Lumen is a simple way to indicate the amount of light the projector has to produce the brightness of the picture. The higher the number the brighter the picture.
Image brightness from a projector is normally measured in ANSI lumens. Lumens is a brightness measurement and ANSI lumens is a method of standard brightness measurements for projected images. The measurement is based on certain video levels and patterns and helps to compare the outputs from different projectors. Most manufacturers now quote an ANSI lumen figure although some choose to quote a lumen level that may not be based on the ANSI measurement system. The non ANSI levels will generally be a rather higher figure so they do not offer a comparison with industry standard measurements. Apparent brightness is also dependent on the ambient light falling on the screen as well as the contrast range of the image itself. For these reasons, don't let the brightness rating influence a choice of model without taking other factors into account.

No it doesn't have to be dark.. Bt if it is dark. And it would be u can see clearly. Most home cinema systems have high lumen lamps for use in daylight conditions. How bright the image appears will depend upon the strength of the projection lamp, the distance from the wall, the brightness of the room and the material projected on to. For indoor household daytime use, a 2000+ ANSI lumens projector will be needed. To get the best image, use a projection screen or reflective wall paint such as those offered by Goo Systems.

The 30000 ANSI lumens
It refers to the brightness of a projector, with 800 ANSI lumens representing the amount of light output it can produce. A higher lumen count generally means a brighter image.
Both are unit of brightnes and usually shows numerical value of brightness in projector. lumen is measering unit of each pixel which generates by light source .it tallest brightness away from centre and other mansion is equally distributed cause of generated by led .
One lumen makes up 1 ANSI lumen as they both measure the same output of light. ANSI lumens are used exclusively for measuring the output of projectors.

Some of the main features for the Panasonic PT-DZ6710U DLP projector are it's brightness rating of 6000 ANSI, a contrast rating of 2000:1 and the compatibility with all input formats ranging van SD to 1080P / 60Hz HD signals.

The power consumption of an basic model of LCD projector is around 250W to 400W depending on the make and model, brightness 2000 to 3000 ansi lumens SVGA projector.
It's #150.
np40 is equivelant to ansi 300#
