after reading a number of blog entries on how to fix my sony wega projection tv, i started shopping for the replacement lamp. I found several 'dealers' and amazon.Amazon may not have been the cheapest, (but only by a couple of dollars), but i was confident that what i ordered would be what i'd receive. I was a little concerned on some of the other sites whether the bulb was standalone or in its lamp casing.The lamp arrived ontime, and was easy to install.
