Replacing interior lights with LED's

how about some links to the bulbs that you have as replacements or the LED arrays that will generate enough light for reading.  

A great way to shed some load, thanks for the info.

In an effort to maximize the battery life for our annual week-long boon docking trip,  I recently ordered some LED's to replace the interior lights. We finally had a weekend to go camping, so this project was at the top of the list. Since I already had the multimeter out, I decided the check the current draw of the regular bulbs vs. the LED replacements. Wow-- what I found was really surprising.

***The fine print: These LED replacements are about 1/2 as bright the standard bulbs. They are adequate for eating or playing a game, but it might be difficult to read something with, uh, fine print. I just went back to the website (superbrightleds.com) and ordered some larger LED arrays that will generate more light. I'll report back when I have a chance to test these.

I turned on one of the double overhead lights (RP177) and found it used 2.460A. I replaced the bulbs with the LED's and remeasured the current at 0.040A. Thats less than 2% of what the std bulb used. Thats huge!

So let me put this into a battery life perspective. If you have a 75Ah (Amp*hour) RV battery, you could estimate that it would sustain a load of 1 Amp for 75 hours (under ideal conditions, battery capacity is effected by load, other factors effect capacity, your mileage may vary, blah, blah, legalese). Using the numbers from above:

std bulb:      75A*h/2.460A => 30.5 hours of use
LED array:    75A*h/0.040A => 1875 hours of use

Thats a BIG difference.
