Tackling the technology

Dear Editor,
A funny thing happened to me the other day. I was on the phone to a contractor who was not too pleased that the LED sources he was installing did not appear to work. Not being the kind of company to let this be an issue, we rushed to site to find he had cut the fitting in half to make it fit into the recess.

This, as you can imagine, can have an impact on the effectiveness of the heatsink. It may make the LED overheat and fail.

It gets worse. The product was an intelligent fitting with CRI monitoring built in. You guessed it… to hold the fitting they took it apart and reassembled it upside down and back to front. It’s fixed now, but blimey contractors, get a grip. Preferably not around our fittings.

This made me think of all the daft things I have seen and heard over the 26 years of my lighting career. Like the day we were asked why the low voltage wall light supplied did not work and kept blowing the lamp. All I said was where is the transformer housed? The line went dead.

Or… ‘The lenses on these CDMR lamps have fallen off.’ ‘What lenses?’ ‘The ones on the front that fell off when the lights went very bright and we had to switch them off.’ ‘Errrmm, CDMR lamps have no detachable lenses.’ ‘Errr, yes they do,’ says the sparky. Oh, no. ‘Where are the black boxes we supplied with these lights?’ ‘On the floor,’ says said sparky. ‘How the hell have you run the cables from them to the fittings in the ceiling?’ says I. ‘Hello, hello, hello…’

So it’s not just an LED issue, it’s a new technology issue. Can’t wait till we start making nuclear fusion lamps.

Yours faithfully,
Paul Cox

London Lighting the unseen buildings

Dear Editor,
Pick up any magazine and there are photos of wonderfully lit buildings by the UK’s top designers. For those without a designer, there is plenty of advice in the series of Lighting Guides produced by the Society of Light and Lighting.

The need for a lighting review

Dear Sir,
We need to change the way that we assess project costs.
