Beware, 200 Lumens is very low. Fun if you can make the room completely dark. Stuff like this "3 times higher resolution than most 480P projectors" also makes me scratch my head. 1080p is 6.75 x the resolution of 480p, what the heck are they talking about. 1080p is also 2 million dots, not 20 million. Dodgy.

I see what you mean, but its using something called ansi lumes wich seems to be a diferent mesurement. Dont know if 200 is good with that messurement.

But im not worried. I work at night, so Im already prepared for  that and have full black out room. Living room is mostly blacked out but is an easy done.

ANSI lumens just means they used a standardized method to measure the light output. There is no conversion going on. ANSI lumens sounds more reliable in marketing. However you can trust ProjectorCentral. They provide a throw distance calculator which will tell you the end result what to expect in terms of brightness for any screen size and type of screen. It will also show how much ambient light you can have for the screen size you are aiming for.

In the dark it will work, just expect a dull image more suitable for 65" projection. For example a 250 lumen pocket projector

Max screen size is 75" for a 15 fL (50 nits) image brightness, that's on a screen. Below that they recommend a brighter projector. So for 200 lumens you want a smaller screen.

LED projectors generally do provide a brighter end result than LCD. My projector is rated at 1100 lumens, yet comes up with 15 fL at 102", 28 fL at 75", not even double for 4.4 times brighter lamp. Lumens is not the end all measurement hence why projectorcentral is so useful. FYI halving the screen diagonal size, quadruples the image brightness and vice versa.
