I hated the weak 40w incandescents that were in our rangetop microwave. They barely lit up the stove with a very yellow light that made all food look. bad. These were a GREAT upgrade to that. I bought two and installed them, immediately everything was much brighter and in pure white light. I was a bit concerned about temperature increases with these, measured with my IR gun these get on average 20° warmer then the incandescents I had previously. However it seems to be within tolerances, it doesn't seem to present any hazard. My manual doesn't state any specifics on replacements or specifications for bulbs except "Max 40w". It also has a high/low setting and these dim just fine with it. The only other thing I had to do was get bulb adapters to go from E12 (these) to E17 (what my microwave range socket took).
