Isn't 32 ANSI流明亮度 very low?

I watched a video a customer took, and it is an interesting device,small, light in weight, yet it does a good job, but in a dark room only.

I have an idea in how to use this device, inspired by that video: if you are tired to watch movie or youtube by holding an ipad, you can hook this small projector to ipad and project the movie onto your ceiling. Then you lay down in bed, turn off lights, start enjoying the movie (until falling in sleep...). The only thing else you need is a stand which can hold the projector vertically.

四百瓦的怎么可能是LED？这种小型／微型投影机只能做做报告啥的，看电影无论从对比度亮度分辨率都不够

400 Watts Projector Lamp is OK for home . ANSI is measured after 3 minutes, how much the brightness drops will depend on the construction of the light, i.e. how good the cooling of the led is. LEDs are x % brighter than other ones but with ANSI we see lower values in specifications.

I think they mean 400W equivalent.
