Powerful LED cordless spotlight (battery from a power tool)




The master-master has to work a lot at night and for work you need high-quality lighting. The peculiarity of his work is that quite often there is no access to the electric network. Having decided to make a searchlight on his own, the master decided to stick to the following parameters:
-The projector should shine brighter than the battery models on the market
-Battery life should be at least two hours
- The battery must be a standard 18 V from a power tool (in this case, Makita)
-The spotlight must have additional sockets for additional power. equipment
-The cost should be within 60 pounds (about 5 thousand rubles)

Tools and materials:

- 50 W LED outdoor floodlight;
-Switch;
-Fuse;
- Aluminum box 188 x 120 x 57 with class IP54;
-Electric socket;

- Oil seals 20 mm;
-Profile;
-Drill;
-Ushm;
-Fasteners;

-3D printer;
-Soldering accessories;
-Screwdriver;
-Welding machine;



Step One: Adapter
To use a battery from a power tool, you need an adapter. The master printed the case on a 3D printer (available on), and purchased the connector itself.


Step Two: Inverter
To supply a 220 V searchlight, the master purchased a car inverter. I disassembled it, took out the board and cut the wire going to the car plug (not at the root).


Step Three: Buck Converter
The inverter works from the vehicle’s on-board network of 12 V. The Makita battery is 18 V at the output of the battery. Therefore, the master installs a step-down converter in the circuit with the following parameters: 24-12 V 5A 60 W.


Step Four: Build
Now proceeds to assembly. Marks and cuts out openings for switches, sockets, fuses in the housing. Fastens them.




Secures the spotlight to the box. Starts a wire from it inside the box.




Installs the inverter board inside the box, connects.




Step Five: Stand
The master made a stand out of a profile pipe. Cut to size. Cooked. I screwed the spotlight to the stand.









All is ready.

Examples of the searchlight.
Without lighting.

With the spotlight on.

The master is pleased with his work. The basic requirements set during the design are fulfilled. The searchlight shines brighter than similar industrial models, compatibility with standard batteries, battery life of at least 2.5 hours, additional connectors are installed. Only the master slightly exceeded the budget and the searchlight cost him £ 70 (about 6 thousand rubles). But this happened due to a burnt inverter, which was subsequently replaced by a more powerful 15 A.

According to the master, a less powerful searchlight of 20, 30 or even 10 watts would be enough for lighting.

I can dig, but I can not dig!

...- Can you make a ladder, for example?
...- I can! ... But I will not! Because it’s already very fucking to dig !!)))
(continuation of the joke)
work with hands out of reach of hands! )))). ... Wow ...))))
I can dig, but I can not dig! And by the way, all enti antigravitators, inertioids and other gravity caps are just outside the reach of the hands (and not with the hands. And, it seems, after consuming a certain amount ...)! smile
I can do specific work with my hands and within reach of my hands!

You think, surprised !!! )))) Now, if you could perform specific work with your hands outside the reach of your hands! )))). ... Wow ...))))
in
do specific work with your hands and within reach of your hands!

Inspired by:
"Vodka in small doses is useful in any quantity!" (Folk wisdom)))))
This is your hands so long
No, my hands seem to be normal, just me I can do specific work hands and within reach of hands! smile
I've always had enough good (I emphasize - good) headlamp, it’s enough to illuminate the workspace, and this is usually, within the reach of my hands! smile

I have a headlamp on an L2 diode and powered by two 18650. Good, as I think ... But now, I obviously do not have enough arm lengths))))
Because, if you defocus the lens on it, it will illuminate (very brightly) the yard by 10-20 meters ... You can also see further, but not "like in the afternoon" .. It’s like a car headlight ...)))) . And if you "put it in a bundle" (I don’t know why this function is needed from the forehead), then at night it’s "fumbling with the beam" a couple of hundred meters ...
Uh ... Is it your hands that are so long, or is it just that the quality requirements for the headlamps are underestimated?
So I'm not normal. And I don’t sleep during the day and at night.
Yes, and I often do not sleep at night, I think I'm an “owl”! smile

doesn't want a powerful LED rechargeable floodlight
I've always had a good (I emphasize - good) headlamp, it is enough to illuminate the workspace, and this, as a rule, is within the reach of my hands! smile
Pechkins sleep at night and do not interfere with their harmful advice
Our grandfathers said: "During the day, a nun, at night he makes funerals!" And more: "Aki thaw in the night!" Normal people (according to your Pechkina) sleep at night! Good deeds at night do not! smile
According to the master, a less powerful searchlight of 20, 30 or even 10 watts would be enough for lighting.

... And then, suddenly, the Master realized that he no longer wants a powerful LED battery searchlight, went to Ali and bought a flashlight on the T-6 for 4 pounds ...)))))

Well, why exactly does it work at night?
-so it works at night that all sorts of Pechkins sleep at night and do not interfere with their harmful advice
And at night he repairs the lighting
Well, why exactly does it work at night? But Pechkin is not harmful, he is useful, without him all sorts of Matroskins and Balls will do this !!! smile
Author
I understand who you remind me of. Postman Pechkin. The same harmful-)))
And at night he repairs the lighting, because he works as an electrician
The work is decent, like, but I had a question:
you have to work hard at night and to work you need high-quality lighting. The peculiarity of his work is that quite often there is no access to the electric network
What can be done at night without access to the mains? Judging by the photo, it breaks into the garage! smile
