well if you take a little time to investigate you will find two complete grow cycles published, all the other specifics are in the product literature provided on the site and are public available at Luxim. But yes, I think you miss a few things
I'm not saying at all that plasma will now replace HPS and I am certainly not saying that is is cheap. I'm not saying that with plasma you have a golden bullet. There is a much more development to be done to optimize plasma light for blooming for example, and to learn how to grow under plasma.
On the other hand in the vegetative stage we have seen incredible results that outperform HPS, MH, CFL or any combination of them. That we have tested and repeated grows and tests have confirmed that. Also we could reproduce the increased dry mass in every test grow so far. We had less yield than the other combinations (plasma/HPS, MH/HPS). The buds however were most compact, even deep in the plant with both plasma grows, the plasma only as well as the plasma/HPS combination, the latter delivered the best buds at high yield.
So for who is this light? Let's face it, it's not for you if you are growing on a tight budget or want to save money or electricity. It's an expensive piece of equipment. But if you want to keep up with current technological developments and want to experience what it means to be growing with plasma lights and have applications for them for cuttings, mother, vegetative growth or as additional lighting together with HPS to improve the quality of the product, if you are scientifically interested or if you just want to have it because it is such a cool lamp, then I'd say this horticultural quality fixture is an excellent choice.
You also need to consider that in our industry we are sometimes a bit faster with some developments than in the horticultural market. So a lot of products nowadays see this market probably a bit faster because many pot growers are open minded growers who really want to crack "the code".
Plasma is a product that is in the beginning of it's development cycle. I think this is the first usable solid state plasma light. Over time other, and more powerful models will be launched, if the market will accept these lights.
Plasma is also used in street lighting, theater lights etc etc, so there are numerous applications. Growing plants with them is just one of them. If the development of this lamp would have to rely on turn-over in horticultural lighting there would be no development at all
.
The power use is 300 watt btw. The module itself takes 28V, 9,3 amps so 120V power supplies are possible.
