Daylight at night!,
Verified Purchase(What is this?)
This review is from: Cool White 35w Energy Saving Spiral Light Bulb, 175w Equivalent Very Bright, Bayonet Cap B22, New Advanced T3 Technology Instant Light
Love these lamps. Very bright. They do seem to take a few short seconds to get to full brightness, but still bright enough when switched on. I've bought 5 now. Sadly, I dropped and broke one :-(
The first one I got emits a fairly high level hum (not loud) for couple of minutes on switching on, but that's the only issue I've noticed with them. The others seem to be silent. Nice bright white light = happy customer. Only time will tell regarding their lifespan.
Addendum: I've been using these lamps for a while now, and just wanted to add that the lamp that emitted a hum didn't last very long. All the others I'm using are working fine, with no funny noises.
