If someone wants to use this bulbs in a paper lamp, I can only advise you, since this very hot in a short time (70 ° C for 15 min, 82 ° C for 30 minutes, as measured by the "heat sink" of the light bulb). But with increasing temperature decreases the power consumption, ie the bulb dims itself by itself down.
Conclusion: Personally, I would again grow me this bulb, but it also depends on the purpose of it on!
