I used the expert setting and lowered the brightness to 20 - again, I haven't been real careful about making sure the TV is not defaulting back to a brighter setting.
you can use an ordinary desk lamp (like a clip on) and attach it to the back of your TV stand and just put a cheap 6500K CFL bulb in it (preferably with the highest CRI you can find)... this solution can be about $10
this is what my DIY solution looks like (see above)
as far as the TV's picture settings go, the 'brightness' setting only adjust the brightness of black and lowering that will not make the overall image darker but will kill shadow detail and make the dark parts of the image become a solid black blob (aka black crush or black clipping)
lowering the backlight is the best way to dim the image on an LCD (or LED-LCD) and the next thing to check is that contrast isn't set too high as it can make the brightest parts of the image lose detail and become a solid white blob (aka white crush or white clipping)
you can set brightness and contrast correctly with a basic setup/calibration BD or DVD and backlight can then be set to taste to make the overall image bright enough but not so bright as to create eyestrain
one more setting that affects overall image brightness is gamma... not much you can do with this setting without calibration equipment like meters/software but choosing the right picture mode on your set helps immensely (which is Cinema or ISF Expert 1/2 on your LG LCD)
