    Peter,

    It is hard for most models
    to direct any such light to the
    place on the scale where you read.
    
    > they tend to be too bright,
    
    There are some where brightness can be adjusted.
    I use an LED light from Celestaire. It has a clip,
    which can be attached either to the sextant frame
    or to your hat.
    The light direction can be adjusted with respect
    to the clip. Costs $15 to $20 and
    comes in
    variety of light colors (I use red).
    
    Still is it not as convenient as a built-in sextant
    light.
    
    But I agree that for practical boat navigation
    the light is not necessary. You usually take altitudes
    during the day or twilight when the scale is usually
    readable with natural light.
    
    I do a lot of lunars when it is completely dark,
    that's why I need a light.
    
    (SNO has illumination by luminiscent paint, but it does
    not work well enough because the sextant is 17 years old and
    the paint almost lost its properties).
    
    Alex.
