You need to check the temp with a thermometer to see if it's in a good range (88-90F) and if too warm either use a lower wattage bulb or move the bulb farther away from the basking area to get it in that range.
To me a 100-watt bulb in a 12 gallon tank sounds too strong, especially if it's a spot bulb. Again, you need to check the temp. Put a thermometer on the basking area (placing the thermometer on an object the height of your turtle would be more accurate) and leave it there for about 20 minutes before checking it.
A regular lightbulb for warmth works just as well and is cheaper. Your turtle also needs a UVB light.
