a quick check with the meter gave 20V AC. thats how it was designed
to light the bulb .

my question is can you have the double insulated symbol on a product
with exposed 20V AC conductors?

AFAIK, 24V and less is considered low voltage and not a code problem. It is
often used for controls in industrial products for the same reason.
