[Elecraft] OT - Magnifier lamp

[Jim Wiley]

I would like to get the opinion of Elecraft list members, particularly 
builders of kit versions of the K1, K2, and K3, concerning magnifier 
lamps.  These are commonly known as "Luxo lamps", although that is only 
the best known brand.  In other words, what are you using, how does it 
work for you, and what don't you like, if anything,


Things to consider:


Best magnification factor.   The most common are 1.75X (3 diopter) and 
2.25X (5 diopter).  


Size and shape of magnifying lens:  How big, and is round or rectangular 
shape factor best


Focal range:  how far from work is optimum, and what are close and far 
limits


Eyestrain:  distortion, clarity of lens,  adequacy of illumination


Illumination:   L:ED vs. fluorescent lamps - which is better / brighter. 
For fluorescent or CFL lamps, how long to reach max output


Positioning:  Best arm length,  does the unit "stay where it's put?"


Mounting:  Clamp mount,  robustness of mount.  Can the unit be removed 
from the base / desk clamp, etc.


Ease of working under the lamp/ magnifier:   Does the unit get in the 
way of soldering, etc.


Problems observed:  What could be done better


Special note:  In the interest of limiting OT traffic on this list, 
please reply direct if there are more than perhaps 6 or 8  posts to the 
list.  I know Wayne and Eric will appreciate it. 


Thank you.
