4' LED Shop Lights In Costco?
I have no way to check this from down here but it's worth a shot. Reasonable value?

Mex,
From what I have been able to tell with the non relampable "shoplights" is they are using nothing more than LED "strips".
The strips are glued/stuck to the shoplight body which would be the top of the fixture. IF the fixture is made of steel or aluminum then the fixture it's self is going to act like one huge heatsink.. If body is plastic then most likely the strips themselves are self heatsinking (LEDs mounted to a flexible copper coated plastic backer or rigid copper coated circuit board).
The question comes down to exactly HOW the LEDs are driven?
Do they use a constant current power supply as a regulator, a resistor to limit current or my favorite which is typical of most, NOTHING but the LED string(s) to regulate the current which typically results in the lowest cost with the lowest life (after all the non relampable fixtures are designed and built for those not wanting to pay much upfront..
Most of the non relampable fixtures will already have a diffuser already installed which will already be accounted for in the light output ratings and the fixture typically is well sealed to prevent folks from being able to touch any live electrical contacts.
Now if you were talking about something like a retrofit LED tube, the ones I have, use a all aluminum back for a heatsink and are designed to be installed in open or closed fixtures.. No need for added ventilation or fans.
