Tungsram is one of the most well known bulb companies in the world. They have been making bulbs for household and commercial use for over a hundred years, and have never stopped being innovative. They take a lot of pride in their products, and they have been known to be a little bit more expensive than other brands because they put more emphasis on quality and safety. Tungsram's light bulbs are made with high quality materials, which can last up to 25 years and never burn out, and they also have a guarantee that they will always come back to you if there is any damage after purchase. The bulbs that Tungsram makes are also some of the most efficient on the market today, which means that there is less heat produced and that you won't need to replace them as often. They are also approved by the U.S. Environmental Protection Agency for safe use in homes and buildings, so you know that the materials used in them are going to be safe for your family, too.
