Hi everyone, was hoping that you'd be able to shed some light on this for me. How does Epson have the same bulb (250 W UHE ) in multiple projector models ,specifically HC3800 ,HC4010, HC5050ub and all have such widely different Lumen output ie 3000 ,2400,2600. All also have the same lamp hour rating. I know that obviously the optics used will play a factor but the HC3800 is the cheapest and it apparently is the brightest at 3000 lumens . There is a difference in lcd panel size however. The HC3800 lcd panel size is 0.61" vs the other two which have 0.74" lcd panel size. ( a bigger panel size is better right?).
Is there something more that i'm missing ? Is Epson massaging the numbers or something to do with achievable contrast ratio's ?
Any insight in to this would be very helpful .

Isn't it a shame that it takes a quarantine for my wife to appreciate my Home theater set up!
