A sample of about 150 elliptical galaxies taken from a survey of Burstein et al. (1987), which includes also new CCD photometric data, is examined. The fits of total luminosity versus three different diameter indicators, i.e., the effective diameter D(e), the D(n) diameter proposed by Dressler et al. (1987), and the isophotal diameter D(0) at 25 mag arc/sq sec, had given no sign of environmental effect on such quantities. A comparison with previous results based on lower quality data was carried out in order to check the reliability of different photometries and statical tools used. The main conclusion is that the luminosity-diameter relation seems to be universal in the range of luminosities spanned by the sample; so environmental effects, if present, must be smaller than observational errors.
