LabStrong Replacement for Barnstead LMX13 Higher Power Ballasts


The LabStrong LMP01 is an economical and reliable replacement ultraviolet (UV) lamp comparable to the Thermo Scientific™ Barnstead™ LMX13 UV Lamp. The lamp is effective at germicidal and total organic carbon (TOC) reduction in water through the use of 185 and 254 nanometer (nm) UV wavelengths. The LabStrong 185/254 nm UV Lamp is suitable for operation in the Thermo Scientific Barnstead DIamond™ TII and NANOpure™ DIamond (with new style ballast) water purification systems.

The lamp filament has been design has been sized and tested specifically for matched operation with the higher powered Barnstead TN1403X1 Ballast (3 x 2 x 1.5 inches). The lamp’s quartz glass includes an extended life coating to minimize mercury migration into the quartz. The rated average life of the lamps at six starts per day is approximately 9,000 hours. For maximum product performance, LabStrong recommends replacing the lamp at this time, as the 185/254 UV wavelength output intensity will be diminished. To extend lamp life, LabStrong also recommends limiting the number of times the lamp is started per day to six times per day.
