Made in Spain
Back to Essentials, by Denisse Clyton, is a brand of certified circadian light bulbs. We designed scientifically based lighting —spectrum measured in the laboratory, without blue light— so that the light in the last hours of the day does not interfere with the natural production of melatonin.
Each bulb has a verified Spectrum Test Report and CE and RoHS certification.

​Mission

To help ensure that the last hours of the day don't steal hours of sleep from the first. We designed scientifically based lighting so your body receives the right signal: it's nighttime, rest.

​Vision

That no home, hotel, or wellness center in Spain should have to choose between good viewing and good sleep. To be the benchmark in certified circadian lighting in the Spanish market.

​Values

Every claim we make is backed by a lab Spectrum Test Report, not marketing. If we can't measure it, we don't say it.

​Back to basics — Less noise, less artifice. We design products that do one thing and do it well: respect your biology.

​Transparency — Open CE and RoHS certifications, lab data available to anyone who asks, no fine print.
