In practice, you can touch the bulb without gloves, you do not burn yourself changing it just after switching off, and the fixture stays cool to the touch.

Look instead for the luminous flux in lumens on the packaging, and compare like with like. Four points to check before ordering: the fixture voltage, the stated power and flux, the dimensions of the socket, and compatibility with an old dimmer.
