Part 2 Luminaires for road and street lighting; and Part 3 Luminaires for floodlighting. In the formulation of this standard, assistance has been derived from CIE Publication No. 24 (TC ) on photometry of indoor type luminaires with tubular fluorcescent lamps issued by. and instrumentation for photometric measurements. For the photometry of fluorescent luminaires, the recommendations (as in BS Part 1: ) follow those of CIE Publication No. 24 (), Photometry of indoor type luminaires with tubular fluorescent lamps. However, this Standard also. A schematic illustration of the physical interactions involved is given in Figure which also identifies the sections of this Standard that specify the applicable requirements of this Standard apply principally to luminaires with tubular fluorescent lamps which are designed for use in-(a) exposed, semi-exposed and concealed. light and lighting - measurement and presentation of photometric data of lamps and luminaires - part 4: led lamps, modules and luminaires: en light and lighting - measurement and presentation of photometric data of lamps and luminaires - part 2: presentation of data for indoor and outdoor work places: i.s. en

  The present paper examines and compares the relative differences in energy savings and power factor of a number of dimmable LED luminaires and T5 fluorescent lamps when these are dimmed with photosensors. 2. Measurements. Two groups of luminaires were tested, one group (I) of LED luminaires and one group (II) of T5 tubular fluorescent lamps: •. Luminaire Calc. Type Units Avg. Max. Min. Avg./Min.

Guide to Using Compact Fluorescent Lights. Compact fluorescent lights have created a lot more flexibility, allowing fluorescent's to be used in recessed downlights, wall sconces, pendants, and just about any type of luminaire. Early compact fluorescent's were noisy, slow to start, and had a limited selection of color temperatures. Select the lamp that provides energy efficient Lighting Solutions: a. Use luminaires with energy efficient T5 fluorescent lamp instead of conventional 40 W FTL. Apart from excellent colour rendering properties, these lamps have higher luminous efficacy.

The modular type of retrofit compact fluorescent lamp is similar to the integral units, except that the lamp is replaceable.
