Hello,

I has a peanut bulb (it was stocked on my cabinet very very long time ago). I am thinking to use it but when I saw something in the instuction.

It says that it needed transformer? Why?

Also, it said the life that it will lasts is 60 Hz? Oh? I mean 2000 hours then 60 Hz?

:) Thanks

Hi bertus,

volts-12
amperes-i dont know
watts-20
watts = volts times amperes

so, how many amperes? :)

But the answer to one of your questions is that because it is a 12 volt bulb, you must not connect it to 120 volts. And to get 12volts from 120 volts, you must use a transformer.
