Excellent. I am considering this myself, and as such, you've given me fuel for thought. You can get led bulbs of greater voltage to adjust to the greater battery output.
I've got a 2D maglite. I wouldn't mind trying to make a holder the size of the 2X D cells, and then a voltage converter inside it to provide a steady 2.4v to the bulb (I see it's rated 2.4v). I think that's to compenste for the voltage sag of the alkaline cells when powering a relatively high current lamp. I'm thinking I could even implement a USB charging port in the end cap. I know you can get more modern lights with LED's, but I still prefer the look of the old school incandescent for general use. They're still plenty bright enough.
I agree buying batteries gets old and I’ve ruined one with leakage. Since then I’ve switched to energizer rechargeable D batteries. Not cheap to start but worth it. The batteries are much lighter too. Around $35 for a charger and around $6 per battery. I just recharge them every 6 months to keep them fresh if I don’t use them. I will say you should unscrew the tailcap when you’re not using it so they don’t drain because they will. I have around 10 maglites so I know. ML50L and the ML300L models. I do wish maglite would update or offer a D size light that takes AA. I like buying made in the USA but their tactical lights are lacking. I purchased a Nightcore P23i and it’s impressive. I still like the simplicity of a maglite though. Mine have “modes” you can set and click thru which are nice. High medium low strobe and in different orders.
Good day. The fact of changing 3 D-type batteries for 2 18650-type batteries strikes me because of the voltages they handle. 3 D type batteries add up to a total of 1.5 * 3 = 4.5 volts and two 18650 type batteries add up to a total of 3.7 * 2 = 7.4 volts. Be careful, the led can support that voltage and nothing happens, I don't know because I haven't done the test but the difference is quite considerable. Greetings.
what you do is get a wide range led that can handle the voltage and works just fine. i'll be building about 10 maglight 1 in everyroom. but now i'm working rebuilding tool batteries with success so long as my body doesnt give out.
SURVIVAL gear ⚠️ ALERT tip: All of the LED flashlights will be fried, destroyed when an EMP hits them 🔦 You should ALWAYS carry an incandescent type of flashlight as a backup to your LED flashlights and carry a mechanical wrist-watch as a backup to your digital watch ! *Please also research which two-way communication handheld radios cannot be destroyed by an EMP.
@@unitedstatesirie7431 i don't think so I have them on 3 flashlights without any issues. I have use the one in this video and the cells are still loaded with voltage no recharging the cells yet. I use a variable led.. so whether its 2 volts or 12 volts it will work.
How did the bulb not Instaflash? Remember, 2x Li-ion cells are 4.2V off the charger so that 3 cell Incandescent bulb which is rated at 3.6v was getting hit with 8.4v. Unless you changed to a 7.2v Bulb (6 cell).
nope flashlight worked as is with the orginal incandescent bulb. nope never burned out. still working. now i did do another video with more volts and it did blow the bulb on a bigger maglite. but i was changing it anyway to the new led upgrade.
@@grandpaworks8632 Well those batteries are pretty old so they probably didn't get up to 4.2 Volts when charging, and even if they did, they would have dropped to a lower voltage pretty quick.
@@blatantmisconception Well technically any Incadescant bulb has a wide range of acceptable voltages. But if you go too much over, the bulb will die instantly or quickly. The stock 3 cell bulb is rated for 3.6V but can be over driven to around 4.8V since Fresh alkaline batteries can be 1.6V (3x 1.6 is 4.8). But 2x Li-ion batteries would surely kill it so I've come to the conclusion that these batteries are old thus can't output 3.7V anymore.
