This is not a warming bulb and does nothing to help keep the popcorn warm. A bulb is needed like what is shown in the popcorn machine picture, not these. They are useless in a popcorn machine.
Thank you for your review, Shae! Due to regulatory changes, the replacement bulb for your popcorn machine is now this bulb, which is an LED configuration. This makes it more cost-effective to operate, but does not generate the heat of an old-style incandescent bulb.
