An Electrical Mystery

I have received an e-mail from Alan Davies with a bit of mystery. Alan writes:

“I have seen two of these labels at properties in Penydarren, Merthyr
that I have worked in, at the fuse box location. I thought a photo may be of
small interest. I wondered if perhaps the customer was able to have three
lights installed for free, provided you paid the electric company for the
electric consumed!”

Can you shed any light (sorry!) on the mystery?

If anyone has any information on this, please get in touch.

  1. The Company that ran the Merthyr trams also supplied electricity in the local area. The Electricity was generated in the Traction Yard in Penydarren which was also the tram depot.
