It is also noted that the lighting report recommends a new lighting scheme to the St Johns Chapel
Full running costs and wattages have not been detailed within the SLS report so detailed costs and
savings cannot be calculated however it can reasonably be estimated that by upgrading all the above
lighting (both bulb changes and fitting changes) savings of around 50% will be achieved saving the
church around £3,000 per year on electrical costs. In addition the proposed new lights (both bulbs
and fittings) are much longer life and would therefore also provide a maintenance saving from
reduce lamp replacements.
