Vertical integration will scupper compatibility

Dear Sir,

I can see the appeal of vertical integration for large manufacturers. Not only do they get the order for the whole job, it reduces costs and technical development can be co-ordinated a lot more easily. There might even be some bene t to the user inasmuch as if anything goes wrong, there is just one manufacturer to call.

However, we all know that real savings in energy will only come from intelligent switching and dimming by using technologies such as daylight controls, movement sensors and illuminance detectors.

My worry is that the vertically integrated manufacturers will have no incentive to make their control systems compatible with others. A facilities manager might want a particular control system for the lighting so it can be integrated with the building management system. Similarly, the designer might want a particular driver or ballast for its technical characteristics or build quality.

Vertical integration will make life dif cult for small and medium sized manufacturers because their equipment will need to integrate with proprietary systems.

Do we really want every single piece of lighting equipment in a building to be supplied by just one manufacturer?

It’s not all about LEDs

Dear Editor,

Congratulations on the first issue of Lux magazine. While I applaud the emphasis on low-energy lighting and the focus on refurbishment and retrofit projects rather than new build, I would take issue with your heavy emphasis on LEDs and indeed OLEDs.

Light hidden under a bushel

Dear Editor,

I have just read the article on ‘How to light a home to Part L1’. In fact, you don’t need to hide all the energy- saving lighting, as Franklite has proved by lighting the Green House for Huntingdonshire District Council.
