This chart that I found on the Pure lighting website might come in handy in the jungle of new definitions, acronyms and terms.
Incandescent bulbs have a perfect score (100) on the Color Rendering Index (CRI) – No wonder we love them so much!
But they unfortunately aren’t that effective in putting out a lot of light in comparison to the energy they consume.
The good news is that some LEDs (that we carry in stock) are getting there at a CRI of above 90.
Incandescent, CFL, LED
We all pretty much know how bright a 100W bulb is.
We have also grown more familiar with the compact fluorescent lamps, even though there seems to be some confusion as to “translating” the brightness of the two.
“What is 15W fluorescent comparable to?” We often hear that question in our showroom.
And then there is the LED. And all the packages now talk about is lumens. Why can’t they just give us the measurement in watts?
Well, watts are actually a measurement of energy use, not brightness. A compact fluorescent bulb might produce the same amount of brightness as your traditional incandescent bulb, but will use a lot less energy, or watts. Lumens tell you how much light you are getting from a bulb.
The back of each package of light bulbs now have a “Lighting Facts” label modeled after the “Nutrition Facts” label on food packages. The Lighting Facts label will provide information about:
- energy cost;
- the bulb’s life expectancy;
- light appearance (for example, if the bulb provides “warm” or “cool” light);
- wattage (the amount of energy the bulb uses); and
- whether the bulb contains mercury.
I love it how the lighted IN-EI sculpures by Issey Miyake enhance the windows of our showroom.
Yesterday I enjoyed a beautiful sunset on the mountains across the street while the IN-EI sculptures were glowing in the fadng light.
They are all so stunning!
This is my favorite: the Mendori. It looks different from every angle.

Oh, I love that light!!
5W LED, how bright is that, like in Watt?
In our showroom we constantly get questions like that about the new LED lamping. Understandably so, since it’s a totally new concept for all of us.
Here are some watts-to-lumens equivalents for light bulbs:
- To replace a 100-watt incandescent bulb, look for a bulb that gives you about 1600 lumens.
- To replace a 75-watt incandescent bulb, look for a bulb that gives you about 1100 lumens.
- To replace a 60-watt incandescent bulb, look for a bulb that gives you about 800 lumens.
- To replace a 40-watt incandescent bulb, look for a bulb that gives you about 450 lumens.

With the huge generation of baby boomers defining “growing old” in new ways, there is great motivation to find solutions to the pesky physical problems associated with aging.
One is the research being done on “Lighting for the Aging Eye”.
What it all boils down to is that we just don’t see so well at 60 as we did at 20.
But then again, this is no reason to limit our activities. We just need to know what to do about it and make some changes in our home, and off we go!
In our new showroom we have made a fun display using this iconic poster of the buff 70+ year old guy with a few lighting facts about “Lighting for the aging eye.”
At 65 you need:
- up to 10 times the amount of light as the average 20-year-old.
- a light level of more than 100 foot-candles to be able to read comfortably.
Lighting manufacturer Holtkoetter has initiated and supported extensive research at the University of Colorado to study and develop the scientific basis of lighting for the aging eye and to research how good lighting can mitigate the effects of the natural physical changes we are all subjected to as time passes.
The findings were that the decrease in retinal illuminance requires a light level of more than 100 footcandles for optimal reading performance.
Holtkoetter therefore chose a 75-Watt or 100-Watt Halogen light bulb by Osram.
Its shape and the construction of the inside of the reflector, allow for a light level in excess of 100 footcandles.
A matte glass diffuser and a reflector that focuses the light only on the reading material will reduce glare and scattering.
Adjustable dimming controls and the adjustability of the physical reflector location allow the light levels to be set at the optimal position, reducing the need for the eye to adjust to different light levels.
The study resulted in a series of table, chair-side and floor reading lamps.
One is an absolute winner: The Bernie LED floor lamp!! Priced at $898 it’s definitely not cheap, but it’s light output is just incredible! Equivalent to 1200 Lumens in an LED lamp! That’s big!!
The sleek and innovative Bernie Turbo Series Swing-Arm floor lamp is the 2011 winner of “Lighting for Tomorrow” competition that recognizes the best in decorative energy-efficient light fixtures.
With its 8 Cree LEDs it has an amazing light output of 1120 Lumens, which is equivalent to 80W Halogen!!
Like many of the Holtkoetter Lights, the Bernie LED floor lamp as the P1 Dimming System.

Vintage Edison Bulb
Many have asked us if the exposed-filament bulbs, reproductions of Thomas Alva Edison’s first light bulb will be available in a few years.
So far the answer is yes.
Because they don’t produce enough light they are considered specialty bulbs and are not included in the higher federal efficiency standards that gradually begin taking effect in 2012,
Aware of the need to conserve energy, it is my recommendation to use these wonderfully warm vintage lights only as accents.
Use the more efficient light sources for the majority of the illumination for your home.
We will be adding more of these bulbs to our site in the next days at prices of around $10 each.
They actually last quite a while, and in my opinion are a low-cost way of adding ambience to a space, just like candles.

Stella Ceiling Fan by Modern Fan Co.
The Stella ceiling fan was designed by David Ellis for the Modern Fan Co.
This contemporary fan is a beautiful combination of air management and superb ambient lighting.
The wood accents and blades add warmth and allows it to fit a large variety of locations.
The central glass cylinder is surrounded by maple or mahogany plywood rings. It is available with a dark bronze finish and the choice of black, maple or mahogany blades
For the fifth time since its inception, Hubbardton Forge has awarded the prestigious Vermont Governor’s Award for Environmental Excellence & Pollution Prevention.
This prestigious award honors Vermont companies that use innovative approaches
to reduce or eliminate the generation of pollutants and wastes at the source. Hubbardton Forge received the award in 1995, 1996, 1997 and 2005 for several advances they made in their finishing systems.
This year, Hubbardton Forge was recognized for their adoption of automated centrifuge separation technology. This change resulted in a 97% reduction in water usage, a 150% increase in cleaning efficiency, elimination of a hazardous waste stream, improved worker safety, improved part quality and a reduction in labor.
Only 26 days left !
The upcoming EU ban on frosted incandescent bulbs will start on September 1st with 100W bulbs.
Other wattages will then be phased out over the next three years.
With the deadline for the demise of the familiar light bulb rapidly approaching criticism of this legislature is spreading throughout Europe.
There are calls for civic disobedience and protests about “Light Bulb Socialism” (Holger Krahmer, FDP, Germany.)
It’s not that all Europeans have all of a sudden fallen off the wagon and decided to be energy-hogs. This is rather a widespread scepticism towards EU bureaucracy and the rush to force this legislation through before a suitable replacement for the incandescent bulb has been found.
Many are complaining about the quality of the light emitted by a CFL bulb, that it is not strong enough for tasks and can cause headaches.
Others are pointing out that the issue of CFL recycling has not been solved and that the research about the virtues of CFLs comes primarily from interest groups like CFL manufacturers and is grossly overstated.
One group is not complaining, though: light bulb retailers. Sales have skyrocketed over the last months as shoppers are stockpiling incandescent bulbs.
Museums, galleries, stores and general consumers are making sure that they still have a choice after September 1st.
Ingo Maurer Lucellino
“What a sick idea to eliminate an icon like the light bulb”
When we were in Munich this spring and ran into Ingo Maurer the discussion regarding the new European regulations to ban the incandescent bulb by September were heated.
Never one to just accept things passively, Ingo Maurer was using his showroom to demonstrate how silly the new rules are.
I’ll never forget his display of the charming Lucellino desk lamps outfitted with squiggly compact fluorescent lamps. Horrid! More »
