Impressed with color temp and lumens.
Made the common mistake of trying to save money and ordering cheaper leds previously. They just aren't worth it and RARELY last the test of time and fail within months. I speak from first-hand experience.
I can't speak for the durability of these yet... but if it is anything like "you get what you pay for", I shouldn't have to worry. My only concern is prolonged heat as the higher lumens bulbs emulate more, and the bulb is housed in a very small, air-tight and these type of lights are typically on for long periods of time as compared with brake lights for example, that light for shorter durations with the bulb able to cool down more. We'll see.
