Incandescent or Fluorescent
Spot lighting is usually incandescent. A few use halogen bulbs, which are about 25% more efficient, but that isn't a very great difference. So for spot lighting, the choice is mainly just personal preference. Area lighting is a bit more confusing because you have a choice of incandescent or fluorescent, and they both have advantages and disadvantages. Incandescent lights are inexpensive, have a pleasant warm color, and are fairly compact, but they are very inefficient and give off a lot of heat. Fluorescents can be about four times as efficient, resulting in much less battery drain, and they give off far less heat. These are very great advantages, but there are some disadvantages. Some people object to the cold color of the light (even "warm white" bulbs are stark compared to incandescent), they are more expensive, the fixtures are usually over a foot long and they are often unattractive. We believe that Alpenglow lights have eliminated most of those problems and gained even greater efficiency. Quality does have a price, and Alpenglows may be more expensive; however, reduced engine time for battery charging will pay for it over time.
