@sininetigu Considering LEDs are way lower in consumption compared to the filament bulb, it's going to last a lot longer. It's also brighter as well!. With this circuit, it's running at about 18 mA in current. With those energizer cells which are rated 55mAH, it should run about three hours. Remember, you still have spare cells you can use from just a single A123 battery. Thanks for viewing!
@SoundOut260 Technically, you can but it reduces the efficiency of the mod. You're going to add resistor anyway, why not just use just three cells, right? Thanks for viewing.
@tigreslokos Most LEDs you can buy operate at 3.3V. A single AAA battery is only 1.5V. It may work but it will not be bright enough. I think you can buy special LED in the internet that will just replace the lamp and still be bright. Those are a lot more expensive than the regular LED.
not necessarily, I have a 3.5V LED, and my supply voltage from batteries are 4.81V i used a 47ohm resistor, and it works like a charm... thanks for quick reply though, and for such an awesome video....

Did the same with step by step. Works great. Thanks a lot man.
One problem, It has poor light. if i ignore the resistor and put a simple wire as link then i get a bright light. Possibly this might reduce LED life i guess.
Most LEDs are rated around 3.3V. That's why the resistor is there for the voltage drop. Otherwise, the LED will get overvoltage and get burned out real quick.
Do we really need to solder the poles? Do you think it will work with simple glue? I tried to do it with glue, it doesn't work but there are a lot of things that can go wrong...
you could drill hole to each of the poles and get the resistor leads through the holes and bend them. you can glue them as long as you leave contact points. also consider that you are twisting the end cap as you close it so the contact points may move. that's why soldering them helps. i hope this helps.
simpler, better:

can you guess at all on the lumen output?

im curious, whats the runtime on those 3 cells?

Just did this.... and nearly blinded myself with the light. Thanks a ton for this!

Cant you just use the whole of the A23 12v and use a higher value resistor? to around 4.5v
thanks

what resistor w did you use ? thanks
SoundOut260 9 months ago
nice mod just 1 question do all A23 12v brands have the 8little cells in them thnks
SoundOut260 9 months ago
@SoundOut260 Yes, it's standard for A123.

There are different Wattages to the resister ranging from 0.5W to 5W and above. Which one should I get.
ynotsaurus 1 year ago
@ynotsaurus 0.5W should be good enough already

Guess what... I just contacted Maglite, and they said they are coming out with an LED solitaire in the beginning of 2011.

Hi, I realy dig this but I have a question...
If I buy the LED and put it in with no other mod to the light, will it work??

@djmramos oh so the problem is it would be under powered?
but would it be better than a regular Solitaire with only the LED upgrade?

How large a resistor must I use if I want to use the whole battery? Or are there downsides? Will the battery not last longer?
hathiphnath 1 year ago
Does the resistor have to be 68 Ohms? Or can use another resistor, say 100 ohm?,
ekstc 1 year ago
@ekstc Yes, you can use 100 ohm resistor as well. You can go higher than 68 ohms but not lower. Otherwise, you'll bust the LED.
