There is only one brightness bulb for your tv. You have the main bulbs which run the color for the Tv and then you have another bulb which runs the brighness. Typically it is a flourecent bulb inside which does need replacement now and then. Check tje specks on the tv's web site and you should be able to get the model number of the bulb from them and you should be able to purchase it from a repair shop or from online
