3D printed lampshades, what is the highest watt bulb I can use?

[LWiltshire]

Hello all, Appreciate a bit of help. I use the 3D printing pen to make bespoke furniture and digital 3D printing for the structure base. (Please see images below). I would like to make a lampshade with this hollowed style. Does anyone know the hottest bulb I could get away with for pla and would you recommend a different filament instead? Many thanks.

I had printed out a lamp shade using natural PLA, 1 pass thick, so it is very thin, used it over a compact florescent bulb 20 W and the top softened after 20 minutes. You may have luck with some 3-5 watt LED bulbs. If your design allows for airflow, it may be OK.
