Home Automation – Choosing Bulbs

With a New Year’s resolution to replace all incandescent bulbs in the house with LEDs, I actually started the process back in December.  I purchased a ton of these:

Sylvania Ultra LED Light Bulb

These bulbs were already cheap at the local Lowe’s Home Improvement store.  But, for Christmas, they were $2.20 each!  Well, I only needed 7 more to finish up the job I started, in terms of flood light replacement, so I got them.  At this rate, they’re cheaper than incandescents, by a long shot, so why not?

For my particular house, the vast majority of bulbs in common areas, are these floods, so replacing them all will make us feel good about the environment.

In most cases, these bulbs are in sets of at least three or more, so there’s a question of the light switch that goes with them.  In two cases, the family room and kitchen, there are mechanical dimmer switches.  Those are older Lutron dimmers, which were good for the older floods, but not tuned to the all new LED floods just installed.  They work, but in a kind of clunky way.  When you dim really low, the lights might start to flicker, becoming unbearable to be under.  So, some new dimmers are required.

There’s a whole story on dimmers waiting to be written, but there are basically two ways to go.  Either stick with another simple mechanical dimmer, with no automation capability, but at least LED savvy, or go with an automation capable dimmer.

This is as much a cost concern as anything.  I went with both depending.


This is a typical mechanical dimmer.  I chose Lutron models that are pretty much the same as the old ones, except they handle CFLs and LEDs much better.  This is a good choice when you’re not going to do any automation in the area, you just want to slap that switch on or off when you enter and exit the room, simple and sweet.  So, in my kitchen nook, which has 3 lights, I put this one in.  I also put it in for the 9 lights in the kitchen, but after some thought, I decided I want to do some automation for the kitchen, so I need an automatable switch instead.


In this case, it’s a dimmer that works with the Lutron Caseta automation system.  There are myriad automation systems from all sorts of companies.  I went with Lutron because that’s what was already in the house previously, and I’ve known the name for at least 40 years, and the reviews on them seem to be fairly decent, and they work with the Alexa thing.

These are great because they work with the LEDs, they’re automatable, and you can still just use them locally by pushing the buttons for brighter, dimmer, on, off.

So, that covers most of the lights.  But what about all those others, like the bathrooms, bedrooms, entry way, porch, etc?

Well, in most cases, you can just replace a typical 60 watt bulb with the equivalent 9-11w LED equivalent.  Choosing a color temperature (2700 – 3000K probably the best).  These can still work with standard light switches, so nothing more to be done.  Probably not worth installing a $50 automated dimmer on each one of these lights, but you could if you wanted to.

Now, there are some spots where you actually want to do a little something with color.  In my house, perhaps on the balcony (3 lights), or a play room, or prayer nook.  In these cases, you can install something like the Philips Hue.


This is a bulb that is individually addressable.  It requires yet another Hub device, this time from Philips.  What you get though is the ability to set the color to a wide range of colors, as well as the general dimness.  You can set scenes, and if you want to write a little code, you can even hook up a Raspberry Pi to change the color to match the natural daylight.

At $50 a bulb, this is a very spendy option ranking up there with the choice between mechanical and automation ready dimmer switches.  In this case, you get the automation without having to install an automation dimmer, but you pay the automation cost for every single light you buy.  So, for my balcony, it would cost $150 for three lights, or I could go the standard LED and dimmer route for more like $60, assuming I already have the appropriate hub in either case.  What you lose with the standard bulb/dimmer approach is the ability to change the color.  For my balcony, I don’t need to change the color.

So, these automated colored lights make more sense for something like a bathroom, or an office space, or somewhere else where you spend time and care about what the lighting color is doing.

And there you have it.  No matter what you choose, they MUST be LEDs.  At least that’s the mantra of this day.  then you are free to choose a mix of automated dimmers/switches, and automated color changing lights.  In the future, for new homes, all the lighting will be LED at least, because it’s becoming the cheaper choice for builders.  For higher end homes, I’d expect there to be hubs, with automated dimmers and colored lights as a standard set of choices the homeowner can choose, just like carpet, paint color, and cabinetry.
