This period of time is called the restrike time. Restrike times for traditional probe-start MH lamps can take 15 minutes or longer, but restrike times for pulse-start MH lamps are generally much shorter (see Figure 4). According to manufacturers' literature, restrike times for pulse-start MH lamps can be more than twice as fast as for probe-start MH lamps.
Overview. Unix (officially UNIX) is a registered trademark of The Open Group that refers to a family of computer operating systems and tools conforming to The Open Group Base Specification, Issue 7 (also known as POSIX.1-2008 or IEEE Std 1003.1 - 2008).
Operating systems that behave like Unix systems and provide similar utilities, but do not conform to Unix specification or are not licensed by The Open Group, are commonly known as Unix-like systems. These include a wide variety of Linux distributions (e.g., Red Hat Enterprise Linux, Ubuntu, and CentOS) and several descendants of the Berkeley Software Distribution operating system (e.g., FreeBSD, OpenBSD, and NetBSD).
