Yep, those and others (GAVITA) are releasing plasma bulbs right now. Too expensive for the moment.
Results Im aware of point up to excelent quality, but really not higher yields per watt burned than HPS. If they were no so expensive, they would be a nice alternative.
Notice that "plasma" lamps are actually induction (electrodeless) lamps, but HID ones (high intensity) while the lamps this thread was comenting are fluorescent induction (low pressure) ones. While with fluorescent induction the spectrum may be similar to that obtained by standard, with electrodes, fluorescents, with HIDs things change. Plama allows to get very different spectrums, but all being released for the moment are strongly greenish and with a relatively low red (especially deep red) emission (thats why the LiFi comes with deep red leds).
Right now the larger drawback of these lamps are the ballast losses, which are very significative and account for a way larger percentage in regards to bulb's power than with conventional HIDs. So when you ask a manufacturer about them, always ask for the system (ballast+bulb) power. They tend to forget to inform about it, you know.
Oldmac, Im glad to see you recovered and posting again. I hope all is right now for you :thumbsup:
