i googled "reptile light guard" and one of the hits was ebay. there's a bunch on there and a quick scroll, i found this: https://www.ebay.com/itm/Reptile-Amp...YAAOSwR9pbIN2o per the pictures, it's supposed 15cm which is like 5.9inches (but the descriptions below says 5.12cm :/ ) also they do look like minnow traps lol.

i also like the idea a fashioning hardware as Star mentioned. here are some light guard options from Home Depot. u use a screw to tighten them around the neck of the light fixture instead of the base.:

me - i would just go to LLLreptiles, get this overly large guard and call it a day: http://www.lllreptile.com/products/3...ght-cage-cover it's a 6.25inch cube all the away around. they have storefronts in SoCal.
That makes a lot more sense that I was imagining, thanks for the clarification! lmao.

Those last few things Ax mentioned seem like your best bet in this situation. Teamwork!
