hello,
i have been doing an art project for a while now where i use a special machine i made to collide two hollow metal boxes together, and film the collision with old 16mm high speed movie cameras, taking movies at 500 - 2,000 frames per second.
i have been lighting an area about 60 x 60cms with three 1000W narrow spot par globes, on separated phases of a 3-phase outlet, so ythat the 50Hz flicker is softened between their three outputs. i film from between 20 - 80cms from the lit objects. when i measure the lux with a crappy lux meter i have, i get a reading of around 60,000 lux at this point - a touch more than the daylight reading with this meter at 45,000 (the meter may be crap, or i am reading it wrong....)
what i want, is to ask if there is feasibly an led alternative using an array of high power leds and lenses, that i could make (i am very handy with lathe and all sorts of stuff....) there is a similar idea here in australia, using what looks to be 100 3w leds???
basically - am i barking in the wind, or is something like this possible to replace the kind of intensity that i have been getting with the three par cans i have? more would be better, of course.... my budget would be around $2000 max for parts, though all the hardware i can make myself.... leds are appealing for the lack of heat in the light (the boxes smoke after a minute under the pars), their flicker-free nature, the significantly less power drain they create, and the softness of an array.
in thanks,
sean.
