What Is a Bulb-Miser?     Bulb-Miser

A Bulb-Miser is the featured product of Bulb Miser, Inc. Or, it WAS their featured product. Bulb-Miser, Inc. went belly-up some time ago. Their product was a “temperature compensating thermistor” that served to preserve the life of incandescent light bulbs. You can read an old advertisement for the Bulb-Miser light bulb life extender here It was developed during NASA’s Apollo program so that electrical surges wouldn’t damage the Saturn launch vehicle.


After the Bulb-Miser was introduced, there were other, similar products introduced.  These served the same function and operated the same way: by being inserted into the socket of a normal incandescent light bulb-using lamp.  Some of these other similar products went by names such as Lite Preserver, Lite-Bulb Saver, and Energy Button.

Why Are People Looking for Bulb-Misers?     Bulb-Misers

People have started looking for Bulb-Misers due to the coming ban on incandescent bulbs. Amidst all the Global Warming clamor, the United States government decided to pass the Energy Independence and Security Act of 2007. The result? All 100-watt to 40-watt incandescent bulbs are to be progressively banned beginning in 2012. The 100-watt bulbs are first to go, and all the rest will follow by 2014.


But, people resist change. They particularly resist it when it is forced on them by bureaucrats. The Tea Party movement is gaining prominence, and it resents the fact that government is going to be denying them the right to use something they have used for years. 


Additionally, there are many people who have concerns over the “just trust us, they are completely safe” compact fluorescent lamps (CFL).  There is plenty of anecdotal evidence that claims the CFLs exacerbate migraines and can trigger seizures in people with epilepsy.  The EU has denounced these stories saying that there is no scientific evidence to back up such claims, and the American medical establishment will, no doubt, agree.  But, the numbers of individuals who claim to be affected by CFLs is not insignificant. 


CFLs also contain mercury vapor, a well-known toxic substance.  As much as 5 mg may be present in each bulb.  The components in these bulbs are so hazardous to health that hundreds of Chinese workers who manufacture them have been sickened by them.  Many even to the point of hospitalization.  There are lots of American mothers and fathers who do not desire such dangerous materials lurking inside the same abode where their young children spend their days.


Lots of folks just don’t like the incandescent alternatives either.  The fluorescent light is said by many to produce an austere environment.  And, the slight hum they emit can drive those with sensitive ears just as mad as a constant dripping. 


The bottom line: a large number of people are going to want to keep using the incandescent bulbs long after the government decided that it knew better than anyone else what was best for everyone else.  They will keep using their incandescent bulbs and even buy bulb-saving thermistors, if they are available. 


So, when the ban gets closer, people will start hoarding incandescent bulbs.  This happened in the European Union in response to their ban.  Without the ability to buy new bulbs, people will clear the shelves of all remaining bulbs and will want to keep the bulbs they have working as long as possible.  Enter Bulb-Miser, Stage Right.

How Does a Bulb-Miser Work to Extend Light Bulb Life?  Bulb-Miser Work

Electrically speaking, a thermistor is a thermal resistor.  When placed between a light bulb and the electrical source, it must reach a certain temperature to allow the current to fully flow to the bulb.  Most light bulbs “blow” with the initial surge of current to the cold filament.  Bulb-Misers force the current to slow down and warm the filament slowly.  As the thermistor warms, more electricity passes, and the light emitted from the bulb gains intensity slowly without sustaining an initial blow-out level surge.  This greatly prolongs the life of incandescent bulbs.

How Do You Find Bulb-Miser Light Bulb Life Extenders?  Bulb-Miser Where?

Evidently, Bulb-Misers are as rare as a Honus Wagner baseball card. And, without the looming discontinuation of incandescent bulbs, there wouldn’t be much demand for them now. There certainly wasn’t enough demand to keep Bulb Miser, Inc. in business. Good luck finding them on You can sometimes find them on Ebay listed under either “Bulb-Miser” or “thermal button,” but they aren’t cheap (you can also search for Lite Preserver, Lite-Bulb Saver, or Energy Button and find them occasionally). The last ones I saw were to-the-door for $50 (for two). They are scarce. But, as I’ll mention later, there are some practical Bulb-Miser alternatives.

What Are the Benefits of Bulb-Misers?     Bulb-Misers Benefits

The Benefits of Bulb-Misers are obvious. You keep your incandescent bulbs glowing longer. The American Incandescent Apocolypse of 2012 (and the hoarding that ensues) will make those who want to keep and use their now-banned bulbs want methods to extend their life. That is the major benefit of a Bulb-Miser: longer bulb life.

What Are the Drawbacks of Bulb-Misers?     Bulb-Misers Drawbacks

There are a few drawbacks to using Bulb-Misers, however.  Since the thermistor has to warm up before allowing the maximum amount of current to the bulb, there is a 30 to 60 second delay before your light gets bright.  Additionally, since there is an added component between the source and the bulb, it slightly decreases the amount of current that reaches the bulb.  Consequently, the bulb’s maximum brightness will be a little less than it would be without the Bulb-Miser in place.  And, most obviously, no one (of which I am aware) is manufacturing them. 


There is also the possibility of electrical shock, an increase in the heat of the bulb casing due to the thermistor, the cracking of the thermistor disc with torque from the screwed-in light bulb, and a decrease in the engagement of the threads of the bulb when screwing one into the socket.

Is There a Bulb-Miser Alternative?     Bulb-Miser Alternative

Currently, there is not Bulb-Miser alternative.  But there could be soon.  All it takes is one individual with The Entrepreneur Mindset to make it happen.  There will likely be a surge in demand for Bulb-Misers (or newly-named similar products) around the time the ban goes into effect.  Assuming no governmental persecution for a device such as a thermistor, there could be a big market for these devices (the components of which are relatively inexpensive and could provide a good return).


You can also buy a diode form of an in-socket bulb life extender from Ace Hardware.  They cost about $10.  You can buy them here.  You do lose about 25% of the light’s intensity with these.


While there is no exact duplicate of a Bulb-Miser available, there is a practical solution.  People wanting to retain the use of incandescent bulbs after the ban can buy (or hoard) 130-volt bulbs before it begins.  Here is why:

The Pros of the 130-Volt Bulb-Miser Alternative?     Bulb-Miser Alternative 130v

The standard voltage in use in American homes is 120 volts.  Light bulbs are calibrated to use this voltage.  However, if one buys and uses 130-volt bulbs with 120 volts, you get Miser-like effect.  And, you don’t have to wait while your bulb reaches its maximum intensity.  


You don’t get the slow current to the filament, but you get a stronger filament.  These filaments are much less likely to blow with a 120-volt initial blast.  And, it takes much longer for the red-hot tungsten to evaporate to a degree that compromises the filament.  In short, buying (or hoarding) 130-volt bulbs is a practical solution until a brave entrepreneur begins re-manufacturing thermistor units for use in standard lighting.

The Cons of the 130-Volt Bulb-Miser Alternative?     Bulb-Miser Alternative Cons

Using a 130-volt bulb as a Bulb-Miser alternative is not without flaw.  There is still an initial surge, but the stronger filament does a much better job of dealing with it for a much longer time than a normal bulb’s.  Also, there is approximately a 20% reduction in the overall light given off by the bulb.  So, if you wanted the amount of light given off by a 60-watt bulb, you would have to buy a 75-watt bulb to get the same brightness.
