Lighting: My nebulous plan

Andrea — September 15, 2011

The time has come, the Walrus said, to start deciding on interior fixtures and finishes. I've been focusing for so long on things like the foundation and the building envelope that it feels weird to focus on mere fripperies, but I can put it off no longer. Admittedly, I picked out my kitchen faucet years ago (I installed the same one in two previous houses), but I'm in a fog when it comes to interior lighting.

Ted had the clever idea to use LED strip lighting to give rooms the ambiance of a dorm room lit by Christmas lights. It's a soft, friendly sort of light, which is all we'll need when we're using our laptops (i.e. 90% of waking hours). Furthermore, we could use RGB controllers to change the light color, which would look pretty darn excellent. And of course we'd have some bright overhead fixtures for times we want to actually see things and not just pass the bong around. (I'm speaking figuratively, not literally — Ted and I are utterly and perhaps boringly substance-free.) LED lighting: Energy-efficient and mighty slick.

Alas, I've found no examples online of what we want to accomplish. I've found a lot of McMansiony-looking LED cove lighting, which is not our style at all. I'm imagining LED strips tucked behind curved moldings but not so close to the ceiling. Ideally it would bathe the wall in weird indirect light and look really cool.

But I have no idea if this would work. I suspect you need something above the LED strips to reflect the light back down. Furthermore, there are heaps of LED vendors online but I've heard there's a lot of junk out there. So today I called a lighting consultant recommended by Eli to see if he can help me navigate this bright glowing sea.

We spoke briefly on the phone and he warned me that LEDs are currently more expensive than conventional lighting (sigh). He confirmed that most of the LEDs available online are crap (and no, he doesn't sell anything himself — he just provides recommendations). We'll probably set up a meeting with him to discuss our wild notions and to see if we're heading in the right direction.

As for the overhead bright lights, I think we'll use a combination of LED recessed lighting and hanging fixtures fitted with GU24 sockets [ETA: Or not — see below.]. That is, if someone doesn't convince me that GU24s are a flash in the pan (ha!) and that this recent article about GU24 lighting from Green Building Advisor is all wet.

I have a sinking feeling that LEDs are not quite ready for prime time, which is frustrating because they surely will be within a few years. And of course they use a mere squeak of power compared to incandescents, and they are less flickery and annoying than CFLs.

Words of lighting wisdom are welcome!

[Added on 2011-09-18:  Erik Haugsjaa emphatically pointed out that GU24s are best suited for landlords or developers who want to force residents to use energy-efficient bulbs and that they're actually a terrible choice for us, given the lack of fixtures available. So we'll go with good old Edison overhead fixtures instead.]

Hi!

I'm trying to do the same idea with the "downward-onto-the-wall" LED lighting. I also picture it behind molding of some kind, and I'm sure it could be done using good old Home Depot LED rope.

Everywhere I've looked online so far (except for here!) only shows "upward-onto-the-ceiling" lights.

If you'd like to stay in touch, I'll let you know how I do (and vice-versa?)

Good luck!

Maureen

Hi Maureen,

We met with the lighting consultant a few weeks ago and he had some good suggestions. It's a little vague so far (we need to meet again and cover details), but I'll share what we find out.

One thing I learned was the term "wall washer," which refers to that effect. If you Google it you might find some helpful results.

Best wishes,
Andrea

The passive house display at the mn state fair had a very cool led lighting detail around the windows and doors you can see a picture here http://ndsudesignbuild.files.wordpress.com/2011/08/photo22.jpg?w=584&h=781
but it really doesn't do it justice. they design was by the ndsu architecture dept maybe you could contact them for supplier info.
love the blog and house keep the info coming.

DO NOT DO GU24!

Erik Haugsjaa — September 16, 2011

The comments in the GBA article are right "High Volume means Lower Prices, so stick with Edison"
To me, the purpose of GU24 is for developers to force owners/renters to use CFL or LED. But if you are building the house for yourself, do edison! You'll find better and cheaper lights!

Wow, thanks for the urgent warning! Next time just post a link here ;-)

I shall heed your advice and look for Edison fixtures instead. Of course, that'll be a whole new time sink because there are about a zillion more to choose from...

I'm building in California at the moment, where you're required to use GU-24s in the kitchen/bath (Ok, its a bit more complicated than that, but essentially true) as part of California's "stringent" Title-24 energy requirements. So far I've put in junk fixtures, or found ones that I can change out the socket to an Edison, so that when LEDs are ready for prime time, I can put them in. The California energy commission claims that these lighting requirements have saved significant energy, but presumably that's due to the overall population being not very energy conscious. GU-24s are just California's way of attempting to force energy efficiency.

BTW, in my previous house in Seattle, I spend a few weeks attempting to measure how long various light bulbs where on in a given week, and then put together a spreadsheet of all my electrical loads. What I found is that many bulbs were rarely on, and could stay as incandescent with negligible energy penalty. Admittedly I'm a bit fanatic about turning out lights, and that I had other bigger problems (like 18w standby on the modem/router, too many appliances that come with clocks, etc).

Andrea,

You might find this lighting setup interesting.

http://vtecobuilder.com/interior-design/lighting-soffits/

Depends on the shape of your house, but i imagine you could integrate something like that into the walls as well, with a standoff piece ofmolding, color matched to the walls... They had a very nice lighting setup in the kitchen as well, check through their posts, they mounted the cabinets about 2" off the wall, and hid some ballasts behind that pushed light both up and down.

Very nice effect.

Nice. We'll have a vaulted ceiling upstairs, so something like that could work for us. And that blog seems to have a lot of other stealable ideas -- thanks for the pointer!

Do you really need solar panels?

Before installing solar panels, get a home energy audit to find out where you're wasting the most energy. Your house will be more comfortable if you seal leaks and add more insulation, so don't just slap solar panels on the roof without curbing energy use.
