LEDs - Do the Benefits Outweigh the Cost?

Posted by Cliff on from the assessing-the-risks-versus-the-rewards dept.

7x7 asks: "We keep hearing about the latest and greatest thing to come out of LED technology, and every article seems to give an over-view of the topic. How LEDs consume little electricity and last a long time, etc. However the manufacturing process involves super hot ovens and expensive componants. Do the requirements necessary in the manufacture LEDs and LED componants out-weight the requirements for standard bulbs over 10 years? One LED light can last ten years, but contains dozens of LEDs. Has anyone seen or performed an evalutation to see if the trade-off is really anything to speak of?"

  1. only from flashlights by zogger · · Score: 5, Interesting

    --I am an extreme flashlight fiend, I mean I got dozens of them. My LED flashlights are just a sheer joy. The bulbs don't burn out or pop in temp extremes, I got literally years of normal use off a set of batteries. Most of them will run for days if you just turn them on and leave them on, I've tried it. a regular flashlight lasts a couple of hours max usually. I took one of my first ones, a ccrane model, and read several books at night on one set of batts, just to see how they did "real world". Just outstanding.

    I switched several years ago from 12 vdc incandescents to fluorescents for my interior lighting in my RV I live in,got a good boost in performance, but as soon as the LEDs get a scosh cheaper in a normal 12 vdc config for area lighting I will switch to them instead.
