Are other Philips bulbs the same as their Duramax bulbs?

Philips created a group of light bulbs that are incandescents which have a little different technology and cause them to last a bit longer than your regular incandescent called Duramax Light Bulbs. These are mostly what the big box stores sell of Philips. If you are looking to purchase other bulbs that are the same wattage but just not Duramax or not the same voltage, the color of the light put out will be exactly the same. The only difference may be the life of the bulb and/or the brightness of the bulb. 130 volt bulbs will be slightly less bright but not tremendously.
