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.
It's a little too early (just a few days after installing these lamps) to know if they will perform well, but so far, so good. Will update this review if they fink out on me in a short time. Am used to buying GE brand replacement lamps, and they usually last a couple years. I don't know WHY this type of lamp is made the way it is, because it takes patience and high I.Q. to psych out how to insert and remove the dang things! Once I learned the trick, I actually wrote it down on the packaging, so it will be less aggravating next time I replace the light tube: To remove, you twist the tube TOWARD YOU and PULL DOWN; to install, you push the tube AWAY FROM YOU and twist.
The light seems OK; I ordered WARM and am not sure I got WARM but it's a good bright light, so that's what counts.
Good luck to anybody who's also confused/mystified about how to remove/replace these tricky little fellers!
UPDATE: October 2019 It's been about 10 months and the light's still shining bright. :-)
These bulbs are a very good value. They come expertly packaged However, the color is a little off. They are suppose to be a warm light but they do not match the other warm light bulbs I currently have. Granted they are a different company but warm light should be the same across the board. The difference is very noticeable so not sure what I will do.
Ordered two bulbs only one works. That's it in a nutshell.
The non-broken bulb worked out fine in terms of brightness and color tone. Both bulbs has "rain stick" like particles making noise in them and when I tried both bulbs only one worked. I am concerned that the functional bulb may have a lower life expectancy.
Note: the package was not damaged in any manner and the box had plenty of protection.
The label on packing says 3000K. When I looked up the Part number on their website, it says 2700K. But when installed the light is was notably brighter than other 3000K tubes. Go figure. Glad I can easily return...
