4. Use floor mats in spots where people step on hardwood directly after being outside. In addition to protecting against wet or muddy footprints, floor mats will help collect any sharp or abrasive materials stuck in treads of shoes. This step will help prevent accidental scraping or scratching.

5. Use felt pads when moving furniture. Or better yet, lift furniture off ground instead of sliding it across your hardwood floor. If felt pads must be used, please make sure that they are free of any debris. Even if a tiny little object like a staple is under that pad when heavy furniture is set upon it, your floor could receive some serious gouges.

These steps will help ensure that your home retains its value by protecting your hardwood floors against major damage.

Accidents do happen, however, no matter how careful you are. If your floor becomes damaged, contact manufacturer or installer for advice.

Thomas Edison Enters Light Bulb Scene

Finally Thomas Edison, after thousands of experiments, in 1879 figures out that carbonized paper filament produces a lasting light bulb. Thomas Edison's bulb produced light for almost 15 hours. Thus, he is credited with producing first effective and useful incandescent bulb.

Thomas Edison tried more than 6,000 different plant species before he discovered one that would work as a proper filament. A few years later a gentleman named Lewis Latimer patented a process that allowed carbon filaments to be manufactured more efficiently. His process extended life of Edison's carbon filaments, producing an even longer lasting light bulb.

Thomas Edison of course never stopped working on light bulb. After creating first incandescent light bulb to last, he worked on creating first useful incandescent lamp. Thankfully many other researchers continued to refine Edison's work. Because of this, there are many different varieties of bulb available today.

Let's take a peak at some of inventions that followed first incandescent bulb.

New Discoveries in Incandescence

The journey of light bulb did not stop with Edison. In early 1900s researchers discovered that tungsten filaments were more efficient for producing long lasting light that carbon ones. Now tungsten is standard for light bulb filaments, even in modern times.

Today light bulb has evolved into a work of art. There are many different categories of light bulb today, aside from traditional incandescent. Some of more popular varieties include:

• Full spectrum light bulbs
• Automotive LED bulbs
• Compact fluorescent light bulbs
• Halogen light bulbs
• Projector light bulbs
• Tanning bed bulbs
• Specialty light bulbs

As you can see, light bulb has come a long way. Thanks to hard efforts of many scientists, light bulb has evolved into a complex creation!
