You should watch the episode of mythbusters where they try to build a death ray with mirrors and need a focal point, they make a mirrior in a contact sorta shape and the light focases on it. if you could make a solar cell like that maybe it would work. The episode was on all weekend, it might be helpful for some other things too!

What a dope, actually this already exists.  It’s called the Focal Light Projector; also more subclassfactions of this marvel is Particle Light Projector, and the Vaporizer Particle Projector.

You actually need to buy a fiber optic patch cord, not a cable because the patch cord is going to have adequate protection for a single strand of fiber whereas a cable does not protect individual strands, even though you can pull one of the strands out of the jacket.\nYou definitely need a MULTIMODE cable, especially the older variety - 62.5/125 micron. You can even get lucky and find even more rarely found oldest of them all - 100/150 mkm but the connector is not going to be SC in this case. It is hard to aim a flashlight at a 62.5 light-transferring region so the larger the core the better. You will have no light at all with singlemode cables and very little light with 50/125 mkm, so be careful.\n\nAs to where to buy the cable, the first place I'd look is eBay. Fiber optic industry has suffered a huge setback in early 2001-2002 and tons of materials are still available at dirt cheap prices, especially at liquidation stores and eBay. Good luck hunting.\n\nOh, yes, I think it's worth mentioning that you will have much more luck transmitting light from laser pointer than that of a regular flashlight. See if you application can tolerate red light and if yes then definitely go for a laser pointer.

I'm almost positive it was a flashlight also.

There are a number of products on the market that will do what you want, and be certified and safe.\n\nMake sure you get a warm LED though: cool white LEDs produce a terrible colour of light.\n\nhttp://www.theledlight.com/120-VAC-LEDbulbs.html

I googled courses "lighting technician" and got about a thousand hits, including colleges.  There would be a lot of info there.

It's my opinion that the light is a gimmick.\nThink about it this way... a dentist has to go through tons of training to be able to offer his services... why (and how could) someone just start selling some of that stuff to people... especially something like a "laser?"\nIt is just a gimmick to make a little more money... \nJust my opinion

Any light that is bright enough can be seen in "broad daylight" - so the tail lights of the car in front of you at a stoplight are visible, right?\n\nNow, for the sake of reference, laser light is generally the "brightest" source of light in terms of watts per sq cm, so all comparisons of brightness should be done with that in mind.\n\nOC

Interesting thought.\n\nThe first answer is right for leaving a point source, I would think. Most flashlights have a source and a parabolic mirror. Light from the focus of a parabola reflected off the surface will come out in parallel beams.\n\nLet's change your question to a flashlight giving out a nearly instantaneous pulse of light. I think we would see 2 pulses coming out of the light. The first would be a spherical shell from the light coming out directly, without reflecting off the parabola. Following that would be another pulse from the reflected light. I believe this would be slightly concave, since the path followed by the light towards the middle would have a slightly longer path to follow. \n\nThis is making a few simplifying assumptions, such as a point source for light and a perfect parabola. I would imagine in reality the distributed nature of the lightbulb would make for an irregular shape.
