As one who likes to dry camp, I am always looking for ways to conserve battery power. In the past I have always converted several of my fixtures to florescent. This is a big help. I have found a LED bulb that I am playing with. (www.jclampstand.com/
). These are a 11/2inch grid of 36 LED bulbs and fit quite a few different sockets. They do give a little blue cast but at night they illuminate fairly well. The lumens are not very great per bulb, and they cost $20 each. That is still cheaper than a 12 inch 2 bulb florescent. However, the florescent will give as much light as an incandescent fixture with about half the current draw. LED's pull very little. I am still going with a couple of florescent fixtures, plus the florescent over the sink. I think the LED's will be useful in an area where you might want some light, but intensity is not critical. If you dry camp for very long, you just can't run very many lights. With light management, I can usually last 5-7 nights without shore power or a generator. I use 2 deep cell batteries.
