    How about a cooler located in Sahara Desert?

    there are several mfgs of 4 ft or 8ft 2 lamp t-8 IP 66 luminares, most are poly carbonate and easy to install. I have seen them at the big box stores. jelly jar luminare with 100 W inc will be about 900 lumens, not very much light

    Inside freezer is not an issue with moisture but any penetration to outside freezer walls may be an issue with moisture. I've seen switch boxes full of ice

    Exactly. Yes.

    See 300.7(A). In the case of a small walk in freezer, the opening and closing of the door will act as a bellows, to a degree, and exacerbate the movement of air in any raceway that penetrates the insulated enclosure of the freezer.

    I use 4' LED vaportite fixtures; typically I'll have one penetration coming though the ceiling panel and either EMT for long runs or NMLFC for short loops between them.

    Make sure conduits entering a refrigerator, or freezer are sealed or you will be back. Duct seal works fine.

    Fluorescent is bad news for this. Normal T8 might never get to working temp in a freezer. This is where LED works well. Vapor tight or something designed for refrigeration is ideal.
