"Using lamps that have a reinforced glass shield around the arc tube to absorb the impact of flying arc tube debris, preventing it from shattering the outer bulb. Such lamps are safe to use in 'open' fixtures. These lamps carry an "O" designation on the packaging reflective of American National Standards Institute (ANSI) standards.
Lamps that require an enclosed fixture are rated "/E". Lamps that do not require an enclosed fixture are rated "/O" (for open). Sockets for "/O" rated fixtures are deeper. "/E" rated bulbs flare at the base, preventing them from fully screwing into a "/O" socket. "/O" bulbs are narrow at the base allowing them to fully screw in. "/O" bulbs will also fit in an "/E" fixture."
