In Israel i saw in ACE store no name CFLs branded "SPARKLE LIGHTING". They are a piece of junk for several reasons because: The factory hidden behind this brand name wrote itself a very low lamp life of just 1000 hrs (!). The CFLs tube is coated in a daylight halophosphate (Not triphosphors, just the old phosphors from the old T12 lamps!) which result is catastrophic lumen depreciation because it is much blackens even in optimium operating conditions (ie open fixture, base down etc...). Also these lamps (And another similar junks) tend to reach to mercury starving mode probably even much faster then the Philips ALTO fluorescent. I think this is a manufacturing defect and not intended manufacturing process like the Philips ALTO fluorescent. Because of these reasons i actually saw halophosphate CFL that produces no light at all when they initally switched on and only after ~30 sec they actually start to show a marks of lighting at the tube ends when the mercury start to vaporise. This is because the phosphor blocks all the light of the buffer gas.
