6 ink heads are probably more cost effective you can get a replacement head for about 1/10th of the price of the 8 ink heads and you  do have to replace a few heads,  UV light and temp have a lot to d

Yes they should be ok, you will need a heatsink to mount the leds to and a suitable power supply for them.

Hmm I set one of these 12v 1A and it was more than enough to cure ink I used so  go down as low you can ...Save your printhead life ...

I have made air cooling uv led lamp and tested more than 500 hours. it is 3.6w/pc*21/pc=75.6W one.

Operating voltage is max.25.4V, but I fix my dc power supply(smps) to 23.5V for continuous LED lighting and no clogging.

Printer is Epson p600, 8channel one. I can enjoy 1440*1440 resolution printing  long time, maybe more than one year without any clogging of printhead.

In my experience, bad Uv ink damages printhead seriously even though you lowered led power supply to enough safe zone.

Bad ink break the inner mechanism of printhead within several hour continuous printing.

Pls try to find quality uv inks to keep printhead in high condition.

Hello!
I am trying to assemble a UV printer.
You said you don't have to cut the printer if you use this slim LED.
Just buy this LED and a cooler and it's all right?
Did you use any other equipment?
These are the ones I am considering buying:

COOLER: https://pt.aliexpress.com/item/4000108937485.html

LED: https://pt.aliexpress.com/item/4000224260797.html

Please tell me if they would work for the printer.

Thanks!

Hello,
I went back to my project. This is my adaptation for the UV LED. I used the Epson housing.
Then I went to test the LED. It heats up a lot. When I turn on the voltage is at 27V and within a few minutes it drops and stabilizes at 24.7V.
I'm afraid about that.
Do you think this structure will be able to support?
I accept suggestions!
Thanks.

Hello Pompoko! I am using a power supply that I bought with the LED. According to the manufacturer, the LED needs 26-30V and 1200mA.
Did you ask me to be careful with the life of the LED or the print head?
Thanks.

The main thing is to limit the current to 1200ma or less. If you overdrive them it will damage them.

Also you should have a larger heatsink than what you are using, heat is the biggest killer of led's.

The current needs lowering as it's over driving the leds.

Are you using a fixed current power supply?

Going by the suppliers spec to get optimal performance stay within their limits but you can run a lower voltage.

That's the font I'm using. I bought from the same seller along with the LED.

Output Power - 200W

Output Voltage - 25-36V

Output Current - 1,3A

When I turn on the LED, I measure
24.7V and 1320mA

Olá!
Estou tentando montar uma impressora UV.
Você disse que não precisa cortar a impressora se usar este fino LED.
Basta comprar este LED e um cooler e está tudo bem?
Você usou algum outro equipamento?
Estes são os que estou pensando em comprar:

REFRIGERADOR:  https://pt.aliexpress.com/item/4000108937485.html

LED: https://pt.aliexpress.com/item/4000224260797.html

Por favor, diga-me se eles funcionariam para a impressora.

Obrigado!

esse modulo de led não presta. e projeto meu...   baixa qualidade.
