2-step bins are offered in 2700K, 3000K, 3500K, and 4000K and are now available in sample and production quantities. These breakthroughs in production processes increase the quality and consistency of white LED lighting to a level beyond that of many traditional lamp sources and in theory at no extra cost. These new breakthroughs in LED manufacturing highlight an issue with Standards and Standards bodies: that by the time standards are put in place they are outdated. It is now probably time to raise the standard of LED products in the marketplace by revising the ANSI C78.377 to have much smaller bin sizes. This standard should also be applied to other light sources so that any products in the market place that do not meet them cannot be sold. Enforcing such standards would yield improvements in end-user satisfaction and ensure only quality products are sold in Europe.

Although most of the R&D attention is focussed on white LED improvements the team at OSRAM have made a significant breakthrough in their laboratories by increasing the efficiency performance of their thin-film red LEDs by up to 30%. The latest generation of thin-film chips benefit from an optimized chip platform which has potential for further improvements. This boost in efficiency will open up new LED applications in general illumination, micro projectors and the industrial sector. The record efficiency was achieved for an LED of 119 lm/W at an operating current of 350 mA (136 lm/W at 70mA) by the latest generation of a red 1 mm2
thin-film chip

(InGaAlP) as shown in figure 8. The chip was accommodated in a Golden Dragon Plus package and emits at a wavelength of 615
nm (λ dominant). The LEDs efficiency has been measured at 44% (49% at 70mA), and even exceeds 50% for a wavelength of 642 nm.
The improved performance of the LEDs greatly expands the possible applications for red LED light sources. For example, exceptionally high efficiency means that warm white LED solutions can be produced with better quality of light and a better energy balance through colour mixing than through the usual conversion of blue light The performance compares favourably to those red LEDs currently in production, for example the highest bin from the Cree XP-E is 73.9 lumens and 50 lumens from the Philips Rebel at 350mA.
Colour tuneable LED Lighting Fixtures ENFIS from the UK was exhibiting at the Guangzhou fair their latest range of UNO Plus Products complete with drivers, optics and thermal management.
Following an increasing trend of colour tuneable lighting fixtures ENFIS launched a high-quality, tuneable, efficient, LED light engine range suitable for integration into smaller standard fixture sizes such as AR111 or AR70 as well as spotlights and downlighters.
The 40W modules shown in figure 9 are available in the following versions: • High CRI tuneable: >90 CRI from 3000K to 6000K
• Warm white tuneable: 1800K to 4100K • RGBW: 3000K - 6500K + full RGB Combing high illumination, with such a versatile, high quality output in a compact form factor, these products enable lighting designers and fixture manufacturers to create a huge range of effects and moods and for architectural, hospitality,
