Question: how many hours of life are guaranteed
Document: Very high output light bulbs. It amazed me how bright they were for how small it is. You will save money using these and you won't be in darkness again.I also like how many bulbs are included so you can have replacements for way far in the future because these won't wear out for a long time.
Out ceiling fixtures have a narrow throat that these bulbs must fir through. With redesign to meet new efficiency standards many bulbs are a bit to large in diameter to fit easily into our fixtures. These bulbs fit  and the price was right. Just the combination for us.
The lifespan is far shorter than advertised. Of the bulbs I purchased, more than 30% have died after less than a few hundred hours of use. I would avoid these bulbs in the future.
good deal and they work! Not much else I am looking for in a light bulb. I would buy from again.
Very much appreciate being able to purchase this type of light bulb in quantity at an affordable price. It arrived promptly and was packed with care. Will be ordering this again when needed.
This lightbulb has a really long lifespan of the light which is good and the good thing is so bright which can lighten up a big area of your house or outside. I love how it doesnt cost much and it give 6 out. I would recommend to buy this item.
They are every bit as good as any of the manufacturers I was more familiar with. I liked buying more than one at a time and am saving this link!
These lights fit in our ceiling fan and provide plenty of light when we need it. And they are efficient and affordable too.
These bulbs burn out way before they should. I have already replaced three within the last 6 months. I think I should get replacement bulbs free of charge.
The positive reviews are lies. Look at their review history. It is the seller trying to bury bad reviews with fake reviews. Amazon should ban this seller.I bought 6 and put 2 in. One burned out and the other shattered in the socket after a couple of months when I only used them a few times per week. No way am I using any of the others.
Answer: yes
