LED Lights – Good For Prepping and The Planet

Electric light bulbs freed Americans from the energy tyranny of kerosene, candles, gas, and even whale oil. Having a safe, clean form of lighting finally fulfilled the long human dream of fully owning the darkness. However, for over a century, the basic idea of what a light bulb was remained largely unchanged. Typically a glass bulb with a tungsten filament in a near vacuum, lightbulbs were a somewhat stagnant technology.

They were also energy hogs, wasting much of their energy as heat, rather than light. Of course, at times, that heat was valued, such as when used to heat chicken coops, but other times it was unwelcome. The excessive electric use of such bulbs could also be unpopular, which helped drive lightbulbs that used less energy, put off less waste heat, and even more natural lighting.

Today, incandescent bulbs are increasingly quaint old fashioned technology, while modern incandescent and LED bulbs are the way to go, with LED bulbs demonstrating superiority in nearly all cases. With many preppers looking for ways to save energy, or who need energy-saving light bulbs because they are going off the grid, we’ve prepared a handy guide for choosing your next lightbulbs.

LED The Way…

Forget fluorescent bulbs, they are a waste of time in this day and age. Cheap ones contain mercury, they give off a weird light most of the time and bring little of value to the table. Modern bulbs use less energy, give off cleaner, more natural light, and are increasingly priced about the same. More importantly, they last much longer, as much as 25,000 hours of use – that’s almost three years of continuous operation!

Of equal interest to the prepper, are the huge numbers of 12 volts LED bulbs on the market. This makes retrofitting a car, camper, RV or boat to LED lighting crazy easy. And you know these battery friendly bulbs will stretch your charge out.

But why should you choose LED bulbs? In a nutshell, they simply offer better performance. If you are running off a battery bank, they are the only logical choice for lighting due to their low power consumption. If you are looking to recreate natural light, many LED bulbs mimic natural daylight. And if you just want to save money on your power bill, again LED bulbs sip power.

LED Power Consumption

Because people are still familiar with the light output of old incandescent bulbs, many LED light bulbs advertise their equivalent brightness to incandescent lighting. However, something like a 100-watt equivalent bulb will not use 100 watts of power to operate. Instead, it will use about 14 watts of power. 12 volt LED bulbs can use about ⅓ the wattage of a normal incandescent bulb, which makes them vitally important for off-grid use.

Only you can determine your power consumption, and how to allocate it. Some people minimize lighting in their off-grid planning in favor of other things like refrigeration or communication. However, without sufficient lighting, your off-grid retreat might be unsafe, or an attractive target to thieves.

But power consumption isn’t the whole story. LED bulbs are wrapped with confusing ideas like lumens, and CRI’s, so let’s take a look at those in order.

Let There Be Bright

Light output is measured in lumens. While that might sound like a weird disease, or possibly a fringe political movement, lumens are simply a way of measuring how visibly bright light is. Without going into much detail, suffice it to say that the more lumens, the brighter the light.

As the Department of Energy article linked to in the first paragraph indicates, modern light bulbs are bought by examining the number of lumens they put out. Now is also a good time to consider just how much light bulb you really need.

Because many modern LED bulbs simulate natural sunlight, you might find you don’t need as many, or as bright of bulbs as you think. When preparing your off-grid lighting plan, realistically consider how you use lighting. How often can natural light through windows or skylights work for you? Can you use a lower power bulb in some rooms or fixtures? Consider using light colored paint in rooms when you can.

Off gridders will quickly recognize the value of careful placement of lighting, and making use of just enough bulb, and will see their power consumption drop accordingly.

Color Rendering What?

Many LED bulbs advertise a CRI number, but what is that? CRI is the Color Rating Index, which determines how well a bulb shows colors based against a baseline standard, which is usually natural light.

Now you are probably sitting here going “You’ve written cooler articles than this one Steve, what gives with all this lightbulb stuff? I just want to stick a bulb in my lamp, and call it good. After all, time is running out before the next Carrington Event wipes out all electrical appliances as we know them anyway!”

Well, that is certainly an option, but there are practical reasons for even the most hardcore preppers to care about the CRI of their lightbulbs. Some people are sensitive to certain shades of artificial light, and choosing a CRI that matches that of natural life may be an actual physical relief for some.

Then too, there is a simple quality of life. If you don’t like the light your lamp puts out, you will be less comfortable in your prepper retreat, and the subtle stress of low-quality lighting is one more thing you don’t need, especially in an emergency. Unnatural light may also cause eye strain, making reading or television watching harder.

You might also want natural looking light when dealing with medical conditions. Being able to clearly and accurately examine a wound or other injury could be important. Plus, it really is just nice to have lighting you are most comfortable with.

You might have to play around with different CRI’s to find the kind of bulb that works best for you, but the quality of life improvement really is worth it. There is no need to tough things out just because you are off-grid.

But Does It Really Matter?

I know some elements of the prepper community are set in their ways, and there is nothing wrong with that. After all, it is a survival trait to not discard what is proven to work well, and despite changing government regulations that are driving many “inefficient” light bulbs from the market, good ol’ incandescents still get the job done.

But they do so in a wasteful manner, and waste is not something a prepper should tolerate. When you are driving for self-sufficiency, an important part of that is to minimize needless consumption. This is even more important if you are off grid and making and storing your own electric power.

There is also the practical aspect of having long life light bulbs for the home or prepper retreat. Incandescent bulbs can burn out in months, while LED bulbs will last years. If you are stockpiling supplies, one LED bulb can replace many incandescent bulbs, which makes your preps more efficient, and possibly cheaper.

Drawbacks Of LED Bulbs

There are of course a few drawbacks to LED light bulbs that should be considered. For instance, many bulbs will overheat when put in an enclosed lamp or fixture. While this would seem unlikely given their low power draw, remember, these bulbs are electronic devices, and all electronics generate some level of heat. When operated in a closed fixture, many LED bulbs will eventually succumb to overheating. Choose bulbs that are specifically rated and designed for use in enclosed fixtures.

Another big drawback to some is that LED bulbs don’t generate enough heat. Incandescent bulbs have long been used to keep chicken coops warm in the winter, or to provide a source of heat in enclosed spaces, or to even help keep pipes from freezing.

While there are other solutions for those issues, you have to admit, that sometimes, nothing beats the quick and easy heat output of an old fashioned 100 watt light bulb.

These drawbacks are trivial though, compared to the great advantages offered by LED bulbs.

Conclusion

The practical nature of electric lighting is sometimes overlooked by preppers. If they do think about it, it is when they are designing an off-grid power system, and even then, they might not give too much thought to it.

However, LED bulbs can be an important part of your energy self-sufficiency, and when stockpiled, an important part of securing the future against uncertainty and unrest. Plus, they simply save you money on a regular day to day operation.

By using and storing LED bulbs, the prepper is less reliant on corporate power infrastructure, uses less energy, and saves more money. Sounds like a few good reasons to use LED bulbs to me!

  1. I have found that if you use an over-the-air television antenna cheap LED bulbs can wipe out your signal with interference. Also I would not recommend “Feit” brand bulbs from Menards. Installed 10 of them about two years ago, four have failed already.

  2. I really like the CFL in the opening image talking about LEDs.

    I would take this article with a grain of salt.

  3. I personally picked up a few 12 volt RV LED bulbs to use with my battery back up system. No need to use a power inverter to run the bulbs ( saves on power). I also have some USB powered LED bulbs that work great with a portable power bank. They have a hook on the end so you can hang them up where ever you need lighting. Work well in tents when camping. When we lost electric for 6 hrs these came in very handy to have lighting where I needed it most.

  4. I would only use LED lights outside but not inside the home. They are not good for the eyes. I go monthly to a micro acupuncturist who is a world leader in this type of acupuncture. He told me this plus it is on the internet. Be careful!

  5. LED lamps for continuous duty (as defined in the NEC) is certainly not ready for prime time–especially at their price points. However, they are improving. I use both and when their reliability improves to justify their cost, then I will use them exclusively.

    I still think incandescent lamps have their place in certain agricultural applications (incubators, rookeries, ckicken coops, etc…) So they shouldn’t be discontinued, rather, improved upon.

  6. I have worked in front of a computer for 80 hours a week for the last 2 years. I now have cataracts so bad that my vision is blurred and am getting ready to have surgery to remove them. Doctor says its blue light from the monitor. Also told me to replace them in my house. Several cities have started removing them from street lights.

  8. I hate CFL lights and will never buy another. They do not fail they just grow weaker and weaker until you have to check the switch to see if it is one.
    One great application I have found for LED bulbs is center of the room light fixtures that have the light bulb receptacle holding the light bulb up side down. In this position an incandescent bulb will transmit all of it’s heat into the bass and eventually cook the wiring connections on the bulb receptacle. The low excess heat LED never damage the connection at the receptacle.

  9. Some reports indicate LED’s (diodes) may not survive an EMP. At this point, mostly speculation as few (modern day equipment) testing reports are available. I’d still keep a few incandescent bulbs around just in case or put a few LED’s in your Faraday. Moot point if you don’t have working long-term back up power after the grid crashes.

  10. led and cfl lights which are “high kelvin” produce near daylight light.
    this is useful for choosing true colors. for example, my sewing space is all daylight/high kelvin leds and cfls. the yellow light we are all comfy with was made to emulate the yellow light produced by gas lights and oil lamps.

  11. I used 12 volt CFLs in a 12 volt solar powered house in the early 90s and they reduced our power consumption over the incandescent bulbs by about 70 percent. They were a great innovation 30 years ago in a remote cabin with no grid hookups. HOWEVER, they are like a model T Ford compared to a Lexus in 2019. Why? For starters CFLs have a high mercury content, so high that in their heyday, you would sometimes see news items about evacuations of rooms and hazardous waste teams being sent in to clean up a broken CFL bulb.
    Another point is that while CFLs were way more efficient than traditional incandescent bulbs, LEDs use less than half the wattage for the same brightness a CFL uses.
    Most LEDs are dimmable and no CFLs are dimmable. Then there is the fact that you can get LEDs that emit almost any color of light, unlike CFLs. I could go on but I wont.
    Could you please tell me why you feel that CFLs are better than LEDs?

  12. To add to an already GREAT article, we have bought most of our LED 60
    Watt equivalent bulbs at Dollar Tree. Some have been in daily use for over 2 years with NO failures! Only come in 60 watt equivalent. 800 Lumens. 3000 K not too yellow. Not hot enough to burn your hand. Use in any position. Got our $1.00 worth!
