Frequently Asked Questions about Norb® Products

Goodness no; you can have lighting products with equal color temperatures that radiate different light frequencies. The light components of the NorbSmile are designed to enhance your overall well-being and to look “normal” with nearly perfect color rendering.

No; high intensity “happy lights” are therapeutic lighting products of relatively high intensity, with very specific usage instructions. The NorbSMILE is a sunlike-spectrum light—but of much lower intensity, designed for regular day to day use—in home or business, from morning until early evening. The spectrum is natural, unlike most lighting products which emit light spectra very different than the sun (and can cause people to feel lethargic, distracted or agitated).

There are four consideratons:

  1. It is a 2-pin tube (which is by far the most common type).
  2. It replaces 48” florescent tubes.
  3. It is a “hybrid” type”, which means it will work with most ballasted and non-ballasted fixtures (download a complete list of compatible ballasts).
  4. It is UL approved as a T8 (T8 means 1-inch diameter tube). It may also be used in T10 and T12 fixtures (which accommodate 1.25” and 1.5“ diameter bulbs respectively), provided a UL rating for T10 or T12  is not required (by fixture or user).

No; we specifically designed NorbSMILE to imitate the sunlight’s natural spectrum with the exception of the ultra-violet (UV) frequencies.  UV rays are what helps our body to produce vitamin D, but are also a source of radiation and thus may damage skin.

Norb bulbs are only for use on 120 Volt, 60 Hz circuits.

No; if you read in bed, just turn it off when you feel yourself becoming drowsy.

Goodness no; you can have lighting products with equal color temperatures that radiate different light frequencies. The light components of the NorbSLEEP are designed to enhance your ability to sleep and to look “normal” with nearly perfect color rendering.

Yes, this bulb will fit into E26/E27 sockets—typically referred to as a “medium” or “standard” base. This is the most common size in which you’ll find lamps and fixtures.

A PAR38 bulb is 4.75″ wide, so ensure that hooded fixtures—as are typical in track lighting cans—have sufficiently large openings to fit the bulb. It’s best to check the fixture specifications to see if it is recommended for a PAR38 bulb.

Plants need a dark period to rest and prevent metabolic fatigue. Therefore, grow lights should only be run 12-15 hours maximum per day—typically from 7 AM to 8 or 9 PM (to mimic light conditions in tropical regions). The rest of the time, they should be in darkness, or near darkness.

Do not light your plants with NorbBOTANIC for more than 15 hours per day.
