The GembaRed RedOrb bulb offers the ultimate deep-red light for ambient lighting. While deep-red 660nm is naturally very dim, we use the innovative high-powered corn-cob style to deliver sufficient power in a convenient size format.

We wanted an alternative to the "blue blocking" red light bulbs that we were concerned could leak some blue light! We use a true 660nm red diode technology so it is impossible for this lamp to produce blue light and our 3rd party lab test confirmed it.

As well our 3rd party lab professionally measured the flicker, as opposed to some brands that only claim to be "no flicker" with an inadequate slow-motion video check.

The GembaRed RedOrb is an extremely pleasant red light that when used as part of a healthy lifestyle of reducing blue light exposure at night can support healthy sleep and melatonin production.
