Replacing MR16 bulbs in disco light

[ShaunJUK]

Good Afternoon.

I am refurbishing 2 Chauvet Colour Bank 8 disco lights. These get very hot when in use as they use 8x 240v 50w JCDR Bulbs.

Is there any reason I can't replace them with an LED equivalent? I can't see an LED alternative as most MR16 are 12v. Would I be better changing them to GU10. Could they handle the flashing?

Thanks

That is a 12v bulb you have

Try an led equivalent

 

[ShaunJUK]

Thanks for your reply. I did however state it is a 240v bulb.

At least you have looked at the picture, clearly marked 240 volt. I would change socket to GU10 as they are really avaible as 230 volt.

Thanks. I have since seen a video on YouTube where the publisher says he has done this. Do you think LEDs will run in it ok?

I would get an LED (GU10 or whatever) and try it, even if you have to wire it to the back of the existing holder temporarily. The only reason it wouldn’t work is if they are switched with triacs - these are pulsed on and rely on a minimum current to hold them on for the rest of the half-cycle. LED current will likely be too low

I have used smart lights with the sound option, however it uses the microphone of your phone, so how long the phone battery would last I don't know.

I only did it to see how it worked, and it did work with some TCP strip lights, there are so many smart bulb manufacturers, and every bulb I have seems to need a different app, it did look good as it changed colour with my speech, but I have only used it as an experiment.

can’t guarantee that they will work but worth a go?

any good?

There are multi ways of limiting the current in the LED elements of a bulb, resistor, capacitor or pulse width modulated controllers, the capacitor or resistor type is likely around 70 lumen per watt, and the PWM more like 110 lumen per watt, so if you get the poor quality lamps as @Sureitsoff? has linked to it will likely work OK, but likely you will have problems with more expensive types.

A problem you may encounter is the focus of the beams.

The halogen lamp will usually be a very small point source whereas a LED equivalent may be much larger so the lenses won't focus as well for creating beams.

I look at this and wonder how your going to get the colours with LED lamps, yes my LED lamp has the centre lamp colour changing so can get varying colours, but to get it to change colours disco style needs it to connect to the phones microphone. Can set it to just change at varying speeds, or to have one set colour, but a colour changing LED is typically around £10 so looking at around £80 to convert to LED.

I see it includes "Includes 8 color gels, (2) x red, (2) x yellow, (2) x blue and (2) x green" so maybe white bulbs will work, but also note "
Power: Switchable 110V/230V • Bulb: 8 x JCDR 50W 120V so question is how is yours configured? Reading the bulb it does say 230 volt 50 watt, but it seems likely you will need a full rebuild to change to LED the panel seems to offer many options, and says

so I would not expect it to work with other than 50 watt lamps.

Good, at least from that picture you don't have to worry about beams, it's just a flood. Would be interested to know how the colors look in the gel as leds don't output a smooth spectrum of light.

Also, how does it switch the lamps to make it chase?

If dimmed i.e Ramps up and down in a fade, the leds may not like having dimmers attached to them.

If it does sound to light it probably has a built in mic to pick up ambient sound.

I use a fair number of LED Lamps and buy them in different beam widths.
120°, 38° etc
I run them in birdie mini PAR cans
