these U-tubes are worth a look.
Each "reviewer" gives their impressions and many details about recently available (in the USA) Philips LED bulbs that are a good approximations to CFLs.
The 28+ year life claim is rather dubious while the prohibition against use in sealed or hot environments needs to be taken seriously.
Wonder when they will show up at Woollies .........

I wonder whether they're misrepresenting the MTBF as being the average life. This bulb appears to be derived from (or is indeed identical to) the Ambient Light, which contains electrolytic capacitors. Expecting
25,000 hours average life seems excessively optimistic.I note that they're offering a 6 year warranty (based on "up to" 3 hours usage per day - does that mean no warranty for any period if you run it
4 hours a day?). They may be assuming (probably rightly) that few people would bother to make a claim even if the bulb failed sooner.Sylvia.
** The figure is the estimated, continuous life of the LED chips used.
** Good quality electros will easily do that many hours, as it is less than 3 years.
But not if they get too hot.
** CFLs are often used as night lights in buildings and homes, running up to 14 hours per day.This exceeds the 25,000 hour figure in 5 years, so has to be excluded.
The 28 years life figure is dubious for many other reasons.
