togol you are close there.

the electric discarge lighting it pretty wide area to cover but most common used is the neon lighting , flourscent lightbulb, HID aka HPS, MH , MV, LPS and arc lights

and most electric discharge lighting is useally regulated by ballast both electronic and mangatinic but some just used plain restitors on DC system

Merci , Marc

And with arc lights, as frenchelectrician mentioned, you may include a very common one, the xenon short-arc lamp as used in cinema projectors world-wide. smile

Some examples HERE

In addition to Tom, Marc and Tony's replies, how about these descriptions:

Discharge Lighting...

Lighting from Lamps which do not use Resistance Elements (AKA Fillaments) to DIRECTLY produce Light output, via emissions from the filament only - as with Incandescent Lamps
(Incandescents are mostly a heat / Infrared Light Generator, with White Light being a "Byproduct").

Or:

Lighting produced via a Plasma contained within an arc tube, with Light output produced from Photons emitted from inert materials in the arc tube, due to a controlled level of current knocking the Photons loose from the inert materials, while the current flows from one Cathode, through the arc tube, and collects in the other Cathode.

Or:

Lighting from Lamps having "Negative Resistance" Characteristics, as opposed to Lamps with a "Linear Resistance" Characteristic - as would be found in Resistance (Filimant) type Lamps - AKA Incandescent Lamps.

Or: (last one)

Lamps which require the Current to be "Ballasted" (automatically regulated) by an external or separate device, in order to operate correctly (and not self destruct instantly); as opposed to Filament Lamps, which do not normally require the Current to be "Ballasted" - due to the Linear Resistance of the Filament.

I have more, but these are boring enough! wink

I like this one...

."

as it contains the most authentic electrical gibberish LOL
