Used to use one of those lights on a daily basis when I did radio repair work. The only weak link is the hinge points will get weak and break off an ear.
You can redrill them if your careful.
But she probably is not going to put it thru the abuse mine went thru with 2 shifts of repair work per day/ at 6 days a week.
The replacement bulbs I picked up at the local hardware (Ace).
