What is the purpose of a screen saver? Screen savers served both a technical and a marketing purpose. From a technical perspective, the purpose of a screen saver was to keep an image from permanently being engraved in a CRT-based monitor’s phosphors.

I’ve been buying modern forms of light bulbs for almost 15 years now. So when someone asks me, “Are LED light bulbs worth it?” or “Do LED lights really save you money?” I can answer the question. I was more accepting of CFL bulbs than most, but I had some reservations about them. On the other hand, I really like LED bulbs.
