NorbSMILE SOFT s a unique white light with a specialized Sunlike™ spectrum designed to lift your spirits and boost your energy — with a warmer, softer hue than 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. Standard bulbs often lack the spectral balance of natural sunlight, which can leave us feeling sluggish or drained — especially during darker winter months.
NorbSMILE SOFT is designed to mimic the visible spectrum of sunshine (without UV radiation), delivering clear, vibrant illumination that supports energy, mood, and healthy daytime alertness, with a gentler tone than a 5000K bulb.
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.

Frequently Asked Questions
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 only on brightness or color temperature, NorbSMILE is engineered around spectral balance and visual comfort. With a high CRI of 96, it renders colors naturally and accurately.

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. While it is not a medical device or a replacement for a 10,000 lux SAD light therapy box, it offers everyday ambient daylight-style illumination throughout your home or workspace.
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. It is designed for normal ambient use and should not be stared into directly, like any light source.
Can NorbSMILE SOFT replace my regular light bulbs?
Yes. NorbSMILE SOFT is designed for everyday use in living rooms, kitchens, bathrooms, 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 recessed or track lighting, choose the NorbSMILE PAR30 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.
• A19 11W (5000K): 800+ lumens in a standard lamp shape.
• A19 9W (5000K): 720+ lumens with slightly lower brightness and added energy efficiency.
• PAR30 (5000K): 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.
