Hystrix canopy declined slightly at the midday, suggesting the occurrence of reversible photoinhibition. Owing to the lower maximum net photosynthetic rate in sun leaves and the ability to effectively and consistently utilize the scattered light and/or transmitted light, C. hystrix saplings could survive low light intensity, grow well at the edge of the forest and in the understorey, and eventually become one of the dominant species in upper layer of the community.

Recently a third hybrid light-emitting layer has been developed that uses nonconductive polymers doped with light-emitting, conductive molecules. The polymer is used for its production and mechanical advantages without worrying about optical properties. The small molecules then emit the light and have the same longevity that they have in the SM-OLEDs.

近十几年来，随着人们对半导体发光材料研究的不断深入，LED制造工艺的不断进步和新材料的开发和应用，各种颜色的超高亮度LED取得了突破性进展。1993年，开发出来的以蓝宝石为衬底的GaNLED就是典型代表，它能发出绿光、蓝光和紫罗兰光。

Although LEDs do experience a gradual and permanent reduction in light output during their normal operating life - caused either by a reduction in the light-generating efficiency of the LED die, or a reduction of the optical path within the LED package - the Dialight street LEDs are expected to provide about 70 per cent of their original light output after 50,000 hours or 10 years, provided that they are not overdriven.

在正常操作下，LED必需要经历光输出逐渐减少的过程，而这个过程是会一直持续着的。导致光输出减少的原因可能是由于LED产生光的效率在降低，或者是由于LED压缩包内的光径在减少。不过，只要没有超负荷使用，Dialigh的LED路灯在工作50，000小时或10年后，还可以达到70%原始光输出的能力。
