If people feel good, a lot of good things can happen.  It's a fact that light not only influences our immune system but also our state of mind, general health, & our wellbeing. Using Full Spectrum light, a lack of concentration due to ill-lit rooms can always be counterbalanced: Eyestrain, headaches & fatigue can be kept at bay by minimizing the otherwise adverse effects of light.  Stress, aggressiveness, hyperactivity & difficulty in learning are not uncommon due to flickering & bad lighting, which triggers off a permanent stress in humans who then are often wrongly diagnosed .



DO YOU - HAVE GLAUCOMA or CATARACTS, PUT ON MAKEUP, READ or STUDY, SEW, KNIT, CROCHET, SCRAPBOOK, PAINT, DESIGN, CRAFT, WOODWORK, CARVE, use CALIGRAPHY or a KEYBOARD, or do any number of activities where light is essential to carry out your activity?  THEN YOU should at least consider  looking into 'FULL SPECTRUM' lighting. 


The desk/task lamps are convenient in many settings.  We're sold out of the cfl's, except for the 11 watt, which is equivalent to a 40 watt bulb light, except that it's brighter and whiter - which makes things crisper.


The Full Spectrum CFL's, other than the above, are now sold out, & we won't be re-ordering.





      Full Spectrum lighting used to be the exclusive domain of the rich and famous. No more! With this new Technology you can treat yourself to a light that brings out the true colors in your work, reduces eye strain by making letters & words in books sharp & clear. Natural Daylight Full Spectrum lighting produces visual results plus health benefits, almost too good to be true!

Experience the pleasurable, visually calming, lighting of 'full spectrum' bulbs.  NO SQUINTING, NO HEADACHES, NO GLARE and NO YELLOWISH TINGE! 

Just precise, clean, sharpe, clear print that is soothing to your eyes, be it on the printed page, or next to your computer monitor screen, or over your keyboard. 

My experiences with Full Spectrum lighting started 18 years ago, once discovering that my 'migraines' were triggered by regular 'fluorescent' overhead lighting, which we find in most offices & often in the stores where we shop.

Full Spectrum lighting used to be the exclusive domain of the rich and famous. Unfortunately until just a few years ago, the bulbs were only available for overhead fixtures at an astranomical cost. About 550% more per 4' tube compared to the regular fluorescent tubes we're so accustomed to.  But when you suffer agonizing pain & lost work hours, sometimes any cost is worth the price if it gives relief from the suffering, lost wages, & even lost employment.  By an approximate comparison, a fluorescent tube costs perhaps $3.50 & a Full Spectrum tube $23.50. before taxes & shipping.

About 3 years ago I discovered that Full Spectrum CFL's (compact fluorescent lights) were becoming available for home use.  Desk lamps like those from Ott Lite have been around longer, and I've been using a couple of their lamps for over 6 years. 

We're offering this one style of desk lamp for about 50% less than the usual retail. This style is adjustable, has a swivel head, lighted switch, & can be compactly folded up if need be.   $ 21.77  no HST

SALE PRICE:  $19.50  no tax      for Full Spectrum Desk/Computer/Task Lamp

Studies show that 'grades' improve under natural daylight – OttLite® lighting brings the power of natural daylight indoors. The Learning Light uses a cutting-edge technology designed to provide a low heat, low glare, natural illumination which helps reduce eyestrain and create a comfortable environment for studying, reading, computer work, and close up/detail work.     


 Full Spectrum CFLs closely equivalent to 40, 60, 75 & 100 watt incandescent bulbs.

Sorry, these bulbs have been discontinued.


All Full spectrum bulbs have been discontinued. 


40-50 watt standard   - 11 watt CFL

60-70 watt standard   - 15 watt CFL

75-90 watt standard   - 20 watt CFL

100-115 w standard    - 23 watt CFL


Many people have made the change from incandescent bulbs to Fluorescent since the cost has become more affordable, knowing too they'll trim power usage. If you remember how poor the light from them was, no doubt you saw a big improvement when replacing them.

The changeover to 'Full Spectrum' is quite similar, as you're able to compare the degree of yellowish light you're now getting from regular fluorescent CFLs & the extreme clear bright 'white' of 'Full Spectrum'.  It will astonish you how much better seeing and reading is, & how the colors of everything nearby just seems to 'come alive', as if you'd brought the sun right into your home.   Prices are below:

           Regular Fluorescent bulb 

                  Full spectrum bulb 


The true color of light is defined as its "color temperature", or how the light looks in terms of white. It's measured in 'degrees Kelvin'. The higher the color temperature, the cooler or more blue the effect of the light.  Natural sunlight is the point of comparison.

The Northern Sky produces a cool blue light which would replicate 8,000 degrees kelvin.

An Overcast Sky produces a bluish light which would replicate 6,500-7,000 degrees kelvin.

Sunlight At Noon!!  is the whitest light with a kelvin temperature of 5,500 degrees.

Candle Light has a soft yellow light. This is the warmest light of 2,000 degrees kelvin.


The further you get away from 5,500 K in either direction, the further

you get away from "full spectrum" lighting.

Incandescent = 2700K

Halogen = 3000K

Warm White Fluorescent = 2700K

Cool White Fluorescent = 4100K

"Full Spectrum" Natural White = 5000K

The Truth About It

To make an incandescent bulb full spectrum, the light that it produces passes through a filter of neodymium glass(in the cheaper bulbs, just a coating), which enhances the light and brings it as close to natural sunlight as an incandescent bulb can get. If the bulb doesn't have the familiar bluish/purplish neodymium glass shell, it is NOT a full spectrum incandescent bulb. Period. The fluorescent produces light based on the phosphurs inside the bulb and needs no filter. Fluorescent full spectrum is always better than incandescent and should be your first choice. Fluorescents are much more energy efficient, and last twice as long as many so called "long life" incandescents. A lot of people advertise full spectrum fluorescent bulbs as being a treatment for depression (S.A.D.--seasonal affective disorder). A fluorescent can't even think about being helpful to S.A.D. unless it has a color temperature of 5500K - 5600K(not 5000K, not 6500K), and a C.R.I. of at least 90.  CRI means Color Rendering Index. It's a measurement of light equivalency, 0 being darkness and 100 being direct sunlight. When it meets those criteria, it becomes the most optimal full spectrum bulb available. So, while full spectrum Natural White 5000K fluorescent makes a great reading lamp and an outstanding source of beautiful natural white lighting, it's not at all helpful nor should it be used as, a treatment for those people who suffer from Seasonal Affective Disorder. These fantastic fluorescents are much closer to the color spectrum configuration of natural sunlight, than a regular standard cool white fluorescent. As a result, glare is minimized, colors are brighter and truer, and eye strain is greatly reduced. To sum it up, a fluorescent 'full spectrum' bulb is better than an incandescent, or regular fluorescents and you should always know and strongly consider the C.R.I. and Kelvin of the bulb!  For treatment of SAD, a color temperature of 5500K-5600K and a C.R.I of 90 or higher, being as close to natural sunlight as you can possibly get, would be needed.   




My light fixture is for a 75 watt bulb. Can I use a CFL equivalent to 100 watts, as long as it uses less than 75 watts of power

 If a light fixture is rated for a maximum 75 watts with an incandescent bulb, can I use a CFL that is the equivalent to a 100-watt incandescent as long as it uses less than 75 watts of power?   Yes, any bulb that does not exceed the fixture rating can be used.  The watt rating on the fixture is a description of how much electricity the internal wiring of the fixture can accept safely. A watt is a measure of power consumption. As long as you do not exceed the recommended wattage for a particular fixture, you can use any CFL wattage up to the limit. For example, if a light fixture is rated for 75 watts of power, you can use any light bulb with a rated wattage of 75 or less. While you could use a 75-watt equivalent CFL, if you want more light in this fixture, then you could use a 100-watt equivalent CFL. Most 100-watt equivalent CFLs use between 23 and 30 watts of power, much less than the 75-watt rating of the fixture. That's the great thing about CFLs you get more light for less power!


Can I use my CFL in a totally enclosed fixture?

Before using a CFL in a totally enclosed fixture, you should consult the product packaging.  CFLs that are not designed for totally enclosed fixtures will typically carry a disclaimer that indicates that they are not intended for this type of application.  Because totally enclosed fixtures do not allow air to circulate around the lamp, it causes heat to build up, which can lead to performance issues. 


Though CFLs do not produce nearly as much heat as incandescents, they are more sensitive to heat, which can effect their performance. Some of the components in a CFL can not withstand high heat, unless specifically engineered to do so. The excess heat that is created in a totally enclosed fixture can cause the light output to be diminished, the bulb to appear to "dim" more quickly than CFLs used in applications that allow airflow, and a shorter bulb lifetime. The most effective way at this time to ensure that the particular product you are interested in purchasing is designed to withstand high-heat applications, is to check the packaging or contact the manufacturer directly.
