the lamp i use is a 20W halogen desk light, i'll take some shots to show it, problem comes from the screen, i've painted it with multi coats to get a nice effect (primary paint to give a "base" to paint, + 2 coats of white spray +2 coats of smile black stencil + 2 coats of varnish) all these coats of paint had lowered the transparency of the screen so when the light is on, the effect is very low with that light but at base theses halogen lights makes a high clean power light.

the effect i tried to get was not to get a working high power light, but an ambiant light, and the effect i got on light effect is very weak even to do an ambiant light.

i think about ameliorate effect with using another light inside case but not inside screen, as i have many holes now where was the connectors it will make a light effect wich can be nice.

and for the ones who think it's a bad thing to destroy an old mac and paint it, i can just say that this mac was stored OUTSIDE on rain, bad weather and all, on a top of an pile of old pcs on a iron seller (dunno the right word fir this job (a guy who sold old parts of iron like old cars, olds chairs, old things from army, things like that) (i have to go back there agian becuase there's still one or 2 apple II in this stock i couldn't take the 1st time i go there + some old apple keyboards an parts), if i didn't get it (the 512k) rain had destroy it at all cause no one had buy it + i sold boards on ebay for nothing so they have make some mac collector happy).
