This sweet little church was originally built in the 12th century but this window dates from the 13th century. So many churches of this age have similar light fittings but not sure of the age of the lights as many additions have been made over the years. Electricity to the lamp was obviously added at a much later date.
Lovely stained glass windows. Not many of those where I live and they are usually more modern in design when I do see them. The lamps remind me of oil lamps that I've seen in places. I agree with @kametty that you were able to photograph the interior of this church very well.
Favulous composition for symmetry
