There are two types of electrodless induction lighting one being plasma with no phospors and the other being fluorescent with phosphor blends.
plasma in the US is made of argon/metal halide and not sulphur it operates through rf magneticinduction like a fluorescent induction but with a core temperature of 725 degrees c. This means shorter life spans fluorescent induction. I've not been able to find any journals or grow pics using either type of plasma for grows which on the other hand I have seen for fluorescent induction systems.
Take a look at the plasma PAR values and you'll see it's good for clone and veg but won't emit anything north of 500 nanometers so the IR levels that are required for flower and bud will be down from fluorescent induction or HPS. While the energy coming out of plasma is very high in lumens per watt and it is efficient at delivering the light down to the plants surface it is most effective in a 3' x 3' area. To increase the area the lamp must be raised and the subsequent reduction in PAR is an unfortunate consequence of that adjustment.
The fluorescent induction grow lights utilize phosphor blends that show PAR peaks at 300 and 700 nanometers so the plant is getting the UV and IR absorption levels it needs most at considerably less expense and with better canopy penetration. Plasma emissions peak between these ranges which while good for the human eye are not PAR ranges that a plant benefits from utilizing a single lamp type for the entire grow.
There are alot of really good reasons (low wattage, high lumens, low operating temps, long life spans) to consider induction lighting system over HID or conventional fluorescent but until more is known about plasma induction systems for our industry I would stay with fluorescent induction.
