They are not nearly enough to be worrying about overheating the can.

Q: If I do use boxes pre-built or I-built, would you just build 4 sides an=

four sides. leave the top open. make sure the sides are high enough
if you have blown insulation.
Scott: My concern is that if cold attic air was able to be in contact with the ceiling around the light, it could cool the ceiling to the point that it could start to sweat (condensate and drip)
It was gfre.. that mentioned that prefabbed boxes were available for this purpose.
Dean: That's a little overkill, might work. probably not deep enough.
Looks like people are building there own boxes:

Found some pre-fab units, Kinda expensive ...

What would a 2 1/2 gallon gas can cost? Would a 1 gallon be deep enough?
Full or empty?

I was thinking he could cut the bottom out then set the can over the light. Take the
cap off for ventilation. Spray paint it green to be environmentally correct.

That looks like a winner

The key to these things is you just need to know what the thing you're looking for
is called. Once you know that you know what to search for. I just went through that
with my gas grill renovation. I need two little widgets that go on after the two big
wheels to hold them on. I've seen them many times, never knew what they were
called. They are the washer kind of thing, with teeth on the inside, where you push
it over a rod or shaft and then spring tension keeps it there. I had no idea what they
are called. Turns out it's called a push on lock star washer or fastener. Now I just
have to hope that Lowes has it, already tried HD. HD has greatly reduced their section
where they have things like this in drawers. Lowes has more, but many times
when you find the drawer, most of it is empty, the rest is all jumbled up, all kinds
of wrong sizes, wrong widgets, mixed in. I'd gladly pay more for this stuff if they
used the money to hire a part time kid to keep it stocked and orderly.

I would go to Ace Hardware for that. They are locally owned and far
more responsive to the needs of local people. I would get a guy or
lady who knew exactly what I wanted and walk me over to it, maybe even
giving me tips on how to install them.
Sometimes you have to admit, paying an extra nickel for a widget is
worth it to get a little service. Ace is always my first stop for any
kind of hardware item, even if I could find it myself a little cheaper
at the BORG.

Fact: I was sitting on the floor at the Home Depot once reorganizing
several boxes of missorted FMC connectors trying to get the ones I
needed and an employee who knew me actually walked by and said
"That's why we call this a 'do it yourself' store. If you want to find
something do it yourself".
He kept walking.
