I just checked, there's nothing on the ballast that mentions Amperage or Volts or anything at all except a label that says Hamilton Technologies and a warning sticker about turning it off before you reach into your aquarium.
Here's another question, how hot do ballasts run? Are they just warm like a flourescent ballast or way hotter? Since this is the lowland tank a little heat from the ballast and bulb will give me a higher temp (currently it's only 75*Fd/70*Fn) and the old terrarium was 20*F hotter (and twice as bright) during the day and the plants loved it, oozing with nectar. Now no nectar and the latest pitchers are slightly less impressive as compared to the furious growth they had just days before moving them.

The more modern, the more effecient, so the less warm. Check this out

Hi Khai,
you should offer your knowledge to those designing MH lamps and electronics for those lamps here in Europe! The guys from Philips and others doesn't seem to know the facts and build ignition circuits for 70W MH lamps producing 4-5kV ignition pulses...
Joachim
P.S.: Current is measured in Ampere and voltage is measured in Volt!

I think you need to read these Joachim.

Yes Ive seen that and its is only in reference to pulse start!
As you will notice the header at the begining of the paragraph,"Pulse-start Technology"!
Also the title of the article is "Metal Halide - Advances & Improvements".
"By David Houghton, PE, Contributing Editor, Architectural Lighting Magazine"
Where does it say anything about these RECENT technologies be used in Agriculture?

OK, last try - I do dislike this discussion! This is the datasheet of the MH lamp I'm running for my Nepenthes:

Of course the manufacturer could be wrong demanding these ignition voltages for his products.
It is no problem you don't know all and you'll propably know that not all information on the internet is true - but persisting on wrong information is somewhat strange to me. The site mentioned above explains how these lamps work.
