91 The Lighting Handbook Fluorescent lamps – High very high luminous efficiency (especially T16 HE) – Good very good colour rendering – Long service life – Wide selection standard ranges – Dimmable – Use: efficient wide-area lighting Functional description An alternating electrical field between two electrodes the discharge tube produces invisible radiation. The tube’s white fluorescent coating converts this radiation into high-quality, visible light. T26 T16-R(I) T16-I T16 T16-D . The luminous flux fluorescent lamps is highly dependent their operating position and ambient temperature. Lamps that use amalgam technology are optimised for use in environments where there are fluctuating temperatures (see page 97). These lamps need ignitors and current limiting; these functions are combined in an electronic ballast
