What I am seeing advertized, and what is discussed here, are LED replacement bulbs for fixtures designed to hold incandescent bulbs. I think that most people are going to have problems plunking down $50 for a light bulb after getting them for a buck or two for so long.
There is also the...
Every so often I read about a proposed ban on incandescent bulbs. I wonder of they have really considered impact. I use CFL wherever they fit but there are exceptions. No CFL, or even LED, is going to be happy replacing the light in my oven or dryer. They just don't like the heat.
There are...
I remember when TV remotes didn't need batteries. No Joke. The first remotes were mechanical and used a tuning fork to send ultrasonic signals to the TV. Now we have these monsters with so many buttons I am embarrassed to try and explain them all to a non techie.
Using candles instead of a...
I suggest that you get some scrap, an old circuit board or some copper wire, and practice on it first. Remember that you heat the wire so that the solder melts and coats it. If you just melt the solder and dribble it on then the joint will not be strong.
It helps to poke a tiny bit of solder...
I had to consider the same issues and chose the Streamlight Microstream. This is a 1xAAA size so it is small. It has a forward clicky and is very easy to use. She started out wearing it on a neck lanyard but now uses the clip to keep it in her pocket. This is better than the purse as she...
There are a lot of batteries that COULD work but might not be practical. There is a small 12V battery used in garage door openers that would work but it would drain it very quickly. Basically the smaller the battery the shorter the run time.
Almost any combination of cells that will total 12...
Juggernaut,
Thank you for the calculations regarding total energy. It is nice to know that the L92 has more capacity that an equivalent size Li-MnO2 cell would. That certainly removes one reason for wanting that chemistry in an AAA cell.
On the other hand ... I can buy the CR123 for a buck...
It seems like for every discussion of a new AAA light, the Fenix LD01, the Maratac AAA, etc. one of the first questions asked is will it accept a lithium ION. They all seem to run a lot brighter on 3.6+ volts, go figure :-)
I have not found a reference on the energy density of the L91...
I have seen multiple discussions about using rechargeable Lithium Ion cells, 10430, cells in AAA lights but not primary cells. If CR123 cells come in both flavors then why not AAA or AA? (The L91/L92 cells are 1.7V and don't count.)
The reason I ask is that some of the lights seem OK with 3V...
Re: New Nitecore EZ CR123 CR2 lights
Just checking on that ... P!D is 71x21mm while the EZ123 is 70x19. I doubt I would notice that unless I had them side by side. Quoted brightness and runtimes are very close. I would want tests to rank then rather than trusting the sales blurb. Price is...
Had my p1d q5 for almost a year now; on a 2nd battery now. I was dithering between it and an L0D. Still love it.
Yes, because it is a twisty, it can be difficult to use one handed. I can turn it on with one hand but it doesn't always stay on which can lead to it cycling through all the...
I think it comes down to what size you are willing to carry. I have had a lot of guys tell me they have a great flashlight. When I ask to see it they say they don't have it with them because it is too heavy for their pant's pocket.
We are talking EDC here. That doesn't mean just exploring...
I went through this selection process back in October. I finally settled on the Streamlight MicroStream. My reasons were:
Simple interface. No modes to cycle through. Strobe and SOS are just going to annoy her. Also a button is easier for her than a twist.
Good brightness. I didn't think...
Re: Lithiums or Alkalines as "Emergency Backup batteries"? (Have around 12 Eneloops)
Lithiums also handle heat better than alcalines. This is important if you are storing them somplace that can get hot such as in a car.
It would be a lot more efficient to get a coin cell keychain light with a red LED. And before you complain about having to carry something extra note that they are not much bigger than the red filter you are lugging around.
Taking a violet blue LED, using that to excite phosphors to make...
