Bests & Worsts Reviews from Amazon

I've been looking to buy a full spectrum lightbulb for at least a year, I had finally decided on norbsmile but after using this bulb for exactly One month I am disappointed ☹️. I believe the light bulb is a full spectrum bulb Although I have had no actual way to test this There's just something different about the light, A difference you can feel. But For about 5 days now, the bulb has been flashing as if it is slowly dying, this is simply unacceptable from a brand new bulb that costs 20 dollars.
