Perfect Bathroom Lighting

After walking out of the house with yet another razor nick on the chin or eyeliner that doesn’t exactly line the eye, you’ve finally realized it is time to improve the lighting in the bathroom. With bathroom remodeling pulling ahead of kitchen remodeling in resale value, it is a good decision. Where do you start? Relax. With a little information and a few quick decisions you can be out of the door each morning, clean shaven and nicely coiffed.

Perfect Mirror Lighting

Experts agree that the best way to light a bathroom mirror is placing a light on each side, then supplementing the pair with light from above. Lighting from three directions eliminates shadows and illuminates the face perfectly so shaving is uneventful and makeup application is easy. In any new construction or remodel project, this should be the aim.

With that goal in view, preference can now come into play. A single sconce on each side works well and there is a wide variety to meet almost any aesthetic preference. You might also consider a linear light, mounted vertically. This works especially well if multiple people of varying heights share a mirror. The linear pieces will deliver ideal light whether the user is short or tall. Mini pendants, while installed on the ceiling can be positioned so the light falls in the exact same spot as the sconces. This opens yet another avenue of options.

Lights on each side of the mirror should be placed from 36” to 42” center-to-center, 66” to 72” from the floor. If there are two lavatory bowls in the bathroom, don’t cheat! Treat each sink individually. Light should be equidistant from the center of the mirror/sink. In an effort to save money, some people will place one light between the bowls. To do this correctly, the distance between the centerline of each light and each mirror should be exactly the same, from 18” to 21” in all four spots. Failure to position the lights equidistant will deliver uneven levels of luminance to the face. If the sinks are father away, add a fourth fixture. On longer vanities, this will actually look better and more balanced.

To add illumination from above, I like to use a recessed can in direct line with the sink drain. Find the center of the drain and place a dotted line to the ceiling. That should be the centerline of the recessed light.

Some Other Considerations

Clear glass and vintage light bulbs are nice, but they make it difficult to see because of their piercing light and the glare that creates. In a bathroom, seek out, etched glass, white glass, etched cased opal glass (white glass encased within a clear layer that has been etched) or a fabric shade covering the light bulbs. This softer delivery of light will make functionality better and easier to use.

Is the room big? You might need to add some ambient light to the mix. A group of recessed cans, some decorative flush or semi-flush pieces or even a chandelier will work here. Connect them to a separate switch.

Add some LED tape to a separate switch and place it under the vanity or at the toekick. Alternately, connect one or two step & aisle lights to the switch. Either will add some interest to the room, but more importantly serve as a functional nightlight for safer nighttime navigation.

Pretty simple, right? One light on each side of the mirror. Each light should be equidistant to the center of the mirror. One light above, placed at the centerline of the sink. Pay attention to glare for more comfortable use and you’re done! Of course, this method might not work for everyone.

Three Steps to Buying LED Light Bulbs

I’ve been around lighting since I was nineteen years old. As the lighting world morphed from incandescent to fluorescent, then to LED, it was easy for me to understand the differences. For everyone else, light bulbs are just another thing to buy when you’re shopping for home essentials. Laundry detergent, glass cleaner and light bulbs. Easy, right? Well, it used to be.

Soap still comes in a bar and household cleaners still come in a spray bottle. While light bulbs look the same, today, there are far more decisions to make than selecting a 4-pack of 60 watt bulbs. Don’t worry. It just breaks down to three simple steps, color temperature, color quality and lumens.

Color Temperature

For the typical home, I recommend one of only two options, 2700K or 3000K. Nothing else. Color should be matched to the room in which it will be used. This will make every room look its best.

Use 2700K if you have warm color rooms with lots of beige, wood, gold and earth tones. The warmth of the 2700K light will reveal their tonal richness.

Use 3000K if cooler color dominate a space. Black & white, grey neutrals, blues and purples will appear more vibrant, more intense under 3000K light.

Color Quality

Color quality is measured in Color Rendering Index (CRI). This is a scale from zero to 100. A black & white movie has a color rendering of zero. The blood that runs down the drain in “Psycho” is of course red, but with no color rendering, we see it as black. With incandescent light bulbs, there was no choice in CRI. With LED, options abound.

I recommend seeking out a CRI in the mid to high 80’s. If you live in California, 90 CRI is the minimum available for sale. Keep in mind, there is a cost to achieve higher CRI, so if you do not see it advertised, be warry. Manufacturers will not want to hide a good CRI number.

Lumens

Wattage is a measurement of energy consumed to power electrical equipment. It has nothing to do with the amount of light produced. Because we have been using incandescent light bulbs for over 130 years, we simply got accustomed to using wattage. Lumens tell us how much light is produced by the light bulb. As we move into the future, wattage consumption is going to constantly change, so we need to become comfortable with lumens.

If you were buying an incandescent light bulb that consumed this quantity of electric power:It was providing this amount of light*    
25W150 lumens
40W450 lumens
60W800 lumens
75W110 lumens
100W1600 lumens
150W2600 lumens
*Incandescent candelabra lamping is lower.
Be careful. There are few to no LED candelabra based light bulbs delivering over 500 lumens at this time. That could change as technology advances.

The process of light bulb selection is not that complicated.

  1. What color does your room tell you to buy? 2700K or 3000K?
  2. Find a color quality CRI above the mid-80s
  3. Buy based on lumen needs, not the advertisement on the package

With those three simple steps, light bulb purchases can be as easy as buying paper towels.
