This is Turtle.

The Rough service light bulbs are for rough service and not for high
empact use. if you don't drop it. It will out last 3 or 4 regular
bulbs.

Also all rough service light bulbs are not the same. Look at it and see
if it has 130 volt rating and it is a good one. if it has a 120 volt or
a 125 volt rating. they are nothing at all and just trash. Look at the
rating to see if they are any good !
