LED Light Bulb Purchasing Considerations
So what should you know when buying LED bulbs? The following list provides some basic guidelines: 1. While the initial cost per bulb remains high, the total lifetime cost of an LED light or bulb is actually lower than that of equivalent incandescent and CFL bulbs. Taking into account energy costs, as well as the time and resources needed to replace incandescent and CFL bulbs, an LED bulb that lasts 80,000 hours has a much lower cost of living. 2. The LEDs are diverse and, since unfortunate shoppers are very likely to find out the hard way, many types are useless for general lighting applications. The best-LED chips emit light with a color rendering index (CRI) of 85%. The CRI, by the way, is a quantitative measure of the ability of a light source to faithfully reproduce the colors of various objects compared to an ideal or natural light source. LED bulbs that use high-quality LEDs will last much longer than the novelty bulbs that many sells and 60% longer than many competitive bulb
