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 ...

Mount it on the side of the printhead and see if it hits when the head goes all the way over. If so then you need to cut out what it hits

What about P600 as UV printer ? Is there more room for uv diodes ? What about uv cartridges ? Are they available ? Or using standard uv dampers and bottles is better way ?

I tested my little 60w module..today .... as suggested by few guys I moved it a bit up let say 4-5mm over printing head level to cover wider area and avoid polymerisation on the head itself ...I tested full platen printing and it works fine ....constant current led driver used ...seems like it is scratch proof ..too I was not able to scratch it easy even with sharp knife .... more testing soon :) module is water cooled :) I will use 5-10l of destiled water and fish tank pump...Today I used 45l but it is too risky to have such big capacity...heasink is almost freezing but uv under seem to be so strong I may even set dimmer to way lower power

you can buy a little radiator and fan from china and a pump with header tank for cooling complete system hold less than a litre of water and will work all day without getting hot

I was somewhat serious. Some lights are thin enough to fit. 

Andy will little uv as my one installed on L1800 works fine with  P600 . I have spare brand new p600 which can be converted.L1800 have cheep printing heads but it is quite slow ...i just wonder if P600 will do the job better ?

i think you would need to replace eco solvent print head for uv along with all ink lines, dumpers and catridges and maybe cap.

dx5 uv head is like this for example:

https://www.alibaba.com/product-detail/original-mimaki-jv33-printer-jv5-printhead_60726433769.html?spm=a2700.7724857.normalList.12.3f001800l124Fo&s=p

P600 is coming with gold ecosolvent head and caping station ......I have L1800 converted and it works so good ...I just wonder if P600 will be faster ....as it have 4 chanells for white... or 3 for white and one for varnish ....which will helps mi prints on glass...acrylic ans some metals..... as with L1800 i need to use manual primer aplications....

it melts eco solvent heads after a while as far as i know. as for l1800, if it’s head same with r1400; i have got one looks same 6 channel. it dx5 and dx7 atleast 3 times faster at 1440x1440. also you can go down to 720x720 on dx5 and dx7 heads which will insanely increase your print speed on top of that. Also can fire 3-4 times more white ink and about 2x cmyk on a pass.

edit: also r1400 clogs faster.

Hmm my friend use led uv ink in 1500w for more than 2 years already .... never had any clogs ....and :) was not aware of cleaning caping station too:) so seems like it is not as bad.... of course on my L1800 I hade to replace dampera anb tubes plus caping station tubes to solven friendly and uv blocking ones..... otherwise it seems to works fine .... i have tested some uv ink under day light and it not cure... cure well when strong uv lamps is used close to it ....
