Nandy,
If you are using the Oscilloscope application in the tinyos-1.x/apps folder, all of the readings correspond to the light sensor by default (ten 2-byte readings). The format is little-endian, so you need to reverse to order of the bytes, therefore your data is:
0x0396,
0x0397,
0x0397,
etc.
which corresponds to: 918, 919, 919 in decimal. These are ADC readings in reference to the 10-bit full span of the adc (1024 max). Take a look at the documentation on the crossbow website for more information on converting your sensor readings into meaningful data or take a look at the tinyos-help mailing list archives on www.tinyos.net
