E26 12V Led Bulb 4W Cool White 6000K AC 12V/ DC 12-24V Low Voltage for Rv Camper Bulbs Off-Grid Solar Battery Systems Edison 40W Equivalent (2 Pack)

I searched online, and there are results for a 4watt LED E26 24V bulb. If those don't match, then I suggest looking at a bulb you already have, finding a model number or any useful information on it, then searching based on that. Maybe do so and respond with a picture of that and what the bulb looks like. The 24V requirement is pretty odd, but the bulb I sent claims 12-24V while meeting everything else..
