LASER/LEDS

[**DONOTDELETE**]

Has Anyone experimented with collimating a bright LED to produce a laser-like effect? What are the limitations to this?

I have tried this, very disappointing results.
The beam is good enough for pointing things, but nothing like a laser.

Probably need something the size of a 5-6D maglite, and use a 5w Luxeon-Star in the back, running of lithium 123's- then use telescope parts inside the other 80% of the tube to focus it properly. Then you can cut your lawn with it.
