I had / 35W halogen spotlights exchanged my 20 against the "MR16 GU 5.3 LED bulb light 280LM Spot Light 3W 3200K Warm White" here from Amazon. This cost exactly half of the above radiators. After replacing the living room we were quickly dissatisfied because they did not bring the power of the old halogen spot. So I went again in search of something better. I've found then the 5W emitters. Processing is TOP. The light output I would assign exactly the 35W halogen spotlights. Maybe even a little brighter. The light color is just right. Now we can only hope that even the durability of the lamps fits .....
