Choosing Between Them

Choose the SerBion 25 Watt bulbs for their reliable fit in large units, though specialty high wattage lamps require matched power ratings. If you manage multiple small diffusers around your home, the OuuKoo 15-pack suits high volume needs, while standard candle warmers benefit from the flexible twenty-five watt multi-packs.

Remember that using the wrong wattage in a compact or adjustable lamp can lead to uneven melting or overheating. You should always double-check your appliance manual before swapping out replacement hardware.
