It's no surprise that you've become attached to your Sony VPL-FX51 projector--it lights up large conference rooms like no other, thanks to its outstanding 5,200 ANSI lumens of light provided by the 250-watt UHP bulb. While each lamp lasts an approximate 2,000 hours, it's a good idea to keep a spare on hand, just in case that 2,000th hour arrives in the middle of an important presentation. Sony includes a 90-day warranty.
