I am very pleased with the LED spotlights. Is bright and emits a beautiful light - not too cold and not too warm. With a total length of 3 meters I installed 8 spotlights, so on average every 40 cm and have thus replaced the existing FL tubes. Maintain a flicker like others I have not found until now (several months in use).
The only complaint is the somewhat lame tension spring. So the hole drill rather smaller than indicated. But even then, the radiator sits rather loosely as fixed in the opening.
