Hello, this is my first post. I'm thinking about using 100 LEDs each of 1watt and each capable of 70 lumens on average. Which make it a 7000 lumen led configuration.
I've thought about an idea of using these leds in such a way that very minimum light is going to be wasted and all of the light is collected by collimator. I will use a bowl(half sphere) and inside that bowl i'll place the leds perpendicular to the inner surface of the bowl.

each led is 8mm in width.
Is 7000 lumen enough if I have a screen of 8 - 9feet.
i'm using 220mm fresnel
14.1 inch lcd
330mm fresnel
320mm triplet
Thanx in advance
