It's a great idea to keep a spare lamp for TV. You never know when yours decides to go on the blink. For stockists of spares for television sets also you would be glad to know that Projector Lamps World are the leading distributors of replacement bulbs and lamps for both the multimedia projectors and the rear projection TV sets throughout the world. The TV projection lamp could be for popular brands as well as brands that are not known so well.
You can pick up a TV projection lamp for Akai or Hitachi as easily as you would one for the Barco or Christie, Clarity or Dwin and Electrohome or Evevis. When you want a lamp for TV even if you do not have the part number it would be adequate if you mentioned the brand and the model of the set. It is economically more viable to buy the lamp instead of ordering the complete replacement kit.
