UV-C bulb set for GermGuardian purifiers

This pack supplies four 5 W UV-C lamps with G23 two-pin bases, built to fit the listed GermGuardian air purifiers. The tubular bulbs emit white-tone UV light at a CRI of 80 and are rated for roughly twelve months of continuous use. They replace the original LB4000 modules without rewiring.

G23 base and 5 W limit define fit

Each lamp draws 5 watts and uses the industry-standard G23 bi-pin base, so it only works in sockets designed for that exact format and power level. The physical envelope measures 5.51 by 5.51 by 1.97 inches, matching the factory dimensions. Purifiers requiring a different base, wattage or envelope will not accept these bulbs.

Twelve-month rated life decides replacement cycle

The manufacturer specifies an average life of twelve months and recommends changing bulbs every ten to twelve months for best germicidal output. After that period UV-C intensity drops below the level needed for effective VOC reduction and allergen control. Buyers who need longer intervals between changes should look for a different bulb technology.

Questions about this item

How do I decide between the four-pack and a single bulb?

The listing is a four-pack only; each bulb is a 5 W G23 UV-C replacement rated for 10-12 months, so one pack covers a full year of changes.

What does the 5 W rating mean when the bulb is running in my air purifier?

It draws 5 watts of electrical power while producing UV-C output for germ reduction; the lamp tone is white with a CRI of 80.

Will the G23 base fit the socket in my GermGuardian unit?

Yes — the bulbs use a G23 two-pin base designed for the LB4000 slot found in the listed compatible models.
