DESCRIPTION

NorbSMILE SOFT is a premium full spectrum light bulb with a Sunlike™ 4000K design, created to bring the natural quality of sunlight indoors with a softer, gentler tone than the original NorbSMILE. At 4000K, it contains slightly less blue and more red in the spectrum, creating a balanced daylight feel that is bright yet comfortable.

People respond physiologically to light, yet the average person spends 93% of their time indoors under artificial lighting that often lacks the spectral balance of natural sunlight. Standard bulbs can leave spaces feeling flat or overly harsh—especially during darker winter months.

NorbSMILE SOFT is designed to mimic the visible spectrum of sunshine (without UV radiation), delivering clear, vibrant illumination with a gentler tone than a 5000K bulb. Its full spectrum LED design supports natural-looking color and comfortable everyday lighting.

Ideal for offices, kitchens, desk lamps, hallways, foyers, workout rooms, bathrooms, hotel rooms, and conference spaces where you want bright but not overly cool daylight.

FAQs

Have questions? Norbie has answers.

What makes NorbSMILE SOFT different from a regular LED bulb?

NorbSMILE SOFT uses a Sunlike™ full-spectrum 4000K design that more closely resembles natural, softer daylight than standard LEDs. Unlike typical bulbs that focus primarily on brightness or color temperature, it is engineered around spectral balance and visual comfort.

With a high CRI of 96, NorbSMILE SOFT renders colors naturally and accurately while providing the softer, more comfortable quality of light many people want from full spectrum lighting.

Can NorbSMILE SOFT help with winter blues or Seasonal Affective Disorder (SAD)?

NorbSMILE SOFT provides bright, sunlike indoor lighting that many people prefer during darker months. Its 4000K full spectrum illumination provides everyday daylight-style lighting throughout your home or workspace.

While NorbSMILE SOFT is not a medical device or a replacement for a 10,000-lux SAD therapy light, it can provide natural-looking ambient lighting during the day.

Does NorbSMILE SOFT produce UV light or vitamin D?

No. NorbSMILE SOFT does not emit ultraviolet (UV) light and does not stimulate vitamin D production. It mimics the visible portion of natural daylight while excluding UV wavelengths.

Is NorbSMILE SOFT safe for eyes? Does it flicker?

NorbSMILE SOFT is UV-free and engineered to minimize flicker, which can improve visual comfort compared to lower-quality LED bulbs. Like any light source, it is intended for ambient lighting and should not be stared into directly.

Can NorbSMILE SOFT replace my regular light bulbs?

Yes. NorbSMILE SOFT is designed as an everyday full spectrum LED light bulb for living rooms, kitchens, bathrooms, bedrooms, home offices, and workspaces.

It features a standard A19 shape with an E26 base and fits most common fixtures. It is dimmable and operates on standard 120V, 60Hz circuits.

If your fixture requires a recessed or track bulb, choose the PAR30 version instead.

What’s the difference between NorbSMILE SOFT and the other NorbSMILE bulbs?

NorbSMILE SOFT is 4000K, offering a slightly warmer, gentler daylight tone compared to the original NorbSMILE (5000K), which delivers a brighter, crisper light for maximum alertness and high-focus environments. The A19 11W (5000K) provides 800+ lumens in a standard lamp shape, the A19 9W (5000K) offers 720+ lumens with slightly lower brightness and added energy efficiency, and the PAR30 (5000K) delivers 750 lumens in a directional reflector design for recessed and track lighting.

All models are CRI 96, UV-free, dimmable, energy efficient and designed for daytime use — the primary differences are tone, brightness, and bulb shape.

What does “SOFT” mean in NorbSMILE SOFT?

SOFT refers to the 4000K color temperature, which provides a gentler, slightly warmer daylight tone than the original 5000K NorbSMILE.

NorbSMILE SOFT maintains the full spectrum, Sunlike™ design and CRI 96 of the NorbSMILE line while offering a softer hue for spaces where you want natural daylight without an especially crisp or cool appearance.

Is NorbSMILE SOFT a full spectrum light bulb?

Yes. NorbSMILE SOFT is a full spectrum light bulb with a 4000K Sunlike™ spectrum designed to replicate the visible qualities of natural daylight without UV radiation.

Its softer 4000K tone provides a gentler alternative to the brighter 5000K NorbSMILE while maintaining a high CRI of 96 for natural-looking color.
