I am seeking advice from forum contributors about replacement lighting for a village hall. The hall is approx 15m x 6m and has a high vaulted ceiling with four timber roof trusses (see pictures here http://www.hunsdonvillagehall.org/facilities). It has mixed use from Badminton and carpet bowls which need good lighting levels, to parties and performances which need reduced lighting levels. The existing light fittings are 8ft twin T12? fluorescent fittings with wire guards. These are fine for Carpet Bowls and Badminton but are too bright for parties etc. there are currently four banks of two fittings each on a separate switch wire(4 switches).
We have asked local electricians for quotations to replace these as the 8ft tubes are more or less obsolete and we need some "mood" lighting for non sporting events. My brief for quotations was for dimmable fluorescents controlled in two banks (left and right of hall) on the basis this would free up two switch wires which could then be used for "Mood" lighting
One electrician has quoted for 4 banks of 5ft T8 twin fluorescents with dimmable control gear and ballasts, plus some 50w Halogen spotlights on each of the timber trusses which shine up to the ceiling like a wall wash effect. In addition he is to fit some colour changing led flexible strips along the timber bearers as additional mood lights for discos christmas etc
The second electrician has specified 4 banks of 6ft T8 twin dimmable fluorescents with some 100w spotlights on a track system, presumably to run horizontal along the timber bearers between the trusses. Both quotes have come in around £4500-£4800.
My first question is the light output of the two quotes. Assuming both have daylight tubes is the light output from the 5ft fittings comparable with the existing 8Ft 125w T12 fittings or do we need to go to 6ft T8 fittings.
Secondly the badminton club always complain about the lights being an obstruction to play. We could possibly put the lights longitudinally with the orientation of the court but that would mean additional high level mounting points and long chains. Are there alternative circular light fittings which would provide the same light output and light coverage as fluorescents and are these dimmable. For example these type of High Bay warehouse lamps with a metal halide bulb or HPS lamp rather than LED http://www.ukledlightingdirect.com/100w-acrylic-led-highbay-light.html. How do these compare price wise with a 6Ft twin fluorescent with dimmable ballast or are they much more expensive.
Lots of questions but we really need some advice
Many thanks
