This review is from: Daylight Energy Saving Spiral Helix Light Bulb 30W BC 640 Prolite 30 Watt (Kitchen & Home)
Another cheap CFL lamp claiming to be something it is not. Gives a flickering start and very slow to warm up. However, once it has got going the light frequency output is pretty good, but don't expect it to last long before it fails. Six months maximum. An expensive bulb indeed for something that will not last.
