SUMMARY Excluding LEDs, we likely can expect a continuing decline in the number of lamp and ballast developments as LED lighting systems are now reaching efficacy and efficiency levels suited for general lighting. But LED systems will remain expensive, and until we are prepared to pay 10 cents per lumen for our lighting gear, conventional lamps will still be popular.
Controls, on the other hand, offer a new dimension to energy efficiency. Too many buildings have been written off as uncontrollable because of the high cost of retrofitting high-performance controls. Developers of mesh networks and other wireless systems know that cost-effective wireless controls will be a huge business as the need to control lighting becomes essential. In new buildings, I personally like the reliability of wiring, and digital lighting systems using DALI and related technologies. They are the only way to build buildings in the future.
