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).
In computers, the term environment when unqualified usually refers to the combination of hardware and software in a computer . In this usage, the term platform is a synonym. We often tend to think of environment as short for operating system environment , but, with the exception of UNIX -based operating systems, the operating system usually implies an underlying hardware microprocessor that the operating system is designed to run on.
