>The easy bake oven uses a filament light bulb as a heating source. They stopped using light bulbs as the heating source more than 10 years ago. >Stop lights use filament light bulbs in northern climates because they don't frost up. LED stop lights have an optional heating element to defrost/de-ice the signal in cold areas, if the LED heat is not enough to do it alone. >Even if the LED's are better, there is still a need for hot filament light bulbs. LEDs are not exactly cool when they operate in applications like this. Have you seen the size of the heatsinks some of these larger LED bulb assemblies have on them? I don't hear people complaining that we need to go back to CRT-based televisions and monitors because having a filament (or three) in them made them better. People will pay extra in fact to get LED-based TVs and monitors over LCD ones. Like it or not, LEDs have replaced conventional lighting in most applications. The industry isn't going back to filament bulbs just like we're not going back to vacuum tubes instead of semiconductors. For better or for worse, that's just the way it's headed.
