I have a covered lampholder (light socket) outside my house that I want to use to temporarily power a plug-in string of indoor/outdoor lights. Using CFLs, the total wattage of the string of lights will be lower than the rated wattage (100 W) of the lampholder.
The string of lights uses a grounded (three-prong) plug. Is there a way to safely power this using the lampholder?
I can't find any lampholder-to-outlet adapters that give you a grounded outlet. Are there any?
Would it be safe to use a two-prong lampholder-to-outlet adapter with a two- to three-prong grounding adapter? Is there anything I can do to make it safer? Keep in mind that this is outdoors, under small cover.
