Questions about this item

Will this 9.5 W UV fluorescent lamp operate in my existing T8 fixture?

The lamp follows the standard T8 form factor, so it fits the same sockets and ballasts as other T8 tubes you may already have installed.

How can I verify the UV output is still effective after installation?

After 4000 hours of rated life the UV intensity drops off, so plan to replace the lamp once you reach that runtime or when fluorescence in your diagnostic or microscopy setup noticeably dims.
