Compared to the LED bulbs of only a few years ago, modern-day versions are simpler and assembled via more automated methods. Leland Teschler, Executive Editor If you tore down an LED bulb manufactured a few years ago you’d likely find evidence of hand soldering a bit of kludgy design practices. We found both these practices in evidence when we examined LED bulbs back in … [Read More...]
