Regarding fire risk, keep in mind if you or someone in the future installs the wrong light bulb in the fixture than what it is intended/labeled for (i.e. non LED instead of LED, or higher wattage than the fixture is rated for - even LED). Construction and labeling between these two fixtures are not the same, I suspect. Side note: even though LED is lower wattage it might get hot from a fixture testing standpoint so be sure to go with rated wattage per fixture manufacturer regardless.
