LEDs Mag had a product article on these interesting little PAR16 LED lamps - They’re three 1W high power LED sources - these are supposed to be direct replacements for incandescent medium screw (that’s E26 Edison for you geeks out there, represent) base R lamps.  Looks pretty cool - these are 20° beam spread.

Check out the article.  Here’s the LEDtronics product site.
