Are negative ions bad for plants?

I have an interesting question for you scientists out there!
Have you heard of a Anion Air-Purifying Lamp?
Its a type of energy saving light bulb that emits 6400k light which is the right type for vegatative growth.Besides low cost full spectrum illumination this unique energy saving lamp creates a large quantity of negative ions (anion) to freshen the air and has other characteristics as belows:-

Elimination of poisons:
​

eliminate harmful airborne bacteria and virus, various poisonous volatilizing chemicals in the air (such as benzene, toluene, formaldehyde, ammonia etc).

​

Elimination of smell:​

Rapidly dispel the smoke in the air.



- Long Life upto 8,000/10,000 hours long life 1-year guarantee.

- Lasts upto 7 years, based on 3.5 hours maximum usage per day.

- Energy efficient save upto 75% in energy costs.

Phosphors Power enhance lumen efficiency and colour rendering.

High light output.
