    We has LED install inside the HP-L25500 awhile, but don't have time to connect. We just connect same power supply and individual switch for L25500 and the L28500 install LED later.

    Because to help to visual inside when print if media curve start hitting the print head, bad print, night time don't have light above areas.

    Here are some picture, not very much show detail inside when took photos.

    That is a nice idea.

    The L26500 has even less light. I'm going to copy you!

    Two of ours are done up the same way. New models should have them included IMO.

    How did you mount them? Any more details on how you hooked them up to the power supply?

    I am not electrician. I used the power plug with 12volt if you don't use any more, wiring same plug with L2550 & L2850, and our machine next together. On each machine add the small switch so you can turn off if don't need.

    Regarding the LED install, we bought the lowest LED with adhesive from Montroy. We had about over 6month on the machine no problem with heat.

    Anyone went to the show see the 3D lamination on Nissan Murano hood. We are bought 1 roll test on our window perf and will install next couple day.

    Does this interfere with the OMAS sensor?

    I thought about doing this. But I have a question.... Should cool white or warm white LEDs be used? Would one or the other would show you a better (correct) color on your prints.

    I should elaborate. I did slightly differently than kev. I used the strip LEDs and mounted them on the outside of the window facing in. Separate power supply. Connected to a timer that turns them on from 7am to 11 pm. Our print room for the latex machines just got new lighting but these LEDs really help. Using the bright white 6000k which isn't exactly color accurate but it's more about seeing pass quality without grabbing the flashlight. No issues with any sensors.

    Check it out Colorado....$25 for 16' of LEDs on amazon use an old power supply like an old phone charger or what not.

    How did you run the power wire? Through the machine or outside of the machine?

    Thought I would post my pics in here, keep stuff in the same thread for everyone.

    Got the bug to do this seeing this thread, we had some spare LED modules from past sign installs just sitting going to waste so I put them to good use. The power wire will get routed somewhere else once I figure out where I want to run it and keep it out of the way of the carriage.

    Don't know why lights are not factory in printers these days, it seems like some of the Chinese specials come with them.
