What are Philips Rough Service Light Bulbs?

When you see a Philips bulb called a Tough Bulb or a Rough Service bulb they mean pretty much what it sounds like. These bulbs are manufacturered with a filament that will withstand constant vibrations and extreme shock.

For example, a customer recently called having trouble keeping a light bulb in his garage door. They all seemed to burn out prematurely. The solution is to use a rough service bulb. It will withstand the constation motion that comes with the opening and closing of garage doors.

These bulbs are also great for portable lighting, like a work light, or near any kind of vibrating or heavy machinery.
