Alphonso,
The light you’ll need for oyster mushrooms is not neon, but close to the colour temperature of natural sunlight. The important thing is that the light is a cool white colour and not a warm yellow colour that indoor lights often are. The colour temperature should be about 6,000 to 6,500 Kelvin.
See the following article and charts for more details:

I use an LED light that is approximately 6,000 to grow indoors. I will post a picture on the site.
Hope this helps.
