Durable and shock-resistant Starts up instantly, unlike CFL bulbs Stays cool and does not give off much heat Frequent cycling on/off will not shorten lifespan (unlike CFLs) Benefits of LED Light bulbs: LED light bulbs will eventually be what we use to replace CFL and incandescent bulbs. Recent developments in LED technology have been 'clustered' to provide more light, and mounted within diffuser lenses which spread the light across a wider area. And advancements in manufacturing technology have driven the prices down to a level where LED bulbs are more cost-effective than incandescent bulbs. This trend is continuing, with LED bulbs being designed for more applications while the prices are going down over time. The following comparison charts illustrate the value of the latest LED bulb when compared with CFL and incandescent bulb for overall efficiency as well as cost-effectiveness.
