I have tried the "tuff bulbs" - they seem to have a stronger filament and don't go dark as readily as the "normal" ones, but are still prone to breaking/shattering as easily as the regular ones.
I had one let go when a drop of cold water fell on the bulb when I was under a vehicle and I got glass in my eye and had to have my wife take me to hospital to get it all out
Now I use nothing but the "safety" style which are covered in a thin film of clear rubber. Even if you smash the bulb, it is all contained in the rubber covering - no flying glass.
These are also a "tuff bulb" and last a LONG time in my drop lights, while making me feel a lot safer - glass in the eyes is NOT a fun thing!
