Here we are not going to overload with comparrisons
between Neon (cold cathode), against other light
sources other than to state that in 2011 the UL energy
authority in the USA.Had tested & rated neon
(cold cathode) as the greenest light source available.
The Iron Core / ElectricoMenchanical Transformer
The simple fact is that a 15kv 30ma neon transformer draws
1.9 amps of power but it can be power factor corrected to
.9amps when fitted with a capacitor.
For australian calculations
Volts x Amps - Watts
240v x .9 amps = 216 watts
With a footage chart 27.7 mtrs of 15mm diameter argon mix
can be run on a 15kv transformer this equates to 7.8 watts
per mtr of tube. with neon gas it is 10.9 watts per mtr. With
glass diameter reducing in size increases the watts per mtr
used. Although the small diameter tube looks brighter it has
less light(lumens) output
Electronic Transformer / Neon Power Supply Unit
The maximum size of a PSU is 12kv output a 12kv 25ma
PSU draws a maximum of 108 watts to operate 12mtrs of
15mm diameter argon mix this equates to 5.4 watts per mtr
of tube. with neon gas it is 10.5 watts per mtr. With glass
diameter reducing in size increases the watts per mtr used.
Although the small diameter tube looks brighter it has less
light(lumens) output
