Default Led drivers installed in open space or box?

My friend called and asked if it's ok to install these drivers in an open celing. He has 120 line low voltage load. Should these be installed in a 12x12 box or similar or would they get to hot?

Those holes are designed into the cover for a reason. Limiting their ability
to shed heat through convection would very likely result in a corresponding
limit to life expectancy.

They should be in JBs with those exposed 120V terminals. id put a screened hole in top and bottom of JB to allow for cooling though.

Those drivers in the pic are very common on the convention shows.
Just like the T101 timer plastic cover over the screws, these also have an insulating plastic cover over the screws. In both cases most of the time the cover is missing.

They normally have a short cord and cord cap on the 120v side and we plug them in that way for the few day show.

The heat they put off depends on the load. Sometimes they get hot to the touch, like a dimmer with a full load. If they overheat they'll start flashing.

In building construction I would choose a different model that comes in a can with 1/2" knock-outs.
