New technology - When I was looking at this, I was thinking about the history of this wall. It might be close to 140 years old, now it has a high efficiency light bulb. I am pretty sure that it was lite by a regular tungsten bulb, may be an oil lamp, even a candle. Cheers JY

Playing with fire - Also, you could say combat fire with fire but it did not work in this case. Have a great day - JY

The tool - waiting for me on the counter top, I might open a good bottle of wine tonight cheers - JY
