums about this, including many I've made. But, to summarize, I'm happy that I replaced all of my incandescent bulbs with LEDs. First, inventory what bulbs you need. I had about 15 CEC1141 bulbs in ceiling and counter lights. I went to Ebay and looked for bright, warm white, LEDs. I purchased some bulbs and some panels from a vendor in China. After trying them in the RV, we decided the warm white panels were right for us. I ordered a bunch of those, stuck them to the light fixture reflectors, and have been happy ever since! Now I ignore how much light we use when boondocking - they draw so little. I think I paid about $3 for each of my panels. Each panel has 48 LEDs (here is an example:

My advice: buy several different ones off eBay and find the one you like best.
