MIXJOY Ceramic Heat Emitter 2 Pack 100W

Never used, but the bulbs can be tested in person since I cannot demonstrate they emit heat through the listing. *Must bring housing unit to test* I am selling my units and if in case they sell, I will not have any to demonstrate so please bring. My bearded dragon passed away and never got the chance to use it. Two MIXJOY ceramic heat emitters for reptile terrariums. Each bulb is 100W and rated for 10000 hours of use. These 110V-120V bulbs operate without emitting light.
