A very simple solution would be to use a higher-temperature solder to attach the bulb holder.
More information can be found from Kester at: http://www.kester.com/alloy_temp_chart.html
Basically you are looking for a lower Tin content in the solder you choose. For example, 05/95 Sn/Pb alloy has a 310 C melting point whereas the common 60/40 Sn/Pb alloy has a melting point ~ 185C.
Even the increasingly common "lead free" Sn/Ag alloys will have a slightly improved melting temperature over the common 60/40 alloys.
best of luck!
