Cozion 150W Infrared Lamp Review. More Info and Purchase: Buy Me A Coffee: Blog: After a fall a while ago I started developing arthritis in my hand. I found that a red light LED therapy pen helped the swelling and inflammation to go down very quickly and I became a fan of the technology and since then have bought a redlight panel for general health benefits. I was interested to try this red light lamp, or heat lamp as we used to call them, as it uses an incandescent bulb rather than the newer LED technology. So what are the differences? The LED devices offer a more tightly focused light wavelength, usually 630, 660 and 850nm whereas the incandescent bulbs give out a much wider spectrum of light from near infrared to visible light. Also, the LED devices generate very little heat compared to the bulbs
