GoodBulb6-Watt 9 Inch T5 Fluorescent Light Bulb | 4100K Cool White Medium Bi-Pin Base | 240 Lumens 65 CRI 6000 Life Hours | Instant/Programmed Start | Pack of 20 Bulbs

About 15 years ago I installed three fixtures using this rare type of bulb in my home office. The last time I was able to locate replacement bulbs locally was 50 miles away, at a price of $90 for 16 bulbs. Goodbulb provided 2.5 times as many at just 1.7 times the cost. The 40 bulbs all arrived early, intact, very well-packed and easy to extract one-at-a-time as existing bulbs wear out. They stand an excellent chance of lasting me for altogether several years.Best of all, Goodbulb contributes a portion of their profits to provide lighting to people around the world living without a local electrical grid. This demonstrates for me how much they genuinely care.

Great product. Fast, safe shipping -- packaging was excellent, not one broken bulb. They work great and were a good price. I will definitely purchase again in the near future.

Our batting facility needed light bulbs and none of the big box stores had what we needed. Order arrived quickly and in good condition. Thank you!

Get what you need at a good price, while helping a small private business who also gives back, giving a portion of proceeds to bring light to folks without electricity! Really, buying from GoodBulb checks all the boxes!

Came packaged carefully (double boxed with bubble wrap). Replaced all 46 bulbs in our body shop and it’s so bright. 2 thumbs up. Boss liked it so well, I had to get another box for our main shop.

Good Bulb was very easy to deal with they kept us informed about our order. Prompt shipping times and seemsto be a quality product. We were planning on adding more light fixtures but after using their bulbs there is no need.The bulbs are well boxed for shipping so we received them with no damage.

Bright as daytime light.

Got what I wanted and they came quickly.
