The problem is often the light fitting itself and not necessarily the components you fit into it.
If you fit any of any kind of bulb in a recessed downlighter fitting then expect it to get hot as there is often insufficient free air ventilation. Replace your fitting for something well designed for LEDs then you stand a better chance of obtaining long life.
The OP is looking for replacement tubes and they are more likely to run cool in tat kind of fitting.
Some designs of LED light power supplies do take heat into consideration by monitoring the temperature and reducing the current to the LED when it starts getting too hot. This also will reduce the light output. Unfortunately it is virtually impossible to tell what kind of power conditioning has been used in most LED lights without stripping it down (and probably destroying it)
