With that being said, do you think the HT3550 will make up for lower brightness with it being superior in pretty much every other way(I know, kind of rhetorical, but still)?
Sage did a thorough investigation of this topic and reported his findings here
That post includes tons of side by side screen captures.
Yes the 2050 is slightly brighter in terms of raw power, but sage notes the HT3550 can go darker which actually gives it better contrast, and contrast rules.
Trying to quantify the brightness difference is a little difficult, but my understanding is the human visual perception of the difference between a 2200 lumen projector and a 2000 lumen projector is not a simple 10% but more like only 5%. But those are manufacturer-reported numbers and really only apply to that crazy green "bright" mode that no one uses.
In calibrated modes, you might see a greater *proportional* difference in lumens, say 20% arithmetically / 10% perceptually.
Kraine has done a lot of testing on just the HT3550. You don't need to speak French to be able to get the gist of the second table (disregard the first table) full of data shown here .
Example: he calculates 1345 lumens in Cinema mode at standard lamp power.
Unfortunately you can't really compare the "lumens" from one review to another. There are just too many variables. So it's not helpful to note that referencehometheater
says the HT2050 runs at about 1655 lumens in cinema mode and projectorcentral
says the "brightest" cinema mode on the HT2050 is 1688. (Strangely they also noted the "preset" cinema mode only gives 1255 lumens at full power which makes you really wonder what their methodology is that can give 400 more lumens in the same mode while still being "very balanced for good video" whatever that means).
Lumens can't be directly measured, and calculating them is as much an art as a science. None of these three reviewers is using the same method and you can't really compare.
So until we get someone who actually *measured* the light output of a HT2050 and HT3550 in the same testing environment, sage's screen shots and personal observations are the best we have to go by.
tldr : HT2050 is technically brighter, but HT3550 gives the better picture in every meaningful way.
