http://led.linear1.org LEDs explained--bringing you solid state light Copyright 2006 Fri, 08 May 2009 15:46:47 +0000 http://wordpress.org/?v=1.2.2 http://led.linear1.org/led-mag-lite-now-available/ http://led.linear1.org/led-mag-lite-now-available/#comments Wed, 20 Sep 2006 18:48:13 +0000 LED products http://led.linear1.org/led-mag-lite-now-available/ Today while shopping I noticed a 2D Mag-Lite with a 3W LED instead of an incandescent lamp. This is an OEM LED, not a retrofit. I bought it at Wal Mart for $33.28 (roughly double the price of a 2D Mag-Lite). I'll update this post with pics shortly. but it ... http://led.linear1.org/led-mag-lite-now-available/feed/ http://led.linear1.org/hello-make-readers/ http://led.linear1.org/hello-make-readers/#comments Tue, 03 Jan 2006 21:58:19 +0000 Practical LEDs http://led.linear1.org/hello-make-readers/ Hello and welcome to all the readers of MAKE: blog, who kindly wrote up my site today.
