Lumenivo LB4000 UV-C Replacement Bulb 2-Pack

This twin-pack supplies two 5-watt T4 fluorescent UVC lamps with G23 bases. Each bulb measures 1.25 by 1.25 by 4.25 inches and is rated for 8000 hours of operation. They are designed as direct replacements for specific Germ Guardian air purifiers.

Fits select Germ Guardian models only

Compatible units include AC4300BPTCA, AC4825, AC4850PT and AC4900CA. The lamps emit germicidal UV-C light to inactivate airborne viruses, bacteria and mould spores without producing ozone. Buyers with other air purifier brands or models should look elsewhere because the base and dimensions will not match.

G23 base and 5-watt rating determine fit

The ANSI G23 two-pin base and 5-watt power draw are the critical specifications that decide whether this bulb works in your device. Verify the original bulb carries the same base code and wattage before ordering. EPA Est. No. 97601-IN-1 is listed for the product.
