But these bulbs have a big problem:
They flicker! And regardless of whether they are operated on a dimmer or directly into a luminaire with ordinary switch. It is perhaps not notice any immediate - like the time was also in CRT monitors, depending on the Hz-number it have some more and others less noticed. I already have various GU10 LEDs in use - but only at the luminea LEDs I noticed a flicker.
The problem of flickering LEDs is also described, for example here:

At least on my Dimmer (Busch-Jaeger 6593U) could I the luminea LEDs felt only about 70 to 60% of their maximum brightness dimming down -. That was still blinding Because this dimmer I have a high "minimum burden" required for the Extra simultaneously dimming test two 50W halogen spotlights used (lamp with 4 lamps, 2x + 2x 50W halogen luminea LED). Possibly But does it work in other dimmers dimming better, I do not know.
The light color is despite "warm white" still significantly cooler than halogen.
These lamps remain lit for ever, even though you have turned it.
The color rendering of the LEDs are given luminea with 70Ra. Improved LEDs have a minimum 80Ra and this value is required (as a minimum) since 2013, the EU also for lamps indoors! Light bulbs are about 100RA. These values represent the quality of the color rendering of light sources. The higher the value the better. At low values, it may be that one color is not as usual perceives and as food / no longer look unnaturally so fresh.
Note should also interested the angle:
Halogen lamps usually have only 30-35 °, some perhaps even 50 °. This LED spot of luminea other hand, has 120 °. For small closets or other rooms to be possible completely illuminated certainly an advantage in the living room but the game of lighter and darker areas and a more targeted lighting example of murals makes usually just better.
