Linear LED fixture clearance

[nizak]

I am looking to install some high Bay linear LED fixtures.

They will be chain suspended from eye hooks. Ceiling surface is barn steel.

No where in the install instructions for the fixture does it indicate a minimum distance that the top of the fixture needs to be from the ceiling.

There are louvers along the side of the fixture( fixture depth is 4") that I am assuming are for heat dissipation.

For some reason I have 6" stuck in my head as a clearance dimension.

Tech support is only open M/F, wanted to hang them tomorrow.

Thanks

I think you're thinking of 300.4(E). Here's a quick thread with a similar issue: http://forums.mikeholt.com/showthread.php?t=143811

I wanted to add, as I did not answer one of your original questions, is that the lighting manufacturer will typically not tell you any clearances as it's typically not an issue.

whats the fixture wattage? you should worry more about ambient temperature at the height of fixture during the daytime in summer
