Lytespan 7, a new four circuit power track from Concord Lighting International - providing four seperately switched circuits in one track - was the lone British winner of a 1972 Gute Form prize - it was poached in a field in which German companies reckon to be very strong. Also cited in Concord's award were the Eurospot and Powerflood (1971 CoID Design Award winner) lights. Design of all three prodcuts is by the company's design team with consultant designer Robert Heritage.

Lytespan 7 is a little wider and deeper than the present single circuit Lytespan 2. It is made in the same way from extruded aluminium profile, the coppered contact strips shrouded in and insulating plastics extrusion proof against prying fingers. A new feature of Lytespan 7 is that the special contact shoe, supplied attached to Concord's own lights or as a seperate item for wiring other appliances, is totally contained within the track's dimension. By a number of jointing devices, live ends and stops Lytespan 7 can be laid continuously up walls and across ceilings and round corners horizontally. It can be supplied with a flange for concealed fitting and can be mounted direct to a surface, offset, or pendant.

Lytespan 7 allows a total electrical load of 10 1/2 kW (three phase) or 7 1/2 kW (single phase). Also shown is Concord's new Pan-parabolic spotlight designed for easy rebulbing and cheaper production.
