Hmm, that’s not exactly safe is it?

What is its power level?

Nonetheless, great stuff.

I live dangerously LOL
Do you mean with the switches? Or the battery? The charger is actually soldered to the cell.
These are only around 1.5mw, fully potted, they do get warm.
For my personal use only.

Oof I was scared. 1.5mW is perfectly fine and legal to use.

In Quebec, that was the case until a few weeks ago when any kind of laser were banned if you are close to an airport.

Yeah I’m scared of the powerful lasers, thought about getting one many times but no.
These wee green fellas are plenty bright and pocketable, can actually see the dot outside during daylight 100m or so and the beam at night is great.

Sometimes when a project fails it opens a door to something that works pretty nicely. That’s what happened here… I was going to build up a 4C Maglite with an XHP-35 but it just really didn’t want to handle the power. I even stepped up to a thicker heavier copper heat sink, in testing that one I burned a black pit in a 35. Ok, so, moving right along… Decided to do something else with the 4C Mag… chopped it this morning. Big Smile

Here is the Black 1C (26500) Maglite next to a 2D for size reference…

Here is the 1C Mag next to my early purchased light, got this way back when I was first getting into lights… JayRob from CPF chopped the Red Maglite, ChicagoX from here finned a head, Elektrolumens made the triple insert, and of course, I tweaked it all somewhat. Big Smile

The new threads and o-ring landing cut into the chopped off 4C tube…

Ah, Maglite! Robust construction throughout, look how thick the tubes are!

Made the copper (Te/Cu Alloy) sink on the lathe with a bit of a column to allow for focus like Mag’s are known for, hand cut the opening of the tube to allow an LED style Mag reflector to fit into the mouth… I like the head to be screwed almost all the way down

I inset the tail spring and bypassed it, while a full sized 26650 cell is fatter than a C and won’t fit I may bore it some day for the higher capacity full sized cell, so it’s already set up to accept it if/when I do that…

A wall shot on low in my Limo Room, we have 5% tint on the windows as my wife used to have bad migraines. I used a Samsung LH351D 5000K 80 CRI on a hand carved 13mm BLF/ Alex Wells DTP copper MCPCB, reflow soldered together. Built a PZL driver with 12 of the 350mA 7135 chips, tail amperage shows 3.35A on a Red Efest 26500 at about 97% charged. (This is a 4 year old cell)

This light really fits my hand nicely, with Bistro as the UI it’s pretty versatile and an automatic win for me, also have an AR coated lens in place. This is just one of those satisfying builds that gives one the feeling if a guy could only have one light, this one would definitely be a contender…. Wink

WICKED hot today, my thermometer was showing 100º by 9:11AM. Same thermometer shows 116.8º on the porch, a different thermometer with a probe right outside my window shows 108º. We tied a record yesterday with an official 106. Blistering out there, and sultry boiling hot at the lathe. But I love it that way, lol.

How remiss of me! It pulls 3.35A at the tail with the old 26500 not quite holding a full charge. (shouldn’t matter with the regulation chips)

1. 0.6355 lumens
2. 9.35
3. 54.855
4. 170.43
5. 250.47
6. 472.305
7. 986.7

With an 18ga spring bypass in the heavy steel tail spring it makes 1045.35 lumens

For the noobs out there… I’ve built hundreds of lights, and yet when I built the PZL driver last night it was direct shorted. I gradually removed components until the board was bare and still, it was a direct short! So I started over and built a new one with the same components, this time fully successful. Sometimes things just go wrong, it is what it is. Don’t be discouraged, take the time and check it out, start over if/when you have to. All part of the game. Big Smile

PZL is a puzzle of a driver, the component’s placement are listed on the mask under the MCU, you have to leave the MCU til last to see where everything goes! lol It has dual channel capability like our FET+1 drivers, but instead of using an FET it’s got multiple 7135 chips. I stacked 4 extra for the little more power. This driver was done by Alex (Wight here ) in a jovial moment. Wink

The other side is 6 of the 7135 regulation chips, the one to the right of “BLF” is the moon channel. Wink (With BLF TDC)

Old Lumens showed me how to stack chips. Wink

And I have all his kit, so a lot of my Maglight mods are based on stuff from Justin.

There’s been a LOT of people help me out along the way here, don’t ya know?! I think I about drove Comfychair crazy back when we were starting the FET craze. lol

All the buzz these days about price point. Man, I bought that chopped Red 1D Maglight from JayRob making 1000 lumens from a de-domed XM-L! Price point? How about $165! And I LOVED IT! (Ok, I didn’t exactly love spending that much on a flashlight but I loved the light, for sure! It used a 32650 protected cell from NOVAE. Anyone heard of em? All that was available in that size back then…

Edit: Come to think on it, the XM-L was domed, we started de-doming long after that.

Nice work on the Maglite Dale, and those are some good old BLF members you mention! I have been here for 6 years only but the turnover of members has been so fast that it feels much longer.

To your 12,200, right? Between the three of us we have posted 42,200 times! OMG! Shocked

(believe me, I know, y’all are contributing worthwhile studies and builds and I’m constantly hammering drivel into the forum…) Silly

If I sat here for a week and went back through my post’s and randomly deleted stuff, would it change my post count. lol Who was it did stuff like that a while back? Why does a squirrel come to mind? Who was it that managed to keep his post count the same no matter what he said? Where’sFoy?

20 minutes to 6 in the evening, it’ll likely still be in the 90’s at midnight…

We don’t advise going barefoot… 136.8ºF on the asphalt! And this not even the hot point of the day!

Nice lasers CRX!!!

Are you sure those are just 1.5 MW? I thought with 1.5 MW lasers you couldn’t see the beam unless you put smoke or steam in front. The beams from your lasers are very visible in your pictures. That looks a heck of a light brighter than those little 5 MW cat-toy lasers you buy at the grocery store.

Smoke Wink

So I calculated them at 400mA current draw * 4.1v cell voltage /1000 = 1.64mW
Does that sound about right?

@Firelight2, I don’t really think CRX has a 1.5MW laser. Not even a Samsung 30T could output that much power, even 1000 of them would just cut it close.

Also, I think he would’ve left a whole in all of the houses in his neighboor hood, and the FBI and CIA would probably be at his heels.

@DBCustom, back on track, how can you actually survive in this kind of weather? Your energy bill must be ludicrously high, through the stratosphere.

Now, you should probably paint all of your house white, put solar panels everywhere you can, wear white clothes all the time during the summer, have a house isolated with aerogel, and everything possible to make it bearable.

Is that how you calculate the laser CRX? I have a blue one that uses 2 18350’s, pulls … well… all of a sudden I can’t be sure what it pulls, I thought it was 3.3A at the tail… it’s supposed to be like 3W or something. I know it is quite strong, will burn a yellow jacket nest at 25-30’… it doesn’t catch on fire due to the larvae inside but it smokes and smolders. It’s kind of difficult to take the tail current reading because the beam will burn things, guess I can take it outside and lock it down in a bench vise pointed up into the sky, take the reading that way to be on the safe side (provided there’s no airplanes overhead)

My green laser, with a just measured .465A at the tail current draw…

This one is using my DBC-04 battery tube repurposed and with a marine bronze head. I now also have a SS aspheric focusing lens on it.

House is white, I wear cotton, I was born in August when it was 111º, much prefer heat to cold, have worked outdoors the majority of my life. When I delivered building materials, I drank some 3 gallons a day. A gallon of sweet tea to start with and filled up the jug twice with water after that. All in a day’s work.

A very quick reading on my blue laser shows 1.58A at the tail from 2 Aspire 18350’s. So that’s 1580mA, right? So would that be multiplied x 8.4V? For 13272 divided by 1000 for 13.272mW? Or 1.327 Watts? Am I figuring that wrong?

Shining the beam a mile across the lake…

Oh god. That is 13,2W correct?

An average laser will have an efficiency of 5-10%. It could be higher, but this is just theoretical.

That means your laser’s power is between 0,66W and 1,32W.

Both measurements are extremely dangerous to anybody which has a retina, and highly illegal in almost all countries in the world.

When I got it I was told it had been used pretty hard and probably wouldn’t make it’s “new” ratings of 3.3W. So this 30% level is probably close to correct. Wink It’s a 9mm Nichia diode that cost several hundred dollars when new.

Yeah, it’s kinda scary. A silent gun, as it were. I don’t keep cells in it and keep it locked up… much like a firearm.

The green one won’t burn things, still, I don’t “play” with it as it is really difficult to find a place to shine it since the green carries so stinking far. I’ve been able to see the green beam hit a telephone antenna/tower 2.2 miles from here.

Edit: Of course the lasers are dangerous, but when you grow up shooting guns you know the danger is relevant, retina perhaps but not so much skin from any real distance, quite unlike a firearm. Wink My gunsmith buddy told me a long time ago that a laser was a good training tool for proper firearm safety, being able to see the beam of light shows you just how difficult it is to point a gun in a safe direction. Really expands the mind’s scope on how to handle a loaded weapon. Obviously, neither are toys to played with or handled lightly.

Damn. Throws farther than the BLF GT in the palm size of your hand.

I would be more scared to hold this laser in my hands than an actual rifle though.

How much did that laser diode cost?

I studied up on lasers when I first got one, the mediocre strong green lasers can cause damage to the retina for miles, like 7 miles, and can be quite disturbing for 11 to 14 miles. At distances over a quarter of a mile or so, though, the auto-reaction to blink can be sufficient to prevent harm, irritation perhaps but not a burned hole in the retina. That’s on a 200mW green laser, which is what mine is supposed to be rated at. Well, my other one. This one is from a more reputable source that guarantee’s it to be 50mW at a minimum. I think I paid around $60 for the green diode.

I got the blue one on a sort of trade, as a used laser. Like I said, new the Nichia 9mm at 3.3W is over $300. It’s in a solid copper housing.

In the end, pretty worthless to have as you can’t do anything with them if you have a conscience. Wink
