Product Notes:
This is a near infrared/ red light/ heat bulb. It is not a decorator bulb. This TheraBulb includes a double reflective red coat and may show minor cosmetic blemishes on the surface of the bulb including: small dimples, bubbles, small spots of darker or lighter color, small marks on bulb, or color variation. These conditions may be more apparent when the bulb is on, but are unrelated to the wavelengths that are produced by the bulb and do not negatively impact its performance. All near infrared, red light, and heat output is produced by the filament that is inside the bulb.
