[BCMA] Impact of partial changeover to LED lighting

[Moderated BCMA subscriber listserv.]

Thank you very much for sharing this info. There is no signature to your message so I don't know your display requirements for colour rendition; 2700 k sounds like an awfully warm colour temperature.

It would also be good to know how this affects your heating costs during the winter months since there is less radiant and conductive heat generated by the LEDs.

Over the previous 9 years our average daily consumption over the month of May was 205kwh, with the lowest being 148kwh, this current May we are down to a daily average of 88kwh.

The drawback is the upfront cost of around $35 a bulb, but we estimate a return of about 1.5 – 2 years. Because of the potential impact on our annual operating cost, our local Lion’s are considering financing some of the change over.
