How to convert an old moving head filament light to a cob led light

I've converted an old 150w moving head light modifying the old one with a COB led.

A few things i wanted to point out.
1: the LED is not collimated. When retrofitting fixtures to LEDs, you need to add a small glass collimating lens to the chip to help it focus its light forward, that way less of it is wasted.
2: since LEDs run way cooler than bulbs, you didn’t *really* need the thermal sleeving for the wires, especially since they were going into an abrasion-resistant sleeve anyway. Doesn’t hurt anything, but doesn’t help it either.
3: that transformer you took out looks way heavier than the one you put in. I don’t know what your application is, but if these are flying, you should consider adding counterweights around the new transformer to balance out the fixture. When trussing, it is good practice to centerload the truss. If your lights aren’t balanced properly, the truss could tilt or sway, which can be extremely dangerous.
4: be careful what you cut on that LED! Many COBs use that strip on the side (that you cut to put spades on) to bridge the different sections of the LED together (in this case, 3). By cutting one tab, you would be disabling 1/3rd of the chip!
5: would have been cool to see it in action after the retrofit!
Despite the potential issues, i want to compliment your use of tools! It looks like you’ve been doing stuff like this for a very long time, and I’m always glad to see people who are comfortable enough to modify equipment and give it a new lease on life! Many salutes to you!
thank you for all the tips you gave me.
at that time i've made the video there wasn't so many video tutorial explaining what to do and what not to do.
I've only few notions of electrical arguments, i'm not a PRO.
Regarding the moving head, was a shitty and cheap moving head that i've found stored in the warehouse of the venue where i've been worked for a long time.
I know at this point youtube is full of "master of tutorial" and a tone of video regarding that.
I only made a SIMPLE video made by a SIMPLE guy for the owners of old stuff like that moving head before they throw it in the rubbish LOL.
Cheers
OMG! I WATCH THIS WHOLE VIDEO AND THERE'S NO ENDING?!?! Tell us about it. How did it work? was it focused? was it bright?
@ronnie doorzon me too
I am modifying old HES trackspots.. alot of these mods ignore the dimming and run directly off transformer (better put a fuse there!) After spending a year working out the electronics.. I learn that these cobs are not so good for high intensity spots.. I will try to find 20 degree lens like one suggested here.. just the thrasher music was worse than the final light output but these vids are awesome
Problem on this conversion is, by replacing the bulb with COB led, the center of the bulb where it produced light are tiny enough to be focused thru a tiny hole and amplified by a lens.. The Cob Led however is different, the source of light is coming from combined small diode and produced a powerful light but wider space than a single source of light. When it need to focus in the tiny hole, only few diode can get thru that is why it get's weak to be amplified by the lens. Result? weak lighting output. Best way to get a good result from this conversion is find a tiny LED that produced true pure 100watts or if there's a single diode that can do the job.
Ficou perfeito parabéns 👏🏽👏🏽👏🏽👏🏽👏🏽🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷🇧🇷
Very. Good man beem. Light experiment good working , thanks you ,,,,
Love🇧🇷
Nice video!. I just beat up my wife due to the music
good video it really helped me but the music ........
hello can you tell me where you bought the whole complete set of the conversion in usa
aliexpress
Have you had any issues after mod? Thinking of trying this.
worked for years
SHOULD HAVE SHOWN MORE THE EFFECT OF THE MOVING CONVERTED! ..................... SHOWING HOW THE LED BRIGHTNESS HAS BEEN, BECAUSE AT THE END OF THE VIDEO THE MEDIUM WAS LOW FINAL RESULT OF THE EFFECT PROJECTED ON THE WALL!
I do this for a living convert disco lights scanners moving heads you name it
you should make videos.. ill watch!!
hello simon,. do you do led replacement for movingheads?
Do you have any videos?
Hey
Can I get an email?
I have 16 moving heads (paky copies) that are 250 watt.. I’d like to convert to led.. any help would be GREATLY appreciated bro
Any video how to replace light buld at scaners type of Eurolite TS-150 and TS-255? I need this tutorial Thank you
We will
Did you find one? I'm thinking of retrofitting my Robe 250 DJ scans.
@@someoneelseable yeah i need to know how replace old lighting bulb for 100w led 😉
les recomiendo que no hagan esa conversion a led COB, lo que si les recomiendo es que lo hagan con LEDS de tipo CBT o SST de 90w en adelante. o en todo caso lo hagan el cambio con lamparas de mercurio de BEAM230 o 200 en adelante veran que los resultados son insuperables.
Una consulta en estás modificaciones lo que se remueve es principalmente lo que la parte de la bugia o se tiene que realizar cambios en el resto de transformadores ?
Tengo interés en realizar una modificación a una Robe 250AT Spot
@@roderingangelfloresrodrigu6190 si es 250MSD solo el colocar una lampara 7r, obiamente haciendo las adaptaciones del lugar donde va a ir ubicada la lampara nueva. no necesitas nada mas, un ventilador adicional para la punta de la lampara nada mas seria.
amazing i love it keep it up i support
thank you mate :)
Thank god for the mute button..... W T F is this noise dude ?!
Martijn Vv noise...only noise
lamp led 50watts ? o 100watts ?
Anyelo Navarrete 100w cob led
has comparado el led con la cabeza mobil con el bonbillo original ?
I’m sure this would not that good at all.
You need to focus the LED to a spot or it’s a wide loss of light.

Bro you are a pro
ironman thanx mate
😆 🤣
Plz help shape repair video send
Wery small heatsing.
the moving head have two fans..
I do enjoy the background music
250v wtf?
Just buy led lights. And get real music
Another one of these mods....
Where should I start?
Maybe with the "music"? That was just some random noise.
The wiring? Is that meant searious?
And you don´t seem like you have thougt of the diferent colorspectrum...
Incadesent, halogen, tungsten and leds all have diferent outputs of ligth.
If the head would be using normal gels, it wouldnt be that much of an problem.
but because of the heat an incadesent lamp produces they install dichroitic gels.
these are made for specific amounts of wavelength and you will never get the same colors.
some will just be shifted some tones, but other wont be brigth at all.
also, these reflectors and optics are the most important an precise part of such fixtures.
you probably didnt calculate the distances to the lenses....
also, as mentioned in oher coments, the beam angle of these leds is designed to be used as a wide flood, not a narrow spot.
most of the ligth outputed will go into nowhere.
Let's be honest. This fixture probably wasn't that amazing when it was in it's original configuration. It was never going on any tours. But for a small diy venue or festival it could be alright. People throw these kinds of lights out all the time, and they're often not worth the price of the lamp. Perfect for a slap together project.
All that being said, dude definitely needs a reflector and probably a lens
i don't really think he cares what you think.. if he did, he would of put more description of what he was using and the products.. this is HIS mod.. not anyone else.. i thought it was cool video..
This Music is 🤮
Где результат?
