Edison light bulbs are reproduction bulbs which are made to look like the the first light bulbs introduced by Thomas Edison over 100 years ago. They are incandescent bulbs with filaments and lens (Glass) which are shaped like the original Edison bulbs. LED Edison bulbs are also shaped like the original bulbs but the filament inside the bulbs are a thin line of LED strip. The LED can be made to produce yellow warm color like the Original Edison bulb or a cooler white color like the newer incandescent bulbs. The advantage of using LED Edison Bulbs is the fact that they last 5 times longer than the incandescent bulbs and use a fraction of the electricity the Original bulbs use. The LED technology used in those bulbs are fairly new (about 2 years). We can expect major improvement in the look and efficiency of those Edison LED in the near future.
