This T4 bulb fits our 12 watt table top magnifying lamps but does NOT fit ALL T4 lamps.
T4 bulbs have a fluorescent tube diameter of 4/8 inches, but they are made in many ring diameters.
If you need a replacement T4 bulb to fit a different lamp, measure your old bulb or lamp to make sure this bulb will fit. (see dimensions).
