I just went to the kitchen cabinet to get a lightbulb. I can not believe what happened. You know how bulbs come in those cardboard boxes, holding 2 bulbs, and pretty well padded. I have dropped those things numerous times and never broken a bulb, not even on concrete.
I just knocked down the same sort of package, with 2 ROUGH SERVICE bulbs. It only fell about 4 feet and onto a linoleum (on wood) floor. One of the bulbs literally exploded, the largest piece of remaining glass is probably about 1/4".
Rough Service MY ASS !!!!
The only thing rough about them is the price I had to pay, compared to a standard bulb.
