Well - something was bound to be messy, with this offer.
Would otherwise be far too low.
Otherwise, the only time things are OK
I feel the brightness as well.
The big question is, of course,
how long they will keep (1 year? 4 years?)
and how much the brightness decreases (10%, 25% ...).
Ingesamgt those things are a bit more efficient than
Energy-saving lamps, but currently more expensive.
Everything else will tell.
