I love the color rendering and lumens per watt but now 2 lamps of this type are showing the same performance issue. After a short period of use, the lamps are dimmed after one to two minutes and get brighter again after another 5 minutes. This is not due to "warming up", but to problems with the electronics in the lamp. In the first few months of service this was not the case. Honestly it's annoying and if the lightbulb didn't cost so much I would replace it now. I'll wait for him to die and find another guy.
