My experience with
LED lights for reading is that they don't give uniform illumination across a surface. If you want to check this out, many marine stores (I know the West Marine in Bremerton, WA does) have a display of a variety of
lights that work.
That is not to say that all
LED lights are equal, I'm sure they aren't.
The real advantage of
LED lights is their resistance to vibration failure, since they don't have a fragile filament heated white hot. As to their conversion efficiency from
electrical power to
light, I have read they are just so-so. Better than incandescent, worse than flourescent.
At about forty bucks, that's only about half a fuel filling on my Diesel Jimmy. If it doesn't work out as a reading
light it might be just the ticket for general overhead
lighting, then you could use a small halogen or fluorescent for reading.
It would also be a cool back-up
light.
Since I'm a early morning person and my wife is a late evening type and we both like to read, we have a couple of those book lights that clip to the top of a book page. Ours are LED, but have a special reflector that spreads out the light to overcome the blotchyness fairly well. You see them
for sale in book stores as well as other places.
