The heat from cooking added to the heat from the LED electronics bulb will probably shorten the bulb life somewhat. But unless you have a very strange cooking arrangement, the temperatures around the bulb aren't going to get all that hot for all that long. And, if the bulb is not on all that much, you probably won't notice the shortened life from maybe 24,000 hours down to maybe 5000 hours. Live it up and try it, 40W and 60W LED bulbs are down to $1.97 at our local Menards and Home Depot stores.
