921 LED Bulb - T10 Wedge base

921 light bulbs (incandescent) are the most popular bulbs being replaced with 921 LED bulbs.

  921 LED Bulbs

RV dome lights or ceiling lights generally use a 921 LED bulb with side orientation.

Reading lights, wall sconces, and outside lights* may use either a back pin orientation or a 921 LED bulb ("tower" style) which has a 360° viewing angle. We offer a large variety to allow for the best fit for your fixture.

You can use the lumens from the chart above to guide you. For example, if you are replacing an 921 bulb, the chart above shows the average output of an 921 is 119 lumens. Each LED bulb below lists the lumens under Bulb Options. Do you want the same brightness, brighter or not as bright?

Also, please note that some of the LED bulbs are built for sideways insertion, others are for vertical insertion (depending on the orientation of the socket in your fixture), and some project light in almost all directions.

*If using outside, must be in water tight fixture.  DC voltage applications only (not for AC Voltage such as AC landscape lights).
