I have an epson hc720 and this is the first time ive had to change the lamp. Right at 1600 hours, i get the replace lamp warning and the hours are displayed in yellow. I was still very happy with the brightness and surprised that the warning came on.
I went ahead and changed the bulb, turned on the pj, and got the replace lamp message. Now, while the image is brighter, its not by much and maybe more placebo affect than anything else. Are these projectors automatically set to give a warning at a certain hour mark? To me, the old lamp still had plenty brightness and i feel like i changed it prematurely.
