Not your standard light bulb.
It was a very odd light bulb, and I was afraid I would not be able to find it. The item arrived on time and waswell packed and was exactly what I needed.

Good replacement for an old fluorescent bulb, but make sure the base is the same
After 25 years the first of two bathroom ceiling lights finally went out. Carefully check the base, because the first one I bought had the wrong pin count, but this one was a perfect replacement. I was concerned at first, because only 2 of 4 bulbs lit up. However, checking the other bathroom, they all lit, and retrying in the 1st bathroom, they all did work. Probably a seating issue. Sometimes it seems to flicker a bit, but maybe I need to reseat it again. I was hoping to replace with an LED equivalent, but as far as I can see, they don't exist yet, or are much more expensive.

poor quality
bulbs blinked on and off every time we turned them on - bubbled and crackled - ultimately decided to replace with LED versions - wish had done that in the first place

Good value and works great!
These work great but I ordered the wrong color. The one I ordered is too white but still looks great!

Flickering!
The last box of these I bought were fine. But out of this box, the 3 I've used so far all flicker - some right when you turn them on, sometimes after they've been on and working fine for a while. Missed the return window since I buy bulbs before I need them so I have them on hand. This company should send me a replacement box!

Petit tube fluorescent
Ces tubes fluorescent ne sont pas très facile à trouver et fût très content de les trouver sur Amazon.Ces tubes vont dans une lampe-loupe et l'éclairage est excellent.Très recommandé.

Dañados
Desafortunadamente 2 focos venían dañados uno fundió y el otro desarmado, no los cambie, porque los otros 2 los tuve que ocupar.
