You need only a few extensron due to low efficiency and short bulb life. They are appropriate, however, in situations requiring intermittent use, short—duty cycles of less than one hour, or good color rendition. Sodium vapor lamps: (orange light) Developed for industrial and street lighting, these are very efficient and provide long bulb life. They are not recommended for landscape lighting, because they make objects appear yellow or grey. They may be suitable for long-duty cycles when good color is not required. Compact fluorescent lamps: These high-efficiency lamps were developed as an efficient replacement for indoor and outdoor incandescent lamps. They are long lived and produce light similar to incandescents without flicker or hum. Outdoors, they should be electronically ballasted and rated for 0' F. V é fa.
