Need help finding wide angle LED\'s

HI I was hoping someone might know where to find LED's with viewing angles in the 45 degree and up range.I did find some but they were kinda expensive at $2.00 each.Thanks for any help.

You can cut off the head of a regular LED to get near 180 degree angle. To do so, simply use a thin blade to cut ~1mm above the LED die, then use fine sandpaper, followed by toothpaste to polish the end.

I used that method to make homemade "lasers" in the early 1980s. Granted, they weren't very powerful, but I could project a beam across a large, moderately-lit room and get an easily visible spot on the wall.

Look for "spider" LEDs or rectangular 120/140-degree LEDs. They both cover very wide angles.

www.whitelightled.com sells white 120/140 LEDs. $1 each, and I think they're Nichia product - good fellow to deal with even if his site is a bit crude.
