Wall mount used as Ceiling light fixture

I just bought a wall mount light fixture which a label inside states that it is for wall mount purpose only but I had the intension to use it as a ceiling fixture. I contacted the company and the tech. was not sure why this is except that it was only tested by UL for that purpose. Is there any reason why I couldn’t/shouldn’t use it on the ceiling?

You might not like looking at the exposed light bulb at one end of a wall sconce.
I believe the mounting flange on a ceiling mount is insulated to dampen the heat from the bulb, but you better get some advise from an electrician

Now that you mention it they did say something about heat on the ceiling but did not elaborate. I apprecite the info. and will get a proper ceiling mount.
Thanks again.
Heat dissipation from a vertical surface (wall mount) is much diffirent and much better than heat dissipation from a horizontal surface above (ceiling mount). The manufacturer/UL may only have tested it on a vertical surface, it may have passed by a wide margin and MIGHT be okay on a ceiling. But sight-unseen, shoot-from-the-hip, SWAG by someone who listened pretty carefully during those upper-division course on heat transfer (me): If the wall-mount is rated for 100-watts, that would equate to maybe 40 watts in a ceiling-mount. If the wall-mount is 60-watts then a similar reduction doesn't leave much wattage for the actual illumination task at hand.
