[GreenYes] Non-mercury fluorescent lamps

[Alan Muller <amuller@no.address>]

The industry position 
(http://www.nema.org/gov/ehs/committees/lamps/upload/Lamp%20Brochure%20Final%203%2005.DOC) 
has been that non-mercury fluorescents are impossible or impracticable.

Even a casual Google search suggests that this is not the case:

A New-type of Xenon-Neon Barrier Discharge Fluorescent Lamps: Double 
Helical External Electrodes Lamp (DHEL)

M. JINNO, Y. MUGURUMA, T. MATSUDA, H. MOTOMURA and S. TAKUBO

Recently as interests in environmental issues increase, demands for 
mercury-free fluorescent lamps are increasing because mercury is 
harmful to human beings and creatures. As one of the solutions of 
this issue the authors have developed a new-type of mercury-free 
fluorescent lamps using double helical external electrodes. In this 
paper the fundamental characteristics of Xenon-Neon discharge in the 
Double Helical External Electrodes Lamps (DHEL) such as the 
luminance, power consumption and lamp current are investigated. When 
the pressure ratio of Xe : Ne was fixed at 7 : 3, total pressure at 
1.33 kPa and external electrode pitch as 10 mm, luminance over 10000 
cd / m2 is achieved. In addition as a prototype 1 m length DHEL is 
prepared and demonstrated to show basically there is no limit in 
length of DHEL.

KEYWORDS : barrier discharge, mercury-free, fluorescent lamp, xenon, 
external electrode, DHEL

To some extent they are already commercially available:
