The rule of thumb is to get LED that are around 380-500 LUMENS and are of the WARM WHITE color which should duplicate the 40 WATT indescent bulb. I also am using the LED board from Ebay/China for 4.99 a board. They stick up inside the ceiling lights and have the adapters to plug into the 12VDC.
Dont go buy a bunch of any of these until you get one that works good for you. Just buy ONE. If they dont list the LUMENS then they are probably not bright ones... A whole bunch of info on here just search for LED...
You will get an 80% power savings switching over. A REALLY BIG DEAL actually for camping off the power grid...

The 1156 102 LED bulbs are a good choice.....and low cost. I had 4 of them arrive yesterday. Inside the TT they gave a bright white light with a slight tinge of blue. Outside in the porch light, etc, they gave off a very bright white light that was good for illuminating the surrounding area. That's where I'll use them.
I was looking to replace the florescent fixture over the TT sink. After much research, found the new Kaper-11 fixture LEDs. Perfect in my opinion. Double and single models available. Even a single unit with a Night Light built in. The light given off is a soft white light with no blue tinge. The lens cover has a pattern etched into it that helps soften the light and spread it out. Yes, replacing the whole fixture is pricey but I only have 4 to replace, so the upgrade will be worth it to me in my '05 Bigfoot. And they're on sale right now at Panther RV.
I purchased a bunch of these exact same lights from the same vendor on eBay...actually three separate orders. I'm really happy with the lights. They are very bright. They are a "warm white" - not exactly the same as an incandescent bulb, but close enough to keep my wife happy. What I really like is the low power draw when we're boondocking! I have no hesitancy in purchasing more of these lights if needed for something else.
