Three-Pack UV-C LED Replacement

This three-pack supplies three 5 W UV-C LED bulbs built for air purifier maintenance. Each unit uses a G23 base and an arbitrary lamp shape measuring 5.71 x 5.71 x 1.77 inches. The set is intended for households that run compatible purifiers continuously and want spares on hand. Buyers who need a different base type or higher wattage should look elsewhere.

Sustained Output and Service Life

The bulbs are rated for 1012 months of operation before replacement is advised, giving a clear schedule for sustained germicidal performance. Glass and plastic construction resists breakage during routine handling and long-term installation. Stable output is maintained across the service interval when used in matched purifier models. Units operated beyond the recommended period may lose effectiveness.

G23 Base Compatibility Limits

The G23 base and 4.13 x 1 inch bulb dimensions restrict fitment to purifiers designed for that exact socket and envelope. Compatibility is confirmed for GermGuardian models including AC4300BPTCA, AC4825, AC4850, AC4850PT, AC4900, AC4900CA, AC5300B, AC5350B and AC5350. Purifiers with other base types or smaller chambers will not accept these lamps. No adapter or modification is mentioned.

Questions about this item

How much heat does the 5 W UV-C LED produce during continuous all-day operation?

At 5 watts the bulb emits very little heat, so it stays cool enough for constant use inside an air purifier without raising the unit's internal temperature.

Which base and dimensions does the LB4000 need to fit my purifier?

The bulb uses a G23 base and measures 4.13 by 1 inches, matching the socket and space requirements of the listed GermGuardian models.

Will this 5 W UV-C LED work in an older GermGuardian AC4825 that originally used a mercury UV lamp?

Yes, the LB4000 is listed as compatible with the AC4825 and other models, so it replaces the original lamp directly in that older unit.
