Soraa ZeroBlue LED Bulbs

How ZeroBlue Works (and Why It's Not Just Another Warm Bulb)

Artificial light at night is loaded with blue wavelengths, and blue is the part of the spectrum that suppresses melatonin and signals the body that it is daytime. That is the problem ZeroBlue is built to solve. Where a standard warm bulb only dims the blue, Soraa ZeroBlue is engineered to remove it almost entirely - Soraa rates it at less than 2% blue wavelengths and about 40% fewer melanopic lumens than conventional LEDs - while still producing a true 2700K soft white with no amber tint or yellow cast. It comes in A19 at 600 lumens and BR30 at 700 lumens, both 120V on an E26 medium base, and both dimmable.

Standard Warm LEDs Only Reduce Blue

A standard warm LED reaches 2200K or 2700K by shifting its spectrum toward amber. The blue is still there, just less dominant, so your eyes read the light as warm while your circadian system still detects the blue signal behind it. That is why a warm-white bulb can look cozy and still leave you alert at bedtime - the color temperature changed, but the blue did not go away.

How ZeroBlue Removes Blue With Violet LEDs

ZeroBlue takes a different path. Instead of a blue LED behind a phosphor, it uses violet LEDs with custom phosphors that skip the blue range entirely, leaving a physical gap in the blue part of the spectrum. The result is a clean 2700K white with almost no blue for the circadian system to detect, which is how Soraa designs it to let the body's natural melatonin production stay on track through the evening. It is the difference between masking blue and actually leaving it out.

True 2700K White, Not a Yellow Tint

Amber sleep bulbs address the blue problem by turning the light yellow, which washes out colors and makes a room look dim and dated. ZeroBlue does not. It holds a manufacturer-rated 80 CRI with R9 90, so skin tones, fabrics, wood, and decor still read naturally under it. You get the circadian benefit of a blue-free spectrum without the yellow cast that usually comes with it, which is what makes ZeroBlue practical to live and work under all evening rather than only in the last minutes before bed.

Where to Use ZeroBlue

ZeroBlue earns its place in any space used in the evening or overnight, where blue-heavy light works against the people in it. For the full effect, Soraa suggests running it in the two to three hours before bed. Here is where it fits by room and by property type:

Bedrooms, Nurseries, and Living Spaces

At home, the bedroom and nursery are the first places to switch - swap every lamp and overhead fixture so the last hours before sleep are blue-free for both adults and children. Living rooms and dens come next, since they are the evening spaces where people unwind before bed. Because ZeroBlue keeps colors looking natural, it works in these everyday rooms without making them feel like a darkroom or forcing a yellow glow on the whole space.

Hotels and Hospitality

In hospitality, ZeroBlue goes in guest rooms, spa areas, and lobbies that carry an evening ambiance. A guest who is not flooded with blue light late at night has a better chance at real rest, and rest is what tends to turn into good reviews and repeat stays. It is a low-touch upgrade a property can standardize across every room and fold into the guest experience, using the same shapes it already stocks for A19 lamps and BR30 cans.

Healthcare, Schools, and Offices

In healthcare, patient rooms and overnight nurse stations benefit from a spectrum that supports patient rest without fighting the body's clock. Schools and offices use ZeroBlue in evening-shift and after-hours areas, where people need bright, alerting light during the day but wind-down cues at night. Anywhere a building runs into the evening, matching the light to the time of day is the goal, and ZeroBlue is the bulb built for the night end of that range while daytime spaces stay on brighter, higher-CRI lines.

A19 and BR30 Options

ZeroBlue comes in two shapes on the same E26 base, so one blue-free spectrum can cover lamps and recessed cans alike.

ZeroBlue A19 (11W / 600 lm) - the standard screw-in shape for table lamps, floor lamps, and enclosed ceiling globes, with omni-directional light.

ZeroBlue BR30 (15W / 700 lm) - the reflector shape for recessed cans and downlights, with a focused 120-degree beam and brighter overhead output.

A19 or BR30 - Which Shape Do You Need?

Both shapes deliver the same blue-free 2700K light, so the choice is only about the fixture and how you want the light to spread.

A19 for Lamps and General Fixtures

The ZeroBlue A19 is the standard screw-in bulb shape at 11W and 600 lumens. It fits table lamps, floor lamps, ceiling fixtures, and enclosed globes, and it sends light in every direction for even, all-around illumination. If you are replacing an ordinary household bulb in a lamp or a covered fixture, the A19 is the one to reach for.

BR30 for Recessed Cans and Downlights

The ZeroBlue BR30 is a reflector shape at 15W and 700 lumens, made for recessed cans and downlights. Its focused 120-degree beam pushes light downward, and the higher output suits overhead installations where you want a defined pool of light rather than an all-around glow. For ceiling cans in a bedroom, hallway, or hotel room, the BR30 is the match.

Matching Both Across One Property

Many installs use both - A19 in the lamps and fixtures, BR30 in the recessed cans - so an entire home, floor, or guest room runs on the same blue-free spectrum. Both share the E26 base and 120V supply, both are dimmable on trailing-edge and phase-cut controls, and both are enclosed-fixture and damp-location rated, so a single order can cover every socket in the room without a special-order part.
