The Plama uses a “Globe” or “Bulb” rather than our technology which is hundreds of special LEDs which provide the wavelength and frequency output of the original Beam Ray light.
The Bulb light is transferring frequencies into light, our LED technology is also doing this function but through more modern Light technology.
The difference really is price. The bulb would be quite expensive, as it uses expensive technology to create the glass blown bulb.
The glass is extremely fragile, any knocks will damage it easily, and a broken bulb is not covered by their warranty.
