Light bulb clearances in garage

New construction home had this light fixture and fluorescent bulb installed less than 3" from finished sheetrock in the garage. What are the recommended clearances in this case? Any feedback appreciated.

zero clearance, non issue.

Zero clearance, but common sense. They should not touch a combustible. Look at your code check.

It can and will get hot. I made the mistke of storing some material in the rafters (I have an open ceiling in my garage) near on of my lights. Even at 60 watts it scorched the material and seriously deformed the vinyl siding I had up there near it as well. Common sense says not too close but I havn’t seen any code numbers here in Canada, except for insulation clearances on the other side.
