What’s the difference between incandescent and LED red light therapy?Updated 9 hours ago

Incandescent (like our FireLight® Bulb): Our bulbs emit broad-spectrum, polychromatic light spanning 550–3000+ nm. That includes visible red, full-spectrum near-infrared (700–1500nm), mid-infrared, and even a touch of far-infrared. You get therapeutic warmth plus deeply penetrating wavelengths that stimulate circulation, mitochondrial function, and systemic detox.

FireLight® Bulbs offer 2–4x the irradiance in the photobiomodulation range (600–1000nm) compared to typical incandescent heat lamps, and they’re naturally flicker-free.

LEDs: LEDs emit narrow-band light using small diodes, usually without heat or the full NIR spectrum. They tend to flicker, which can cause subtle neurological stress over time. While LEDs may last longer, they gradually dim, reducing their effectiveness over time.

Bottom line: Light therapy effectiveness depends on irradiance, spectrum, and fluence (total dose). Incandescent therapy provides fuller, deeper healing with warmth your biology craves. LEDs have their place, but when it comes to regenerative light? Nothing compares to incandescent.
