en-ru -- история Philips -- PL and SL energy-saving lamps

[grey-hound-me.livejournal.com]

Уважаемые сообщники! Не могу разобраться с двумя аббревиатурами. Сначала решила, что первые лампы (PL) -- фотолюминесцентные, но не найдя расшифровки SL что-то уже и в этом сомневаюсь. На всякий случай абзац целиком:
It introduced the Compact Audio Cassette in 1963 and produced its first integrated circuits in 1965. The flow of exciting new products and ideas continued throughout the 1970s: research in lighting contributed to the new PL and SL energy-saving lamps; other key breakthroughs came in the processing, storage and transmission of images, sound and data where Philips Research made key breakthroughs, resulting in the inventions of the LaserVision optical disc, the Compact Disc and optical telecommunication systems.
Заранее спасибо за отклики.

Лампы PL - это длинные компактные лампы, с U-образной или W-образной трубкой без встроенного ПРА. SL - еще более компактные лампы с ПРА в цоколе. Источник (http://www.ies.org/PDF/100Papers/051.pdf). Русского эквивалента, пожалуй, нет.

Я мельком глянул, во многих серьезных книгах указывается, что PL и SL это разновидности CFL (compact fluorescent lamps.)

Вот краткие исторические справки:

RE: history of Philips

From "Karl Marx" on Wikipedia
Karl's mother, born Henrietta Pressburg (20 July 1788-30 November 1863), was a Dutch Jew who, unlike her husband, was only semi-literate. She claimed to suffer from "excessive mother love", devoting much time to her family, and insisting on cleanliness within her home.[18] She was from a prosperous business family. Her family later founded the company Philips Electronics: she was great-aunt to Anton and Gerard Philips, and great-great-aunt to Frits Philips. Her brother, Marx's uncle Benjamin Philips (1830-1900), was a wealthy banker and industrialist, who Karl and Jenny Marx would later often come rely upon for loans, while they were exiled in London.[19]

So does your (official, I presume) "History of the Philips Corporation" include such juicy details?
