Durata lampada Z2 e Panny 500
questo commerciante americano invita a non farsi troppe illusioni su quanto dichiarato dalle case sulla durata della lampada:
Lamp life Panasonic no longer makes claim of hour improvements in low lamp mode. The AI settings will extend the lamp life...however...anyone who anticipated 5000 hours on the 300 were kidding themselves. The lamp will deliver near out of the carton performance for about 2000 hours in low lamp mode... and will quickly diminish to replacement at about 3000 hours. I'm not saying this.. the Panasonic engineers are saying this. High lamp setting will require a lamp change @ 2000k hours.
Our own practical experience on lamps... Sanyo lamps tend to perform at acceptable levels much less than other manufacturers. We carry and sell EIKI projectors ( all Sanyo OEM) and they tend to perform well for about 1000 hours across the board.. and then they drop quickly after that.
