In short, working with a UK manufacturer, I had to have a luminaire designed from scratch that would (a) produce a high lumen output package to minimise the amount of luminaires required; (b) be able to cope with the hostile environment that a swimming pool creates; (c) create as little internal heat as possible to ensure as long a lamp-life as possible; and (d) use as little energy as possible.
Thankfully the manufacturer and I were able to come up with a solution that ticked all the boxes; and although it wasn’t an LED solution, it still managed to achieve an impressive efficiency of over 100 lumens per watt; and at the time (in 2014), this was exceptional.
This was one of my most challenging projects to date. This came to me from A&B Engineering (Liverpool) when they were looking at the original scheme that had been specified. They had noticed that the original scheme (done by a prominent lighting manufacturer) was not actually able to be installed as per their scheme. As is the case in many projects, the lighting part of the installation is not considered until everything else has been decided upon; and the original lighting scheme had luminaires in positions that were not achievable – mainly due to the large ventilation system and the lack of clear wall space; as it was a heavily glazed venue.
