To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
No flourescent bulb is made in the U. S. A. anymore, and I could be wrong, but I feel that basic standards of General Electric bulbs are way down and are no longer consistent. This bulb died within six months after it was first installed, which is generally good for an incandescent light bulb, however these are warrantied for five years. I have had General Electric flourescents that have worked well for over six years, and others that have worked for only a few months -- no consistency. I have had no such problem with SATCO flourescent bullbs, most of which have lasted for three years, or longer.
I ordered this two pack to replace lights that have been in my house for nine years. One of the replacement bulbs has dimmed to the point of my laundry room being too dark to see. The other light seems to work fine.
