    Cold Cathode - CCFL

    Why is nobody using cold cathode fluorescent light? Is it not efficient or something? You know, companies will make any wavelength or spectrum you so desire. I desire the good ones that aren't available in other kinds of lighting.

    Cold Cathode - CCFL

    I just don't see the application.. The intensity isn't there.

    More intensity than LEDs by far, yet we've run off and gotten all happy about them. I really like the idea of picking your spectrum or wavelength. Hitting it right on the spike would be a huge advantage. Big increase in efficiency I think.

    That would make no sense...

    Remember the good ol' days?

    Even with the LED UFO i have here in our store the plant that is under it (Burgmansia in coco) is continuing to flower...

    We'll see in the months to come i guess.. :thumbsup:

    Cold Cathode - CCFL

    heh touche.. I've gotten wind of 2 inch diameter LED's that are supposed to be the new wave of LED lighting, so the next few years will be interesting to say the least...

    Suppose there's always a turning point for everyone...Just have to see it applied before I can really take a side.

    ... Like LED's.


    Stay Stoned,

    ya i definitely agree. they would be more widespread though if they could

    Cold Cathode - CCFL

    "Cold cathode devices typically use a complex high-voltage power supply with some mechanism for limiting current flow. Although creating the initial space charge and the first arc of current through the tube may require a very high voltage, once the tube begins to heat up, the resistance to current flow begins to drop, requiring a gradually lower voltage to maintain operation. In the case of tubes with an ionizing gas, the gas can become a very hot plasma where electical resistance greatly reduced. If operated from a simple power supply without current limiting, this reduction in operational resistance would lead to damage to the power supply or the tube electrodes from overheating."

    So it'd require a specific power supply from what i understand otherwise the life of the light would be greatly reduced. The question is, how do plants react to it? How many will you need? Would it be a combination of specific spectrum's, like LED's ?

    I've never seen CCFL applied to plants.. anyone?

    :thumbsup:

    Thanks for the additional info. I've not seen any grow info about CCFL growing plants, and I have looked a little. I'll bet there's some out there some where.

    Either there are.. or there will be ... wink wink , nudge nudge.

    Ive been surfin the web and i havent found anything about growing with ccfl's.

    But I think it could be possible
