Building an artificial sun that looks unbelievably realistic - DIY Perks

@gargron i just feel weird hearing about a water cooled 500w led going through a blue filter. so much energy. well i guess it must heat the room pretty well

At least from the thumbnail, that's made with an LCD backlight. This is made with a satellite dish.

I wonder how well one of those 500W LEDs could work as a flashlight.
