Red LEDs vs Yellow Incandescents (2700K)
Red LEDs look like the perfect solution..
But are they really?
Let's talk about it..
Red LED (~620-635 nm) basically has ZERO blue.
Incandescent (2700K) follows Nature’s blackbody spectrum. Its small amount of blue is naturally balanced by a huge amount of red & infrared (IR).
At lower brightness (using dimming via variac transformer/resistor-based dimmer), the blue component can shrink even more.
Standard Red LED → No Infrared
2700K Incandescent → Emits Infrared
Standard Red LED → High Flicker (PWM & Driver-Induced)
2700K Incandescent → Minimal Flicker due to thermal inertia
Standard Red LED → Generates a lot of Dirty Electricity
2700K Incandescent → No Dirty electricity
Standard Red LED → Artificial Narrow spectrum light
2700K Incandescent → Full spectrum light
The human brain and skin require heat (infrared) to accompany light. That rules out everything but the Sun, Fire and Incandescent light.
Choose wisely.
