    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!

    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:

    http://www.blv-licht.de/images/BLVMedia0018305.PDF

    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.

    Is there really a point to arguing whether or not a HID lamp takes 2.5kv or 4kv to light?
    Is that a Nepenthes in your pocket or you just happy to see me?
