Here's something for consideration about LEDs:
How many of us have lights in their fridges? I noticed in the relatively short time the door is open, two things happen. First, the bulb gets very warm (hot), and the fridge will have to work to coll the bulb back down after you shut the door. Second, for the time the door is open, there is a draw on the battery. If you open the door many times during the day, there will be a noticeable power consumption. The door may only be open a couple of minutes at a time, if that, but eventually that time will add up.
So, I pulled out the old bullet light bulb in ours, and installed an LED in its place. It's more than bright enough, and a bunch cooler. I singed my fingers removing the old bulb, and the door had only been open maybe a minute when I grabbed the bulb. It's part #F4LED-BW on
