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 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.
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.
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.
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.
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.

Awesome jom im doing this on mine right now appreciate you posting this my friend ❤

Interesting video, what’s your runtime with the 18650.
SORRY I HAVE NOT TIMED THE OPERATING LENGTH. I GUESS I NEED TO DO ANOTHER VIDEO SHOWING HOW LONG THE LITHIUM BATTERIES WILL LAST.
Nice job old man. Get your care taker to trim those nails. Do hand exercises to loosen up your joints. Pain is good. ❤

@@stoopidhaters bulb probably has a wide range acceptable voltage input. That way one bulb can fit all their lights.
Also, 3 alkaline cells would put out 4.5
