These 2.5V mini Christmas replacement bulbs for incandescent string lights are made with a pinched base which means that they will fit most light sets (whether a pinched base is required or not). 2.5V lamps are very common for string lights with 50 or more lamps, however it is very important to confirm the amperes (or wattage) for your particular light set to be sure that you get the correct brightness. We offer the following three options for 2.5 volt lamps:

170 mA (0.42 watt): These are the most common 2.5 volt mini replacement bulbs used now-a-days and are intended for use with incandescent string lights that require 0.42 watt lamps. These lamps will shine nice and bright in light sets that recommend between (0.41 – 0.44 watt lamps).

200 mA (0.50 watt): These 'high wattage' replacement bulbs are for use with incandescent string lights that require 0.5 watt lamps. These string lights are fairly common and have been the standard for certain brands, most notably GKI Bethelem. The 0.5 watt bulbs are intended to be brighter than traditional 0.42 watt lamps, however, if you use these lamps in a light set that requires a lower wattage, they will often glow dim. It is important to double check the wattage (or amperes) required for your light set before purchasing.

100 mA (0.25 watt): These lamps are intended ONLY for incandescent string lights that require low wattage or energy saver light bulbs. This wattage is not common, but it has been used on different light sets and decorations for years. Most light sets of this nature will specifically state that you need to use 100 mA bulbs (or 0.25 watt) bulbs as replacements. This is typical of light sets termed heavy duty and it most commonly found on sets of 200+ lights or icicle light sets. If you use these replacement bulbs in light sets that require higher wattage lamps, these lamps will flash and burn out immediately. It is important to double check the wattage (or amperes) required for your light set before purchasing.

These 2.5 volt replacement bulbs are sold 'naked' which means that they do not come with any plastic husk. Please be sure to keep the plastic husk that the old bulbs are removed from so that these will incorporate into your string light. The unique pinched base shape to these bulbs allows them to set fully down inside of most any husk to make meaningful contact with the brass contacts inside.

Please be sure to reference the tag near the male plug on your light set to confirm both the voltage and the wattage for your string. Voltage, amperes, and wattage must all match to ensure that the lamps will light with proper brightness.
