They are a little darker than the origin-40W lamps and a little direction bound (small cone), with lamps for lighting with three or more spotlights no problem. With only two spotlights these LED lamps are suitable only for "Effektrbeleuchtung", in the room it would rather dark.
The lamps light up after being switched off for something, but that's not distracting. It was important for us immediate brightness!
Conclusion (for us):
- Bright enough (not very "40W")
- From three lamps in the luminaire OK for rooms Lighting
- Immediately light
- Light afterglow
- Good value for money (brand products usually 200% more expensive)
