Customer Review: when they work they are great!
Summary: 3 Stars
My 4 pack arrived yesterday and one was broken in the box with no signs of damage to either of the two boxes (inner and outer) they were shipped in so it had to happen at the factory. Out of the remaining three, two work fine. They are BIG and bright. But the fourth has such a loud hum that you can hear it from 10+ feet away. So for the price I am not very happy. Sine Amazon won't replace this bad set I had to order a new set and these are being returned for a refund. Hopefully they will all be in one piece and will not hum but I don't have high hopes. Also one of the remaining two has a something in the base housing that you can hear moving around. The light works and doesn't hum but still these don't seem to be built well.Customer Review: Expected them to be brighter
Summary: 3 Stars
I bought these bulbs expecting some serious light output. To look at the size of them, you'd think they were bright as the sun. But the light they put out is just as bright as a normal bulb- maybe even a little dimmer! The white is very balanced and neutral, but to say these could be used for photography or SAD is a huge stretch of the imagination. Worth half of what they cost.Customer Review: They make buzzing sound
Summary: 3 Stars
They are excellent bulbs except they make a buzzing sound. I could not read with them, so I returned them.Customer Review: Fantastic light but emits a very loud hum
Summary: 2 Stars
These bulbs do a great lighting job and I'm still using them -- but in places where I don't have to be near the bulb (like in ceiling fan lights). I initially tried these in the bathroom but the buzzing was intense. I thought it might be the socket (although it never had problems before) so I tried other fixtures (admittedly only tested two of the four bulbs so far). Every one of them emits a terrible humming that, if it is in your ear's "line of sight" (like in a desk lamp or a vanity) then it will drive you mad.Customer Review: Rare side-affects
Summary: 2 Stars
I agree that the product emits a good white light and has a higher brilliance than normal bulbs. However, it can cause mania in people who have a family history of bi-polar disorder or depression. It can also cause the 'crash' associated with the end of mania. I advise caution and careful, reflective self-monitoring when using this product.
