Abstract
A fluorescent lamp fixture, or the lamp for use in such a fixture, has organic phosphor positioned to intercept a predetermined proportion of the radiations passing through the lamp envelope and to convert the intercepted radiations to longer wavelength radiations. The radiations passing the envelope which are not converted plus those radiations which are converted when blended together produce light suitable for illumination.
