抄録

Mercury-free HPS 150W lamp with high CRI operated on inductive ballast was developed. It has a slender arc tube with high-pressure xenon gas compared with that of mercury-contained arc tube. It has nearly the same haracteristics as those of mercury-contained HPS lamp with high CRI and shows nearly the same hue as that of incandescent lamp. This lamp is suitable for general lighting, such as indoor lighting, flood lighting, street lighting and so on. We present another one application, that is, seedling growth by supplemental lighting. We examined with lettuce and broccoli and got good results by 2 hours supplemental lighting before sunrise, compared with those of only daylight.
