The reason why LED lights use blue emitters is because phosphor crystal and/or quantum dot crystals can be layered on top to transform a portion of blue light into the longer wavelength cyan, green, yellow, orange, and red wavelengths. Cheap LED lights use only yellow phosphor to mimic a certain color temperature so steer away from any LED bulbs that are rated below 90 CRI (Color Rendering Index, 100 = incandescent). For reasonable cost per bulb, I am very fond of the Sylvania TruWave bulbs as they use a blue emitter that produces multiple wavelengths of blue at 50% less intensity of normal single wavelength blue emitters and much more closely follow the true black body emission spectrum of incandescent bulbs. However, if you want the best LED bulbs, then I recommend 95+ CRI bulbs that are additionally rated 95+ R9 (R9 is a specific test of a bulbs ability to render deep red color). The Soraa Vivid series of bulbs are some of the best I’ve seen that are readily available and use violet emitters instead of blue emitters and instead add a blue phosphor to the top layer to precisely control blue output. Their light output truly recreates the old school incandescent 2700k bulbs, or 3000k halogen/tungsten bulbs faithfully depending on if you opt for their 2700k or 3000k offerings. If you are looking for a night time bulb that does not produce any blue light, then the Soraa Zeroblue series is the best out there. It is the only no blue output bulbs that still render colors correctly and maintain a true incandescent 2700k color temperature by using a violet emitter and omitting the blue phosphor. If you look at the spectrograph for the Soraa ZeroBlue series, you will notice that the range of blue light that interferes with circadian rhythm (440-490nm) is completely missing. However you will pay an arm and a leg for each bulb.When will we see red LED technology so we can stop ruining our eye health? With LED technology replacing most indoor lighting our exposure to a one sided light spectrum all day long (unless you take more frequent breaks outdoors for real sunlight exposure) is literally ruining most people's eyesight over time.

Blue LEDs are fine at a lower more comfortable CCT. They can replicate incandescent light if that’s your thing or they can just give you really good color rendering at a more comfortable CCT like 3500k-4000k.When will we see red LED technology so we can stop ruining our eye health?

No problem, I’m a huge LED geek. I make custom flashlights using raw LED emitters.Very good info. The bulbs in my office and work area are Sylvania TruWave which I really like. I didn't know about the Soraa bulbs so I will have to check those out. Thanks.
