The "G4 12 high-power SMD LED" is significantly brighter than the lamp with 10 LEDs.
The installation is a little more fummlig, I have the plastic spacers on the pin contacts away (simply pull off) and then cut the contacts to 3mm - rebuilt they fit the bill perfectly.
A star I must deduct, since the light of this, and also the lamp with 10 LEDs, is not homogeneous white - on a white wall you can see bluish and yellowish stains.
Probably can not afford uniform enough the currently applied to the SMD-LEDs yellow filter.
Conclusion: A great product - instead of 6 x 20 watts now I need 6 x 2.4 Watt. Strong buy recommendation!
