Lumen 200 Watt Bulb for Prior Scientific Lumen Systems. Part number: LM200B1-A
The bulb’s lifespan of 2000 hours, compared with a mere 200 hours for a conventional HBO bulb, means less bulb changes, less inconvenience and lower running costs. The light produced by the Lumen 200 is similar in output, but superior in quality; Intensity
peaks with a larger bandwidth improve excitation and overall light brightness is greater.
