But in this day and age are LED bulbs currently:
After the purchase I have the lamp with LED bulbs fitted (model Samsung LED Classic, 810 lumens, 10.8W, E27 base).
They are only minimally larger than those provided for light bulbs (R63 spotlight), but fit perfectly into the base (before buying, I was not sure, in particular due to the long metal versions of the lamp). Do not stand in front and you can see them so can not say that they are different. ;-)
In addition, I rebuilt the lamp so that I can now turn each one, or two bulbs separately (for someone with a little technical understanding is that no problem at all and is done in a few minutes).
Result? A beautiful, energy-saving lamp with bright spotlights. I am very satisfied and have rebuilt even bought the 2-way bar the same manufacturer and, as described above.
