Comparing colour discrimination and proofreading performance under compact fluorescent and halogen lamp lighting.
UNLABELLED Legislation in many countries has banned inefficient household lighting. Consequently, classic incandescent lamps have to be replaced by more efficient alternatives such as halogen and compact fluorescent lamps (CFL). Alternatives differ in their spectral power distributions, implying colour-rendering differences. Participants performed a colour discrimination task - the Farnsworth-M...
متن کاملThe effect of compact fluorescent lamp and curcumin on wound healing in Wistar Rats
Background: Nowadays, the rapid recovery of skin lesions and functional return are among the goals of researchers. The skin is the first defensive barrier against microorganisms in the body and its failure causes infection to spread in all systems of the body. By taking into account the contradictory results of previous studies on the impact of phototherapy on wound healing and also the conside...

متن کاملRandomized controlled trial of compact fluorescent lamp versus standard phototherapy for the treatment of neonatal hyperbilirubinemia.
BACKGROUND Special blue tube lights of standard length are used in most neonatal units to deliver phototherapy. Of late, special blue compact fluorescent lamp phototherapy equipments have been introduced in India, which are claimed to be better than standard tube lights. AIM To compare special blue compact fluorescent lamp (CFL) phototherapy with special blue standard-length tube lights (STL)...
متن کاملAn Improved Microscope Lamp.
The new inclined binocular microscopes when used with high-power objectives require much light to illuminate adequately the field of view. At least three times the light is necessary as for a similar optical combination on a monocular instrument. The ordinary opal bulbs even when over-run do not provide sufficient illumination, and of course with them there is no possibility of employing a ligh...
