I have been playing around with LED (Light Emitting Diodes) for the past week. I made one device using a bright red LED from Radio Shack with 2000 MCDs and one amber which said 12000 MCDs (Which may have been a misprint). I dropped the amber into the shell of a standard flashlight bulb with a resistor and but the "bulb" in a standard 2 Dcell flashlight. There was certainly enough light to read by and as a signaling device, quite bright in the dark. It has been on continuously since last Friday with no change in brightness. Last night I built a device with a radioshack battery case, a small switch and the red LED. It's rated at 2000 MCDs but seems much brighter then the amber, and it's VERY visible at night. I intend to leave it on until it dims or fails. Either of these LED units are bright enough to read with and they certainly have the advantage of being invisible to insects. cu Bob Denton Aqua-Gulf Transport bdenton_at_aquagulf.com www.aquagulf.com <http://www.aquagulf.com> *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Tue Jan 19 1999 - 05:55:15 PST
