A faint red glow is visible when it's on, which is normal and indicates it's working at peak performance. It's the ideal, cost-effective choice for maximum clarity in most home and business security setups. For Total Stealth (940nm): If you require complete invisibility with zero visible glow for covert operations, an 850nm bulb is not the right choice. For a 100% invisible no-glow illuminator, please search for our 940nm version on Amazon using the ASIN below. 🔍 Looking for a Completely Invisible IR Bulb?
