4-Pin Base
This is a Caprock brand lamp that is 100% compatible with OEM lamps selling at much higher prices.  It measures 843mm (about 33.2 inches) excluding the 4 pins on the end of the lamp.  Its peak output is at 254nm.  The rated useful life is 10,000 hours.  Although nominally rated at 39/40 watts, some systems will overdrive the lamp for higher output at the expense of a shorter life.
