I have exactly the same problem with a DELL 2007 WFP monitor. 
There where no problems before but, now using Spider Elite 4.0.2, all the sudden I get the message 
“Brightness target  adjusted from 120.0 to 88.0” and that is a very big difference. 
For your information the “ambient light option is OFF” and the calibration setting (when I started calibration) are: 
FULLCAL, Gamma2.2, White Point 6500 K, Brightness 120
remark:
When I leave the Sensor attached to the USB-port I see the blue-led on the sensor going on and off, so it looks like the ambient light routine, although switsched off, is still working. 
Greetings,
Wim

The Spyder3 tells me that my monitor is not bright enough - with a target of 180 it reads my monitor at 74 at 100% brightness and sets the new target at 74. The final profile then dims my screen so much that I lose all detail in blacks/grays. It is a HUGE difference. For example, on the Spyder3 menu screen with an uncalibrated monitor I can see that there is a pinstriping effect on the black background. After calibration this becomes solid black, as does anything else that has shades of black/gray. This was never an issue with my Spyder2 so I don't believe there is a problem with my monitor, certainly not to that degree.

You neglect to tell us what version of Spyder3 software you own, or what settings you are using. It could be that you are running the ambient light check, and your room is do dark that it is trying to get your display dimmed down to match. If you turn off the ambient light option, set the target to 120 candelas as a white luminance (brightness) then it should calibrate to that level, and be a good moderate brightness. Give that a try before moving on to other things.
