Used in rebuilt light fixture. They should offer the same physical bulb in a higher wattage.

Q & A
Is there an LED or Halogen alternative?


We do not have an LED alternative for this specific bulb.


What is the overall height of this bulb? I'm looking for 15 w bulbs to put into night light type scent warmers, so they have to be small, but must be at least the 15W. Small 4-6W bulbs dont get warm enough to put off the scent...


This item measures 1.97" in length, including the base.
