The Arista UV Light Source Replacement Bulb is a 36 inch F-30 T-8 bulb that runs at a peak wavelength of 370nm. It is for replacing lamps in the UV EXPOSURE SECTION of the Arista UV Light Source 30x36. HIGH OUTPUT (HO) replacement bulbs (item #263036900), like the bulbs originally installed in the Arista UV Light Source, are also available.
If exposure consistency is problematic, it is recommended to install an entire set of 8 bulbs, when a bulb burns out or their strength begins to diminish.
For replacing the LIGHT TABLE (TOP) bulbs, please see item #2630365.
