I received a pack of two 4100K lightbulbs. I thought everything was fine until I looked at the light emitted. One emitted pink light at 4100K and the other blue-white light at what appeared to be 5000K. Both lamps are labeled 4100K, which is incorrect. Also, they don't turn on instantly, they take about 20 seconds to warm up to full brightness. So I put my 4100K LED bulbs back in until I figured it out.
