Tapping the wisdom of the crowd...how many LED flashlights?

LED Flashlights are everywhere these days...but just how many of them are in use and how many are sold each year?  I want to tap the collective wisdom of LuminaNET to try and answer this question...

Please respond to this thread with information you have about the ownership and use of flashlights wherever you have lived / worked / visited...answering the questions below will be helpful:

1) In a particular country or region:  How many flashlights or other low-quality LED products (in working condition) are owned per household?  How often do they need to be replaced?

2) Are low quality LED flashlights and other form factors the dominant or secondary light source?

3) Are you aware of any datasets or studies that document these products?  

Why care about this?

Most of us on LuminaNET are focused on delivering off-grid lighting that is powered by solar energy and lasts years but LED flashlights are also a big part of the story in many places.  A recent study from Lighting Africa found that in three towns in Kenya there has been fast growth in the availability and sales of solar LED lighting and this has also been accompanied by growth in the “cheap flashlights” segment of the market as well.  It makes sense, of course, that people are interested in low-cost LED flashlights.  They perform better than incandescent lights, can have similar operating costs as kerosene lighting, and are safer and more portable than fuel.  

There are lots of reasons we should care about how big the market is for these flashlights:

1) The spending in this segment represents an opportunity to reach people with better quality alternatives.

2) While switching from kerosene to flashlights may have important benefits on public health and even economic grounds, it is not clear that it helps the climate.  Dry cell batteries take lots of energy to manufacture so it is possible we are burning more oil and coal to power flashlights than was burned in the lamps they replace.

3) The toxic waste stream from lead in rechargeable flashlights may be a bigger story than we expect, particularly if they are treated as a disposable good and are disposed of in the “customary” way.  

The flashlights we have in mind are: 1) cheap, 2) bright at first but generally do not last long, 3) widely availble, 4) either dry cell battery powered or have a low-quality sealed lead-acid battery inside with grid charging plug built in.  The photo below shows a range of examples we’ve seen in Kenya, but as far as we can tell these are widely available across the developing world.  

 EDIT: Should have included this in the original post: Our findings in Kenya were that the market volumes we saw indicate there were about 1.7 flashlights sold in Kericho per person!  This isn't outside the realm of reasonableness though...if each household has 1 flashlight in working order and 5 people, selling 1.7 flashlights per year per person is about 8 flashlights per year in each household. We have anecdotal evidence they only last on the order of months, and this would be in line with the estimates (at least the order of magnitude).

In Nigeria they cost as low as 0.3dollars a piece.I think it is really Chinese dumping them.Most of my customers do show-off this type of lanterns and they have series of bad experiences with them.At a time we a follower also before knowing about solar lanterns.

Thank you for giving these insights from Nigeria.  How often would you say people need to replace their flashlights?  Also, how many are used daily in each household?  

Do I understand correctly that you used to sell them?  It would be interesting to hear more about your experience both selling and working with the suppliers...


You got it right.  In solar, if the items are too cheap...look out.  I focus on items that might be a bit more expensive but will satisfy the customers.  No need to create market spoilage with cheap products that end up spoiling very quickly.   

I haven't sold any before,we only use them few years back.My mum burnt most of them(around 20pcs).you know lighting is a problem here also.averagely a household in my area have an average of 3pcs,kiosk 2pcs,health centers 10pcs and they are soon to burn out.LONTOR(different model are common).We even have major market for them in lagos.

Wow, 20 is a lot.  How many weeks does each one last for households?

This is the kind of information that is helpful for understanding the size of the market...

In my house we buy maybe five at a time because they dont last.Some last a day,weeks or month it really based on luck.You cant understand how bad it is maybe you should visit lagos,nigeria SEEN IS BELIEVING.
Most people invest in them even though they will fail(most African ain't capable of analytical thinking) and when you show them a superior alternative(solar lanterns)they start to compare it with their crap.
