Frequently Asked Questions about Norb® Products

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).  When unsure, hire an electrician to bypass the ballast (see our wiring diagram).
  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.

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.

We recommend that you request the services of a professional electrician before proceeding.

Before getting started, always disconnect all power (at the circuit breaker) to ensure that no electric current is flowing to the fixture.

Show the wiring diagram below to your electrician.  Note: it does not matter if the live wire was on the left or right side of the fixture as long as the other end is neutral.

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).

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.

Researchers have found that narrow green light use on a regular basis may reduce the incidence of light-induced migraines. Once a migraine has started, green light has been shown to reduce pain.  Some users of NorbRELIEF have indicated that it enables them to work and read with a migraine.

Yes—it may seem a bit weird, but it’s completely normal.  Purple is the opposite color of green for the human visual system.  Our retina contain red, blue and green color photoreceptors.  The green cones become saturated by the green light of NorbRELIEF, so momentarily only the combination of red and blue cones are able to be activated until the pigments get recycled by the green photoreceptor cones.  It only takes a few minutes for this to go back to normal for most people (without retinal disease).

Yes!  At 800 lumens, NorbRELIEF is bright enough to read with.

In the photo below, the page looks very green as the camera captures the full saturation of green color.  Human vision is a bit different.  After a very brief adjustment, the page will appear whiter and the contrast between the page and the text will be stronger.

NorbFOCUS contains a spectrum of light that researchers have found correlates with faster reading, better recall and retention.  It is not a substitute for prescribed treatment of any illness or disorder, including ADHD.

NorbFOCUS assists with faster reading speed, better recall and retention; however, proper sleep is also crucial to mental performance.  Because NorbFOCUS inhibits melatonin production, it is not recommended for use within a couple of hours of bed time.  During those hours, we recommend winding down for a good night’s sleep with NorbSLEEP.

NorbBUG LITE is not a bug repellent (no light is).  It reduces the number of insects in a space as it leaves out the light spectrum that draws them in.

Ordinary bulbs include light colors that attract insects. You may still see a few bugs when using your NorbBUG LITE, but you should see far fewer of these pesky invaders compared to other light bulbs.

We developed two options for NorbBOTANIC PAR38 in response to a need for even lighting across a vertical garden surface (through our sister company, LiveWall).

A wide beam angle spreads the light out horizontally but not as far vertically from the lamp. A narrow beam angle allows the light to travel further.   Thus, we use the 30 degree beam angle bulbs  to light the upper rows of a living wall and the 15 degree beam angle bulbs are used to light the lower rows of plants.

The same priniciples apply to how far your plants are distanced from your lamp.  Use the wider beam angle (30 degrees) to illuminate plants that are 3′ – 5′ from the lamp.  Use the narrower beam angle (15 degrees) in fixtures mounted 5′ – 10′ from the plant canopy.

Use the 30 degree beam angle to illuminate plants that are 3 to 5 feet from the lamp. Use the 15 degree beam angle to light plants that are 5 to 10 feet from the lamp.

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.

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