LED lighting is both better and worse.
- purposefully made with line frequency (60hz) refresh which means its actually constantly blinking. you can see this with led Christmas lights by moving them.
- pack liquid capacitors designed to fail well before the rest of the board.
- thermals are too hot and fry the diodes or the rectifier IC’s.
- wrong colors sold everywhere. a proper 4000K 90+ CRI led is hard to find and more expensive. the two most often available are 2700K (yellow) and 5000K (blue)
- adgjlsfhk1 2y agoWhy do you want 4000K? Incandescent/halogen are 2700k/3000k, and sunlight is 5000k. 4000k is flourescent, and I don't think anyone wants lighting to look like that. That said, if that's what you want Lowes has it (technically 3500k at CRI 90) https://www.lowes.com/pd/GE-Pro-60-Watt-EQ-A19-Bright-White-Medium-Base-E-26-Dimmable-LED-Light-Bulb-16-Pack/5013821257 https://www.lowes.com/pd/GE-Pro-60-Watt-EQ-A19-Bright-White-... Also, only the absolute cheapest LEDs have noticeable flicker. Decent ones have big enough capacitors to make it un-noticable.
