I have 4' stacked vision cages and after having to change
the basking lamps I modified things a little for easier lamp
maintenance.
I drilled out the pop rivets which hold the grill onto the
bottom of the basking lamp shroud. I removed that circular
grill totally and whenever I now need to change out a basking
lamp it is easily done through the bottom shroud opening.
No more shifting those heavy sand substrate cages around to
get to the lamps from above. If you don't pile a basking site
too high under the shroud the lizards will not be able to reach
it or the lamp.
I was actually going to use the grills but actually attach them
from the bottom side of the shroud opening by using a hinge
on one side and a winged nut machine screw on the opposite
side so that I would simply undo the wing nut and let the grill
drop down for lamp maintenance but haven't found the time.
I think this would be a great suggestion to the Vision Cage
Co so they can begin to produce/modify the riveted grill
with one which can be easily opened downward by undoing
a wing nut or small latch of some type on the opposite side.
Another advantage to not using the grill at all is that the
basking lamps I use in these cages which I've modified are
now less wattage. Hence, energy saving not to mention that
the UVB/A discharged as well as equal heat (from a smaller
lamp) is no longer filtered by the grill so it's a win win
situation.
